Question

(h) Balance the following equations:
(i) NaCl + MnO2 + H2SO4 → NaHSO, + Mnso, + H2O + CI,
(ii) FeSO, + NaOH-
→ Na2SO4 + Fe(OH)
(iii) HgO(s) -> Hg(1) + O2(g)
(iv) PbO + HNO3 → Pb(NO3)2 + H20
(V) MnO2 + HCI
→ MnCl2 + H2O + Cl2​

Answer 1

Answer:

Explanation:

i)2 NaCl + MnO2 + H2SO4 →2 NaHSO2 + Mnso2 +2 H2O + CI2

(ii) FeSO4 + NaOH- → Na2SO4 + Fe(OH)

(iii) 2HgO(s) ->2 Hg(1) + O2(g)

(iv) PbO +2 HNO3 → Pb(NO3)2 + H20

(V) MnO2 +2 HCI → MnCl2 + 2H2O + Cl2​

Answer 2

Explanation:

iii)2Hgo->2Hgo+o2

v)Mno2+4hcl_>Mncl2+2H2o+cl2
