Question

4.0 mol Na2S reacts with 5.0 mol
CuSO4 according to the equation below:
Na₂S + CuSO4 → Na₂SO4 + CuS

How many moles of Na2SO4 form from 5.0 moles of CuSO4?

[?] mol Na₂SO4
Round your answer to the tenths place.

Answer 1

The number of moles of $Na_2SO_4$ form from 5.0 moles $Na_2S$ is 5 moles.

What is a limiting reactant?

Limiting reactants are those reactants that are completely used up in a chemical reaction.

4.0 mol $Na_2S$ will be completely used since the combining ratio is 1 : 1 : 1.

$Na_2S + CuSO_4$ ->$Na_2SO_4 + CuS$

From the chemical equation above, 5.0 moles $Na_2S$ will yield 5 moles of $Na_2SO_4$.
