Answers
Answer:
(c)(i) The order of the reaction based on the graph provided is first order.
(ii) 99% of the cyclobutane would have decomposed in 53.15 milliseconds.
d) Rate = K [Cl₂]
K = rate constant
The justification is presented in the Explanation provided below.
e) A catalyst is a substance that alters the rate of a reaction without participating or being used up in the reaction.
Cl₂ is one of the reactants in the reaction, hence, it participates actively and is used up in the process of the reaction, hence, it cannot be termed as a catalyst for the reaction.
So, this shows why the student's claim is false.
Explanation:
To investigate the order of a reaction, a method of trial and error is usually employed as the general equations for the amount of reactant left for various orders are known.
So, the behaviour of the plot of maybe the concentration of reactant with time, or the plot of the natural logarithm of the concentration of reactant with time.
The graph given is evidently an exponential function. It is a graph of the concentration of cyclobutane declining exponentially with time. This aligns with the gemeral expression of the concentration of reactants for a first order reaction.
C(t) = C₀ e⁻ᵏᵗ
where C(t) = concentration of the reactant at any time
C₀ = Initial concentration of cyclobutane = 1.60 mol/L
k = rate constant
The rate constant for a first order reaction is given
k = (In 2)/T
where T = half life of the reaction. It is the time taken for the concentration of the reactant to fall to half of its initial concentration.
From the graph, when the concentration of reactant reaches half of its initial concentration, that is, when C(t) = 0.80 mol/L, time = 8.0 milliseconds = 0.008 s
k = (In 2)/0.008 = (0.693/0.008) = 86.64 /s
(ii) Calculate the time, in milliseconds, that it would take for 99 percent of the original cyclobutane at 1270 K to decompose
C(t) = C₀ e⁻ᵏᵗ
when 99% of the cyclobutane has decomposed, there's only 1% left
C(t) = 0.01C₀
k = 86.64 /s
t = ?
0.01C₀ = C₀ e⁻ᵏᵗ
e⁻ᵏᵗ = 0.01
In e⁻ᵏᵗ = In 0.01 = -4.605
-kt = -4.605
t = (4.605/k) = (4.605/86.64) = 0.05315 s = 53.15 milliseconds.
d) The reaction mechanism for the reaction of cyclopentane and chlorine gas is given as
Cl₂ → 2Cl (slow)
Cl + C₅H₁₀ → HCl + C₅H₉ (fast)
C₅H₉ + Cl → C₅H₉Cl (fast)
The rate law for a reaction is obtained from the slow step amongst the the elementary reactions or reaction mechanism for the reaction. After writing the rate law from the slow step, any intermediates that appear in the rate law is then substituted for, using the other reaction steps.
For This reaction, the slow step is the first elementary reaction where Chlorine gas dissociates into 2 Chlorine atoms. Hence, the rate law is
Rate = K [Cl₂]
K = rate constant
Since, no intermediates appear in this rate law, no further simplification is necessary.
The obtained rate law indicates that the reaction is first order with respect to the concentration of the Chlorine gas and zero order with respect to cyclopentane.
e) A catalyst is a substance that alters the rate of a reaction without participating or being used up in the reaction.
Cl₂ is one of the reactants in the reaction, hence, it participates actively and is used up in the process of the reaction, hence, it cannot be termed as a catalyst for the reaction.
So, this shows why the student's claim is false.
Hope this Helps!!!
(i) The order of reaction is first order.
(ii) It requires 53.15 miliseconds for 99% decomposition.
(d) Rate law = k [[tex]\rm Cl_2[/tex]].
(e) Chlorine gas is the reactant. Thus student claim is false.
(i) The order of reaction can be determined with the help of a graph. The graph depicts the exponential behavior of decomposition of cyclobutane with respect to time.
The graph depicts the reaction to be of first-order kinetics. The general concentration expression can be:
[tex]\rm C_(_t_)\;=\;C_(_0_)\;e^-^k^t[/tex]
Where, [tex]\rm C_(_t_)[/tex] = concentration at time t
[tex]\rm C_(_0_)[/tex] = initial concentration 1.60 mol/liter
k = rate constant
for first order reaction,
k = In [tex]\rm \frac{2}{Half\;time}[/tex]
From the graph, half time = 0.008 sec
k = In [tex]\rm \frac{2}{0.008}[/tex]
k = 86.64 / sec.
(ii) The time required for 99% decomposition can be calculated, by calculating the [tex]\rm C_(_t_)[/tex] for left 1 % solution.
[tex]\rm C_(_t_)\;=0.01\;C_(_0_)[/tex]
0.01 [tex]\rm C_(_0_)[/tex] = [tex]\rm C_(_0_)[/tex] [tex]\rm e^-^k^t[/tex]
-kt = -4.605
t = 53.15 miliseconds
(d) The rate law is obtained against the reaction.
In rate law, the intermediates that appear in the reaction are removed, and the equation has been formed.
The slow step is the formation of Chlorine. Thus the rate law will be:
Rate = k [[tex]\rm Cl_2[/tex]]
(e) The catalyst function in improvising the rate of the reaction. Since, the reaction has chlorine as the part of the reactant, it is consumed in the reaction and thus does not act as a catalyst. Thus the claim of the student is false.

Answer:
A
Explanation:
First, we're given that the atmospheric pressure is 744.8 mmHg. However, this includes the pressure of the Zinc and the pressure of the water; we only want the pressure of the water, so subtract its pressures (23.8 mmHg) from 744.8 mmHg: 744.8 - 23.8 = 721 mmHg.
Now, we can use the ideal gas law: PV = nRT.
- the pressure P is 721 mmHg
- the volume V is 7.80 L
- the moles n of Zinc is what we want to find in order to calculate the mass
- the gas constant R is 62.36 L mmHg / (mol K)
- the temperature T is 25.0°C, or 25.0 + 273 = 298 K
Plug all these in:
PV = nRT
(721 mmHg) * (7.80 L) = n * (62.36) * (298 K)
n ≈ 0.303 mol Zn
We need to convert this to grams, so use the molar mass of Zinc, which is 65.38 g/mol:
[tex]0.303molZn*\frac{65.38g}{1mol} =19.8gZn[/tex]
Thus, the answer is A.

In your body, carbon dioxide, CO2, dissolves in the blood to form carbonic acid, H2CO3 as follows:
CO2(g) + H2O(l) ⇆ H2CO3(aq)
After heavy exercise, your body builds up carbonic acid, which can become toxic in high enough concentrations. This can lead to panting like a runner after a race which helps you to more quickly breathe out carbon dioxide and reduce its concentration.
1) What is the effect on the reaction balance of panting?
2)What will be the effect on the concentration of carbonic acid – explain your reasoning
3)If you hike to the top, would the low pressure at high altitude help reduce or increase the carbonic acid concentration? – Explain your answer.
4)Some carbon dioxide dissolves in your blood directly as CO2(aq). What is the effect of the lower pressure at a mountain top on the ability to directly dissolve CO2(g)?
Answers
Panting after exercise reduces carbon dioxide levels in the blood, decreasing carbonic acid and helping restore pH balance. At higher altitudes, lower pressure reduces blood's capacity to hold CO₂, potentially leading to decreased carbonic acid concentration but also complicating the body's regulatory mechanisms. Direct dissolution of CO₂ in the blood is also affected by lower pressure.
Effects of Panting and Altitude on Carbonic Acid Concentration:
Panting after heavy exercise increases the expulsion of carbon dioxide, which in turn decreases the concentration of carbonic acid in the blood. This process reestablishes the pH balance, reducing the risk of acidosis caused by the buildup of lactic acid and carbonic acid during strenuous activity. Furthermore, hiking to a higher altitude, where the pressure is lower, would reduce the ability of blood to hold carbon dioxide. This reduction leads to faster removal of carbon dioxide from the blood, which would tend to decrease carbonic acid concentration. However, due to reduced oxygen availability and potential respiratory adjustments such as hyperventilation, the effect on blood pH can be complex at high altitudes.
Lower pressure at high altitudes also affects the direct dissolution of carbon dioxide (CO₂) in blood. At lower pressures, less CO₂ can be dissolved directly, which might necessitate increased respiratory rates to compensate for the reduced ability to carry carbon dioxide away from tissues. Overall, both mechanisms work to ensure the body can maintain a stable internal environment, particularly during varying physical demands and environmental conditions.
A student prepares 150.0 mL of 1.40 M HCl using 35.0 mL of a stock solution. What is the concentration of the stock solution? Use M subscript i V subscript i equals M subscript f V subscript f..
Answers
Answer:6.0M
Explanation:see attached photo
The concentration of the stock HCl solution used to prepare 150.0 mL of 1.40 M HCl from 35.0 mL of the stock solution is 6.00 M.
To find the concentration of the stock solution of HCl used to prepare a diluted solution, we can use the dilution equation MiVi = MfVf, where Mi and Vi are the concentration and volume of the initial stock solution, and Mf and Vf are the concentration and volume of the final diluted solution.
In this case, the student has prepared 150.0 mL of 1.40 M HCl by diluting 35.0 mL of a stock solution. To find the concentration of the stock solution (Mi), we rearrange the equation to solve for Mi:
Mi = (MfVf) / Vi
Substituting the given values:
Mi = (1.40 M × 150.0 mL) / 35.0 mL
Mi = (210.0 × mL) / 35.0 mL
Mi = 6.00 M
Therefore, the concentration of the stock HCl solution is 6.00 M.

hope this helps
Explanation:
Final answer:
To slow climate change, it is crucial to reduce energy use, switch to alternative energy sources like solar and wind, and enhance carbon sinks by planting forests.
Explanation:
To slow down climate change, we should focus on several key actions. First, we need to reduce energy use, which could include measures like turning off lights when not in use and driving more fuel-efficient cars. These steps help because much of the electricity and transportation relies on burning fossil fuels, which releases large amounts of carbon dioxide.
Another important action is to switch to cleaner alternative energy sources, such as solar, wind, and geothermal energy. These sources produce little to no carbon emissions compared to fossil fuels like coal, oil, and natural gas. Additionally, increasing the use of technologies like hybrid cars can drastically reduce air pollution and fossil fuel consumption. Moreover, we can combat climate change by enhancing carbon sinks, such as planting more forests which absorb carbon dioxide from the atmosphere.

Answers
Answer:
The new pressure will be 74.8 kPa
Explanation:
Step 1: Data given
Volume of the N2 gas = 500 mL = 0.500 L
Temperature = 10.0 °C = 283 K
Pressure = 108 kPa
The volume is increased to 750 mL = 0.750 L
The temperature is increased to 21.0 °C = 294 K
Step 2: Calculate the new pressure
P1*V1 / T1 = P2*V2 / T2
⇒with P1 = the initial pressure = 108 kPa
⇒with V1 = the initial volume = 0.500 L
⇒with T1 = the initial temperature = 283 K
⇒with P2 = the new pressure = TO BE DETERMINED
⇒with V2 = the increased volume = 0.750 L
⇒ with T2 = the increased temperature = 294 K
108 * 0.500 / 283 = P2 * 0.750 / 294
P2 = (108*0.500 * 294) / (283*0.750)
P2 = 74.8 kPa
The new pressure will be 74.8 kPa

weeds?
Answers
Answer:
Groundwater pollution
Explanation:
Pesticides, when sprayed on crop plants, are able to flow below the surface of the ground, reaching water-bearing aquifers, thereby contaminating groundwater, making it unsuitable for both human and agricultural uses.
Final answer:
The type of water pollution produced from chemicals used to kill bugs and weeds is due to pesticides, including insecticides and herbicides, which contaminate water bodies through runoff and leaching into groundwater.
Explanation:
The type of water pollution produced from chemicals used to kill bugs and weeds is primarily due to pesticides, which include insecticides, herbicides, and fungicides. These chemicals often run off during rainfall into nearby rivers, lakes, and infiltrate into groundwater, creating a significant environmental concern. Contaminated water can cause an overgrowth of water plants and algae, which in turn, results in dead zones. Moreover, if humans consume water contaminated with these substances, they can fall ill from a variety of health issues, including cancer, damage to the central nervous system, and developmental defects. Therefore, the chemicals from pesticides and herbicides used in agricultural and garden applications significantly contribute to water pollution.

C) It is a coefficient representing that there are 13 oxygen molecules in the reactants
D) It is a subscript representing that there are 13 oxygen atoms in the reactants
Answers
Final answer:
A number placed in front of a compound or an element in a chemical equation, such as 13 in front of oxygen, is a coefficient that indicates the number of molecules present, meaning there are 13 oxygen molecules in the reactants.
Explanation:
When you see a number placed in front of a compound or an element in a chemical equation, such as the number 13 placed in front of oxygen, this number is referred to as a coefficient. Coefficients are used in chemical equations to indicate the number of molecules or atoms involved in the reaction. Unlike subscripts, which denote the number of atoms of an element within a molecule, coefficients tell us how many units of a molecule or an elemental atom are present. Therefore, if we see a 13 in front of oxygen in a chemical equation, it indicates the presence of 13 oxygen molecules. This means that the correct answer is "C) It is a coefficient representing that there are 13 oxygen molecules in the reactants".
If there was a high pressure system in your area and a bunch of clouds were blown in from a different direction, how would the pressure system in your area change? Would it change or stay the same
Answers
The pressure system in the area would likely change due to the introduction of clouds from a different direction.
Clear skies in a high-pressure system occur because descending air inhibits cloud formation; cloud movement suggests a different air mass.
Arrival of a cloudy air mass can disrupt the existing high-pressure system by weakening it.
The high-pressure system might shift position, moving away or being displaced by the incoming low-pressure system.
Persistence of the high-pressure system depends on its strength and reinforcement by other atmospheric conditions; clouds may be temporary.
Interaction between high and low pressure can form a frontal boundary, triggering weather changes like precipitation.
Cloud introduction from another direction indicates a weather pattern change, affecting the area's pressure system.
Outcome varies based on the strengths and characteristics of both pressure systems and the associated air masses.

Which of the following is NOT involved in recording climate data?
A. Investigating air bubbles trapped in ice cores.
B. Analyzing species of pollen.
C. Identifying phosphorus levels in fossils.
D. Studying tree rings.
Answers
The method not involved in recording climate data is identifying phosphorus levels in fossils. Climate scientists commonly use ice cores, pollen analysis, and dendrochronology to understand past climate conditions.
So, the correct answer is C. Identifying phosphorus levels in fossils.
Explanation:The option that is NOT involved in recording climate data is indentifying phosphorus levels in fossils. Phosphorus levels in fossils are typically not used to record historical climate data. Instead, they may be more relevant in studies of biogeochemical cycles or ancient ecosystems.
Climate scientists use various methods to reconstruct past climates, known as proxy data. Some of the common proxies include:
Investigating air bubbles trapped in ice cores to analyze atmospheric composition and temperature from the past.Analyzing species of pollen to infer the types of vegetation and therefore the climate of the time.Studying tree rings, also known as dendrochronology, which can indicate the age of a tree and provide information about historical weather patterns and climate conditions.Each of these methods contributes to the understanding of Earth's climate history and changes over time.
So, the correct answer is C. Identifying phosphorus levels in fossils.
Final answer:
Identifying phosphorus levels in fossils is NOT involved in recording climate data. Tree rings, ice cores, and pollen analysis are used to study past climates. Phosphorus levels give geochemical information not directly related to climate.
Explanation:
Of the options provided, the one that is NOT involved in recording climate data is C. Identifying phosphorus levels in fossils. The other options, like investigating air bubbles trapped in ice cores, analyzing species of pollen, and studying tree rings, are all common proxy methods used by scientists to reconstruct past climates. Phosphorus levels in fossils generally provide information related to the geochemistry of the environments where the organisms lived, rather than direct climate data.
Both tree rings and ice cores are essential proxies in paleoclimatology. Tree rings provide annual records that can be used to infer temperature and precipitation patterns, while ice cores can reveal atmospheric composition and temperature data over longer time periods. Pollen analysis helps in reconstructing past vegetation and therefore, the climate that supported such vegetation.

You exert the same force on two objects of different masses. Which object will have the greater acceleration? Explain your answer.
Answers
When the same force is applied to two objects with different masses, the object with the smaller mass will experience a greater acceleration.
How to get the objectThis is in accordance with Newton's second law of motion, which states that acceleration is inversely proportional to mass when force is constant.
Less massive objects accelerate more easily in response to a given force, while more massive objects require a greater force to achieve the same acceleration.
Read more on acceleration here https://brainly.com/question/460763
#SPJ3
The object with the smaller mass will have the greater acceleration.
According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. This relationship is given by the equation:
[tex]\[ a = \frac{F}{m} \][/tex]
where [tex]a[/tex] is the acceleration, [tex]F[/tex] is the force applied, and [tex]m[/tex] is the mass of the object.
Given that the same force [tex]F[/tex] is applied to two different objects, the acceleration [tex]\( a \)[/tex] of each object will depend on its mass [tex]\( m \).[/tex] If we denote the force as \( F \), and the masses of the two objects as [tex]\( m_1 \) and \( m_2 \),[/tex] with [tex]\( m_1 < m_2 \)[/tex], the accelerations [tex]\( a_1 \) and \( a_2 \)[/tex] can be calculated as:
[tex]\[ a_1 = \frac{F}{m_1} \][/tex]
[tex]\[ a_2 = \frac{F}{m_2} \][/tex]
Since [tex]\( m_1 < m_2 \)[/tex], the fraction [tex]\( \frac{F}{m_1} \)[/tex] will be greater than [tex]\( \frac{F}{m_2} \),[/tex]which means that \[tex]( a_1 > a_2 \).[/tex]
Therefore, the object with the smaller mass [tex]\( m_1 \)[/tex] will have the greater acceleration [tex]\( a_1 \)[/tex] when the same force [tex]\( F \)[/tex] is applied to both objects.
This conclusion is consistent with the inverse relationship between mass and acceleration as described by Newton's second law.
