Answer #1

4. There will be no reaction between Zn(s) and MgSO4(aq). It is because, Mg is more reactive than zinc and also it has higher tendency to form dipositive ions than zinc.

5. Cu(s) does not react with H2SO4(aq). However, upon heating with concentrated H2SO4, the following reaction occurs.

Cu + 2H2SO4 = CuSO4 + SO2 + 2H2O

6. Zn(s) reacts with H2SO4(aq) according to the following equation.

Zn + H2SO4 = ZnSO4 +H2
