Question

Consider the balanced equation below.

Answer 1

Answer : The correct option is, (2) 8 mole of hydrogen will react with 1 mole of sulfur.

Explanation :

The balanced chemical equation is,

$8H_2+S_8\rightarrow 8H_2S$

By the stoichiometry we conclude that, 8 moles of hydrogen react with 1 mole of sulfur to give 8 moles of hydrogen sulfide.

Hence, the correct options is, (2) 8 mole of hydrogen will react with 1 mole of sulfur.

Answer 2

The balanced reaction shows 8 moles of hydrogen gas, H2, reacts with 1 mole of molecular sulfur, S8. The most likely prediction is the second answer, 8 mol of hydrogen will react with 1 mol of sulfur.
