Question

complete following reactions.
Metal + Dilute acid = Salt + Hydrogen

Mg(s) + 2HCl(aq) = MgCl2(aq) 3 H2(g)

Zn (s) + .......... (aq) = ZnSO4 (aq) + .......

..... (s) + ...... (aq) Cu (NO), (aq) +H ​

Answer 1

Zn (s) + H2so4 (aq) = ZnSO4 (aq) + H2 (g)

Answer 2

Given:

Metal + Dilute acid = Salt + Hydrogen

$Mg(s)+ 2HCL(aq) = MgCl_{2} (aq)3H_{2} (g)$

$Zn (s) + H_{2} SO_{4}(aq) = ZnSO_{4}(aq) + H_{2} (g)$

$Cu(s)+NO_{3} (aq) Cu (NO), (aq) +H$

Hence above reactions are completed
