Ethanol, C2H5OH, will combust in air according to the equation below. C2H5OH(l) + 3 O2(g) → 2 CO2(g) + 3 H2O(g) ΔHo = –1270 kJ/molrxn (a) Is O2(g) oxidized in the reaction, or is it reduced? Justify your answer in terms of oxidation numbers.
Answer:
O2(g) was Reduced
Explanation:
It is necessary at this point to restate the working definitions of oxidation and reduction.
Oxidation refers to increase in oxidation number. A chemical specie is oxidized in a chemical reaction if there is a positive increase in its oxidation number from left to right in the reaction.
A chemical specie is said to be reduced when there is a decrease in its oxidation number from left to right in a reaction. Hence reduction refers to a decrease in oxidation number.
Now let us focus on O2(g). Its oxidation number on the left hand side is zero. On the right hand side, its oxidation number decreases to -2. This shows a decrease in oxidation number. From our premises above, we can safely conclude that O2(g) was reduced in the reaction.
The answer to whether the Oxygen (O₂) is oxidized or reduced is that;
The oxygen (O₂) is being reduced.
Oxidation and ReductionWe are given the equation;
C₂H₅OH (l) + 3O₂ (g) → 2CO₂ (g) + 3H₂O (g) ΔH° = –1270 kJ/mol_rxn
Now, Oxidation in this context will be an increase in oxidation number. This means that we consider a chemical element in a chemical reaction to be undergoing oxidation if there is a positive increase in its oxidation number from left to right in the reaction. Otherwise, it is said to undergo reduction.
Now, when we assign oxidation numbers to the elements in the chemical equation, the oxygens in O₂ (g) would be zero. Meanwhile the oxygens in both CO₂ (g) and H₂O (g) are -2.
In conclusion, since the oxygens in both CO₂ (g) and H₂O (g) are -2, it means oxidation number has reduced and as such there is a reduction in oxygen.

If 135.7 J of heat are added to 54.0 g of water initially at 25.0 °C . What is the final temperature of the water?
Answer:
The final temperature of the water is 25.6 °C.
Explanation:
We have,
Heat added to water is 135.7 J
Mass, m = 54 g
Initial temperature was 25 °C
It is required to find the final temperature of the water. The heat added when temperature is increased is given in terms of specific heat capacity as :
[tex]Q=mc(T_f-T_i)[/tex]
[tex]T_f[/tex] is final temperature
c is specific heat capacity, for water, [tex]c=4.184\ J/g^{\circ} C[/tex]
So,
[tex]T_f=\dfrac{Q}{mc}+T_i\\\\T_f=\dfrac{135.7}{54\times 4.184}+25\\\\T_f=25.6^{\circ} C[/tex]
So, the final temperature of the water is 25.6 °C.
To find the final temperature of water after heat is added, the heat equation Q = m x c x ΔT is used. By dividing the amount of heat (135.7 J) by the product of water's mass (54.0 g) and its specific heat capacity (4.184 J/g°C), we find that the temperature increases by 0.60 °C. Thus, from an initial temperature of 25.0 °C, the water's final temperature is 25.6 °C.
To calculate the final temperature of water after a certain amount of heat is added, we use the formula
Q = m × c × t. Here Q represents the heat added in joules, m is the mass of the water in grams, c is the specific heat capacity of the water (which is 4.184 J/g°C), and ΔT is the change in temperature in degrees Celsius. For a given amount of water at an initial temperature, the added heat will increase the water's temperature by a certain amount based on this formula.
In this case, 135.7 J of heat are added to 54.0 g of water initially at 25.0 °C. The specific heat capacity of water (c) is a well-known constant, 4.184 J/g°C. The change in temperature (ΔT) can be calculated as follows:
ΔT = Q / (m × c)
ΔT = 135.7 J / (54.0 g times4.184 J/g°C)
ΔT = 135.7 J / (225.936 J/°C)
ΔT = 0.60 °C
The final temperature of the water is the initial temperature plus the increase in temperature:
T(final) = T(initial) +ΔT
T(final) = 25.0 °C + 0.60 °C
T(final) = 25.6 °C

a gas has a volume of 45.0 mL and a pressure of 760.0 mm. If the pressure increased to 850.0 mm and the temperature remained the same, what would be its new volume?
Answer:
40 mL
Explanation:
V2=P1V1/P2
You can check this by knowing that P and V at constant T have an inverse relationship. Hence, this is correct.
The new volume will be "40 mL".
Boyle's LawA gas equation or principle essentially asserts that perhaps the pressure generated by something like a gaseous molecule (with a particular mass as well as constant temperatures) seems to be inversely proportional towards its volume.
According to the question,
Pressure, P₁ = 760.0 mm
P₂ = 850.0 mm
Volume, V₁ = 45.0 mL
V₂ = ?
By using Boyle's Law,
→ P₁V₁ = P₂V₂
or,
New volume will be:
V₂ = [tex]\frac{P_1 V_1}{P_2}[/tex]
By substituting the values,
= [tex]\frac{760\times 45}{850}[/tex]
= [tex]\frac{34200}{850}[/tex]
= 40 mL
Thus the response above is correct.

All isotopes of an element have the same number of neutrons. have the same number of protons. have the same atomic number. have the same mass number. have different chemical properties.
Answer:
ALL ISOTOPES OF AN ELEMENT HAVE THE SAME NUMBER OF;
1. PROTON
2. ATOMIC NUMBER
Explanation:
Isotopes are atoms with the same atomic number but different mass numbers. Isotopes of an element has the same number of proton which dictates the atomic number of the atoms. The difference in mass number is as a result of the difference in the number of neutrons. Isotopes of an atom have different physical properties but they exhibits the same chemical properties because neutrons have no influence on the chemical properties and the change or difference in neutrons will produce no effect on the chemical properties of the atoms. Neutrons only contributes to the mass of the atoms giving the isotopes of an atom different mass numbers. An example is chlorine with two isotopes, Cl -35 and Cl -37.
Properties Cl-35 Cl-37
mass number 35 37
atomic number 17 17
number of protons 17 17
number of electrons 17 17
number of neutrons 35-17 = 18 37-17 = 20
abundance in nature 75% 25%
From the given information;
all isotopes of an element do not have the same number of neutrons, have the same number of protonshave the same atomic numberdo not have the same mass numberhave the same chemical properties.An isotope is are two or more atomic element that contains the same equal number of protons in the nucleus of an atom but with a different number of neutrons.
They share the same similar chemical properties and they behave in the same manner in the chemical reaction but have different mass numbers due to the different number of neutrons.
The difference in their mass numbers influences the rate of their chemical reactions.
They also exhibit different stability. While some are stable, some are unstable, and they can be referred to as radioactive isotopes.
Therefore, we can conclude that:

In order to make a cold pack, do you want to use a chemical that absorbs energy or release energy?
Answer:
Absorb energy.
Explanation:
If you wanted to make a cold pack that absorbs heat (aka an endothermic reaction), then you'd want to use a chemical that absorbs energy. This would absorb the heat. Hope this helped :)
It is critical to evaluate the sort of chemical that will be utilised while creating a cold pack. The solution is dependent on the desired consequence of the cold pack.
What is the way for making the cold pack ?A cold pack is often made using an energy-absorbing substance. The most popular form of cold pack employs a chemical process to absorb energy from the environment, causing the pack's temperature to drop.
A "chemical cold pack" is another name for this sort of cold pack. A chemical cold pack's chemical reaction is often an exothermic reaction. This indicates that the reaction generates heat, which the pack absorbs and causes the temperature to fall.
Another application for a cold pack To absorb energy, a phase transition substance such as wax or glycol is used. A "phase change cold pack" is another name for this sort of cold pack. The phase change material absorbs energy from the environment, lowering the temperature of the pack.
This sort of cold pack is frequently used for medicinal purposes, such as relieving sprains and strains. Finally, when creating a cold pack, it is critical to consider the type of chemical that will be used. A chemical that absorbs energy is typically used to construct a cold pack, as this causes the pack's temperature to drop.

Using your understanding of environmental science, make a hypothesis about how these six vehicles compare with regard to total lifetime greenhouse gas emissions. Predict which ranking reflects least CO2 emitted to most CO2 emitted. (Note that all responses will be marked as "correct" at this point.)
Answer:
Answer is option (d) (lowest to highest)
We have to rank the six vehicles according to the CO2 emission causing an impact on global warming. We know that burning of coal has the highest emission of all fossil fuel so EV powered by electricity from it will be the highest impact on global warming with highest CO2 emission, next is burning of gasoline, but the CO2 emission can be varied by the process of the burning in engines obviously a high-efficiency burning will have less impact than a regular standard engine. So, after ICEV standard will have high CO2 emission than the ICEV (high efficiency), now the next will be EV which is having its electricity supplied by a mix of resources, the production involves both fossil and non-fossil fuel which make this vehicle more environmentally friendly than the full fossil fuel-based. The ICEV with less driving has the second least emission because you are not burning the fuel like other vehicles because of not driving the vehicle. In the last will be the EV having powered by electricity of wind it will be the least emission almost zero because it using wind power to generate electricity. Hence arrangement comes like this, EV(wind), ICEV(less driving), EV (mix of sources), ICEV (high-efficiency), standard ICEV, EV (coal) from lowest to highest CO2 emission.

nonmetals such as Cl combine with metals such as Na by what
Answer:
Ionic Bond
Explanation:
Ionic Bonds are formed through electrostatic attraction between two ions that are opposite charge (also meaning a metal and a nonmetal).
Final answer:
Nonmetals like Cl combine with metals like Na through ionic bonding, where Na donates an electron to Cl, resulting in the formation of a stable compound, NaCl, with drastically different properties from the individual elements.
Explanation:
Nonmetals such as chlorine (Cl) combine with metals such as sodium (Na) primarily through the formation of ionic bonds. In this type of chemical bonding, the metal atom, sodium in this case, donates its valence electron to the nonmetal atom, chlorine, creating oppositely charged ions. Sodium becomes a positively charged cation (Na+), and chlorine becomes a negatively charged anion (Cl-). These oppositely charged ions are then attracted to each other due to electrostatic forces, forming a stable crystalline compound, sodium chloride (NaCl), commonly known as table salt. The process of these elements combining leads to a compound that has entirely different properties from its constituent elements. For example, while individual sodium atoms react explosively with water, and chlorine gas is extremely toxic, combined as sodium chloride, they form an essential compound for life that is stable and nonreactive in nature.

What type of bond would occur between lithium (Li) and oxygen (O)?
A. Covalent bond
B. Paired bond
C. Metallic bond
D. Ionic bond
Answer:
D. Ionic bond
Explanation:
First some definitions: ionic bonds always have metals that transfer electrons. Covalent bonds are between nonmetals that share electrons. (Sharing is caring!)
Li is a metal, so right off the bat we know this is not a covalent bond. However, it's not a metal, so we can cross off C as well. The phrase "paired bond" isn't common, so we know the answer must be D. ionic bond.
And in this bond, Li's electrons will transfer to O to make both have a full valence shell. (As opposed to covalent bonds, which share electrons, not transfer completely.)
