Question

Copper(i) sulfide (cu2s) is synthesized in a reaction described by this chemical equation: 2cu(s) + s(s) → cu2s(s) a ratio of 2:1 applies to the _____ that enter into the reaction.

Answer 1

The answer is the number of atoms that enter into the reaction.

Answer 2

Explanation:

The given reaction is as follows.

  $2Cu(s) + S(s) \rightarrow Cu_{2}S(s)$

In this reaction, there are 2 atoms of copper and one atom of sulfur are reacting with each other and result in the formation of copper(I) sulfide.

Therefore, we can conclude that there is a ratio of 2:1 applies to the number of reactant atoms that enter into the reaction.
