Answer:
The balance chemical equation can be given as:
![ZnS(s)+ZnSO_4(aq)\overset{heat}\rightarrow 2Zn(s)+2SO_2(g)](https://img.qammunity.org/2020/formulas/chemistry/college/wha3z5vnyqoa10ko80xx6z98m4z8u0g90s.png)
Step-by-step explanation:
When zinc sulfide is allowed to react with zinc sulfate it gives zinc metal and sulfur dioxide gas as a product.The balance chemical equation can be given as:
![ZnS(s)+ZnSO_4(aq)\overset{heat}\rightarrow 2Zn(s)+2SO_2(g)](https://img.qammunity.org/2020/formulas/chemistry/college/wha3z5vnyqoa10ko80xx6z98m4z8u0g90s.png)
According to reaction we can see when 1 mol of zinc sulfide reacts with 1 mol of zinc sulfate it forms 2 moles of zinc metal and 2 moles of sulfur dioxide gas.
