<u>Answer:</u> The coefficients are 2, 1 and 1

<u>Explanation:</u>

A balanced chemical equation always follow law of conservation of mass.

This law states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form. This also means that total number of individual atoms on reactant side must be equal to the total number of individual atoms on the product side.

The balanced chemical equation for the given reaction follows:

2Li+S\rightarrow Li_2S

By Stoichiometry of the reaction:

2 moles of lithium metal reacts with 1 mole of sulfur atom to produce 1 mole of lithium sulfide

Hence, the coefficients are 2, 1 and 1
