Question

2. Balance the following equations :
(i) Mg(s) + N2(g) →→ Mg3N2(s)
(ii) ZnCO3(s) + HNO3(aq)
+ HNO3(aq) →→ Zn(NO3)2(aq) +
(iii) Cu(NO3)2(5)
-→ Cuo(s) + NO2(g) + O2(g)
(iv) Al(OH)3(s) + H2SO4(aq) + Al(SO4)3(aq)
(v) Cu(s) +H2SO4 (aq) - → CuSO4(aq) + H2O

Answer 1

(i)Mg(s) + N2(g) →→ Mg3N2(s)

3Mg(s) + N2(g) → Mg3N2(s)

(ii) ZnCO3(s)+ HNO3(aq)+ HNO3(aq) →→ Zn(NO3)2(aq)
