Answer 1) Option D) 3 moles.
Explanation : In the reaction we can see that the number of moles of hydrogen are equal to the number of water molecules formed. Also, oxygen is found t o be the limiting reactant as equal number of moles are not produced in the reaction.
Here when we use 3 moles of hydrogen then 3 moles of water will be produced. As we are ignoring the moles of oxygen here as that is a limiting reactant.
Answer 2) Option A) 9 moles of reactants chemically change in to 11 moles of product.
Explanation : We can see that 1 mole of pentane reacts with 8 moles of oxygen to produce 5 moles of carbon dioxide and 6 moles of water. So when we add the reactants side we get 1 + 8 = 9 moles and in products it has 5 + 6 = 11 moles.
Hence, 9 moles of reactants produce 11 moles of products.
Answer 3) Option A) 0.62 moles.
Explanation : Here, the number of moles of Cu reacts with 2 moles of silver nitrate and gives 1 mole of copper nitrate and 2 moles of silver.
So, the ratio is 1 : 2 in the reactants side, Now, when we have 1.23 moles of silver nitrate then to calculate the number of Cu.
we can simply cross multiply and get the answer as 1.23 / 2 = 0.615 = ~ 0.62 moles.

Answer:
<h2>111.11 mL</h2>
Explanation:
Since the moles of gas and temperature are held constant the new volume can be found by using the formula for Boyle's law
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
From the question
P1 = 1 atm
P2 = 2.25 atm
V1 = 250 mL
We have
We have the final answer as
<h3>111.11 mL</h3>
Hope this helps you
