<u>Answer:</u> The correct answer is 4molH_2\times \frac{2molH_2O}{2molH_2}=4 molH_2O

<u>Explanation:</u>

We are given:

Moles of hydrogen gas = 4 moles

As, oxygen is given in excess. Thus, is considered as an excess reagent and hydrogen is considered as a limiting reagent because it limits the formation of products.

For the given chemical equation:

2H_2(g)+O_2(g)\rightarrow 2H_2O(l)

By Stoichiometry of the reaction:

2 moles of hydrogen produces 2 moles of water molecule.

So, 4 moles of hydrogen will produce = \frac{2molH_2O}{2molH_2}\times 4molH_2=4mol of water.

Hence, the correct answer is 4molH_2\times \frac{2molH_2O}{2molH_2}=4 molH_2O
