Answer 1

HEY mate here is your answer.

hope it helps you.

Answer 2

Answer: The amount of R produced is 4 moles

Explanation:

We are given a chemical equation:

$2P+Q\rightarrow R$

By Stoichiometry of the reaction:

2 moles of P reacts with 1 mole of Q.

So, 8 moles of P will react with = $\frac{1}{2}\times 8=4$ moles of Q.

As, the given amount of Q is more than the required amount. So, it is present in excess. Thus, it is considered as an excess reagent.

P is considered as a limiting reagent because it limits the formation of product.

By Stoichiometry of the reaction:

2 moles of P produces 1 mole of R

So, 8 moles of P will produce = $\frac{1}{2}\times 8=4$ moles of R.

Hence, the amount of R produced will be 4 moles.
