Answer:
<h2>2.44 L</h2>Explanation:
The volume can be used by using the formula for Boyle's law which is
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we're finding the final volume
We have
We have the final answer as
<h3>2.44 L</h3>Hope this helps you
<u>Answer:</u> The limiting reagent in the given chemical reaction is carbon metal.
<u>Explanation:</u>
Excess reagent is defined as the reagent which is present in large amount in a chemical reaction.
Limiting reagent is defined as the reagent which is present in small amount in a chemical reaction. Formation of product depends on the limiting reagent.
To calculate the number of moles, we use the equation:
.....(1)
Given mass of sodium sulfate = 16.29 g
Molar mass of sodium sulfate = 142 g/mol
Putting values in equation 1, we get:
Given mass of carbon = 3.697 g
Molar mass of carbon = 12 g/mol
Putting values in equation 1, we get:
For the given chemical reaction:
By Stoichiometry of the reaction:
4 moles of carbon reacts with 1 mole of sodium sulfate
So, 0.31 moles of carbon will react with = of sodium sulfate
As, given amount of sodium sulfate is more than the required amount. So, it is considered as an excess reagent.
Thus, carbon metal is considered as a limiting reagent because it limits the formation of product.
Hence, the limiting reagent in the given chemical reaction is carbon metal.
