<h2>Answer:</h2>
6.67moles
<h2>Explanations:</h2>
Given the balanced chemical reaction between hydrogen and oxygen expressed as:

First, you need to calculate the moles of water produced.

Based on stochiometry, 2 moles of hydrogen produces 2 moles of water, hence the moles of hydrogen that will be needed to produce 120g of water is 6.67moles

Answer : The balanced chemical reaction will be:

Explanation :
Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.
As per given statement, the sodium reacts with sulfur to form sodium sulfide as a product.
The balanced chemical reaction will be:

By the stoichiometry we can say that, 16 moles of Na react with 1 mole of
to give 8 moles of
.
