How many grams of oxygen are required to produce
9 grams of water at standard conditions?
2 H, + 0, → 2H20
grams
Answer:
4g
Explanation:
Equation of reaction
2H₂ + O₂ → 2H₂O
Molar mass of O2 = 16g/mol
Molar mass of water = 18g/mol
Number of moles = mass / molar mass
Mass = molar mass × number of moles
Mass of O2 = 1 × 16 = 16g
Mass of H2O = 2 × 18 = 36g
So from equation of reaction,
16g of O2 = 36g of H2O
X of O2 = 9g of H2O
X = (9 × 16) / 36
X = 4g
4g of O2 will produce 9g of H2O

C) liquid sodium or water
D) CFCs
3. A reaction that results in the combining of smaller atomic nuclei is ___.

D) ionization
4. What does neutron absorption accomplish in a nuclear reactor?
A) It slows down the reaction.
B) It speeds up the reaction
C) It increases the rate of heat absorption
D) It recycles the fuel
Answer:
C B A D
Explanation:
1. A) Products that start a new reaction are released.
2. C) liquid sodium or water
3. C) fusion
4. B) It speeds up the reaction.
1. In a chain reaction, the products of one reaction are capable of initiating further reactions. Specifically, in a nuclear chain reaction, the fission of a heavy nucleus (such as uranium-235) releases neutrons, which can then go on to cause the fission of other nuclei. This is a self-sustaining series of reactions where the products (neutrons) start new reactions. Hence, option A is correct.
2. Nuclear reactors can use different types of coolants to transfer the heat generated by the nuclear reactions to the turbines or to the environment. The most common coolants are water (in light-water reactors) and liquid sodium (in fast-breeder reactors). Therefore, option C, which states liquid sodium or water, is the correct answer.
3. A reaction where smaller atomic nuclei combine to form a heavier nucleus is known as fusion. This is different from fission, which is the splitting of a heavy nucleus into smaller nuclei. Chemical reactions involve the rearrangement of electrons in atoms or molecules, not the combining or splitting of atomic nuclei. Ionization is the process of adding or removing charged particles to or from an atom or molecule, but it does not involve the combining or splitting of nuclei. Thus, the correct answer is option C, fusion.
4. Neutron absorption is a critical part of the operation of a nuclear reactor. When a neutron is absorbed by a fissile nucleus (like uranium-235), it can cause that nucleus to become unstable and split, releasing energy and more neutrons. This process is what sustains the chain reaction in a nuclear reactor. The absorption of neutrons by fissile material effectively speeds up the reaction by increasing the rate of fission events. Therefore, option B, It speeds up the reaction, is the correct answer."

Explain why potassium chloride has the formula KCl, but potassium oxide is K2O (5)
Answer:
This has to do with the charge. The charge of K is +1. The charge of Cl is -1. I like to use a method called the criss cross method. So K+1 and Cl-1. I give each number to the other atom. (the "1" in Cl-1 goes to K the "1" in K+1 goes to Cl) so it becomes K1Cl1 which is KCl. Oxygen has a charge of 2-, so the 2 goes to the K and the 1 in K goes to the O, so it becomes K2O. Dm me if you want further explanation.
Explanation:
Final answer:
Potassium chloride consists of potassium and chloride ions, each with a 1+ and 1- charge, respectively, forming the formula KCl. Potassium oxide requires two potassium ions to balance the 2- charge of the oxide ion, resulting in the formula K₂O.
Explanation:
The reason why potassium chloride has the formula KCl but potassium oxide has the formula K₂O is based on the charges of the ions each metal and nonmetal forms. Potassium (K) forms a cation with a 1+ charge, while chloride (Cl) forms an anion with a 1- charge. To balance the charges, one potassium ion will pair with one chloride ion, resulting in the formula KCl, which has a neutral overall charge.
On the other hand, oxygen (O) forms an oxide anion with a 2- charge. To balance the charges, two potassium ions with a 1+ charge each are needed for every one oxide ion. This results in the chemical formula K₂O, as the two potassium ions balance out the charge of the one oxide ion, making the overall compound electrically neutral.
What determines the amount of kinetic energy that an object has?
Answer:
The mass (M) and speed of an object (v)
Explanation:
Final answer:
The amount of kinetic energy an object has is determined by its mass and velocity, governed by the equation KE = 1/2mv², indicating that energy increases with mass and quadruples with a doubling of velocity.
Explanation:
What Determines the Amount of Kinetic Energy an Object Has?
The amount of kinetic energy that an object possesses is determined by two primary factors: the mass of the object and its velocity. According to the principles of classical mechanics, the kinetic energy (KE) is given by the equation KE = 1/2mv², where m represents mass and v represents velocity. Thus, the kinetic energy increases with a higher mass and increases dramatically with a higher velocity, as the velocity is squared in the equation. For example, a heavy truck moving at a certain speed has more kinetic energy than a smaller car moving at the same speed because the truck has a greater mass. Additionally, if an object's speed is doubled, its kinetic energy increases by a factor of four, not two, demonstrating that kinetic energy is more sensitive to changes in velocity than to changes in mass.
The above shows a balloon full of gas which has a volume of 120.0 mL
at 300.0 K. Assuming pressure remains constant, what is the volume
of the balloon if the temperature of the gas increases to 320,0 K?
mL
Your answer should be rounded to three significant figures. Do not include units in your
answer.
Answer: 128 mL
Explanation: 120mL/300k=v2/320k
The new volume of the balloon when the temperature increases from 300.0 K to 320.0 K, while keeping pressure constant, is 128.0 mL.
The original question asks for the new volume of a balloon filled with gas when the temperature is increased from 300.0 K to 320.0 K, assuming pressure remains constant. This is a direct application of Charles's Law, which states that at constant pressure, the volume of a fixed amount of gas is directly proportional to its temperature in Kelvin. The formula for Charles's Law is V₁/T₁ = V₂/T₂, where V₁ and T₁ are the initial volume and temperature, and V₂ and T₂ are the final volume and temperature, respectively.
To solve for V₂, we rearrange the formula to V₂ = V₁ × (T₂/T₁). Plugging in the values:
V₁ = 120.0 mL (initial volume)
T₁ = 300.0 K (initial temperature)
T₂ = 320.0 K (final temperature)
So, V₂ = 120.0 mL × (320.0 K / 300.0 K)
V₂ = 120.0 mL × (1.0667)
V₂ = 128.0 mL when rounded to three significant figures.

A sailor pulls a boat along a dock using a rope. How much work does the sailor do if he exerts a force of 255 N on the rope and pulls the boat 11.4 m?
Answer:
The work done is 2,907 J
Explanation:
Work is one of the forms of energy transmission between bodies. To perform a job, you must exert a force on a body and it moves. In other words, when a force is applied to a body and it moves, work is done.
The work is equal to the product of the force by the distance and by the cosine of the angle that exists between the direction of the force and the direction that the moving point or object travels:
W = F * d * cos α
In the International System of Units the Force is expressed in newtons and the distance in meters, so the work will have units of newtons. Meter = joules (J).
In this case:
F= 255 Nd= 11.4 mα=0Replacing:
W= 255 N* 11.4 m* cos 0
Solving:
W= 255 N* 11.4 m* 1
W= 2,907 J
The work done is 2,907 J
The work done by the sailor is 2907 joules (J).
To calculate the work done by the sailor, we can use the formula for work:
[tex]\[\text{Work} = \text{Force} \times \text{Distance} \times \cos(\theta)\][/tex]
where:
- [tex]\(\text{Force}\)[/tex] is the force exerted by the sailor,
- [tex]\(\text{Distance}\)[/tex] is the distance over which the force is applied,
- [tex]\(\theta\)[/tex] is the angle between the force and the direction of movement.
If the force is applied in the direction of the movement, [tex]\(\theta = 0\)[/tex] degrees and [tex]\(\cos(0) = 1\)[/tex].
Given:
- [tex]\(\text{Force} = 255 \, \text{N}\)[/tex]
- [tex]\(\text{Distance} = 11.4 \, \text{m}\)[/tex]
- [tex]\(\theta = 0\)[/tex] degrees (assuming the force is in the direction of the movement)
Substitute these values into the formula:
[tex]\[\text{Work} = 255 \, \text{N} \times 11.4 \, \text{m} \times \cos(0)\][/tex]
[tex]\[\text{Work} = 255 \, \text{N} \times 11.4 \, \text{m} \times 1\][/tex]
[tex]\[\text{Work} = 2907 \, \text{J}\][/tex]

Final answer:
If PCl5 is removed from the equilibrium PCl5(g) = PCl3(g) + Cl2(g), the equilibrium will shift to the left to replace the removed PCl5, according to Le Châtelier's Principle.
Explanation:
Using the equation PCl5(g) = PCl3(g) + Cl2(g), if PCl5 is removed, the equilibrium will shift toward the left to replace the removed PCl5. This is because, according to Le Châtelier's Principle, when a component of a reaction at equilibrium is removed, the equilibrium will shift in the direction that tends to replace that component. In this reaction, removing PCl5 decreases its concentration, thus the system shifts left to increase its concentration by converting PCl3 and Cl2 back into PCl5.
If 16.00 g of O₂ reacts with 80.00 g NO, what is the excess reactant? *
A.O₂
B.NO
Answer:
B. NO
Explanation:
In each mole of NO, the weight of the oxygen is 16.00 g; the weight of the nitrogen is 14.01 g. Then in 80 g of NO, we have 42.65 g of oxygen and 37.35 g of nitrogen.
__
In each mole of NO₂, the weight of the oxygen is 2(16.00) = 32 g. The weight of the nitrogen is 1(14.01) = 14.01 g.
From the available oxygen, we can produce ...
(42.65 g +16 g)/(32.00 g/mol) = 1.83 mol of NO₂
From the available nitrogen, we can produce ...
(37.35 g)/(14.01 g/mol) = 2.67 mol of NO₂
Clearly, the reaction is limited by the amount of available oxygen.

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.)
The pressure of nitrogen gas at 35°C is changed from 0.89 atm to 4.3 atm. What will be its final temperature in Kelvin?
Answer: The final temperature in Kelvin is 1488
Explanation:
To calculate the final temperature of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
[tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}[/tex]
where,
[tex]P_1\text{ and }T_1[/tex] are the initial pressure and temperature of the gas.
[tex]P_2\text{ and }T_2[/tex] are the final pressure and temperature of the gas.
We are given:
[tex]P_1=0.89atm\\T_1=35^0C=(35+273)K=308K\\P_2=4.3atm\\T_2=?[/tex]
Putting values in above equation, we get:
[tex]\frac{0.89}{308}=\frac{4.3}{T_2}\\\\T_2=1488K[/tex]
Hence, the final temperature in Kelvin is 1488
Why do the words “Shake well before using” indicate that the fruit juice in a carton is a suspension? What are these words not used on a milk container?
Answer:
It indicates it is a suspension b/c in a suspension heavy particles separate or fall and the ingredie-nts would need to be mixed after sinking.
and for the milk one I'm not sure but I think when u shake milk well it may change into a butter.
Because some of the larger particles in a suspension will eventually settle out.
What are suspensions?Suspensions are defined as a mixture that is heterogeneous, meaning the solid particles are dispersed throughout the liquid without really dissolving in it. The friction between the tires of your car and the pavement is increased by suspension systems. It is possible to steer your car more steadily and enjoy more comfortable handling by increasing friction. You can drive more securely and safely the more contact your tires have with the road.
The fact that the ingredients would need to be mixed after sinking suggests that it is a suspension. For the milk one, I'm not sure, but I believe that when milk is shaken thoroughly, it may transform into butter.

How many atoms are present in 55 grams of iron
To find the number of atoms present in 55 grams of iron, we need to convert grams to moles and then use Avogadro's number to convert moles to atoms.
Explanation:To find the number of atoms present in 55 grams of iron, we need to convert grams to moles and then use Avogadro's number to convert moles to atoms. The molar mass of iron is 55.8 g/mol. Therefore, 55 grams of iron is equal to:
55 g / 55.8 g/mol = 0.986 moles of iron.
Since 1 mole of any substance contains Avogadro's number (6.022 x 10^23) of particles, the number of atoms in 0.986 moles of iron is:
0.986 mol x (6.022 x 10^23 atoms/mol) = 5.93 x 10^23 atoms of iron.

There are [tex]$\boxed{1.20 \times 10^{24}}$[/tex] atoms of iron present in 55 grams of iron.
To determine the number of atoms in 55 grams of iron, we follow these steps:
1. First, we need to know the molar mass of iron. The molar mass of iron (Fe) is approximately 55.845 grams per mole.
2. Next, we use Avogadro's number, which is [tex]$6.022 \times 10^{23}$[/tex] atoms per mole, to find the number of atoms in one mole of iron.
3. Now, we calculate the number of moles in 55 grams of iron by dividing the mass of iron by its molar mass:
[tex]\[ \text{moles of iron} = \frac{\text{mass of iron}}{\text{molar mass of iron}} = \frac{55 \text{ g}}{55.845 \text{ g/mol}} \approx 1 \text{ mol} \][/tex]
4. Finally, we multiply the number of moles by Avogadro's number to find the total number of atoms:
[tex]\[ \text{number of atoms} = \text{moles of iron} \times \text{Avogadro's number} \] \[ \text{number of atoms} \approx 1 \text{ mol} \times 6.022 \times 10^{23} \text{ atoms/mol} \] \[ \text{number of atoms} \approx 6.022 \times 10^{23} \text{ atoms} \][/tex]
Since we have approximately 1 mole of iron, the number of atoms is approximately equal to Avogadro's number. Therefore, there are approximately [tex]$1.20 \times 10^{24}$[/tex] atoms of iron in 55 grams of iron, considering the minor rounding in the molar mass.
