Question

(a) Balance the following important equation-
(i) Fe2O3 + AI
Al2O3 + Fe
(ii) Pb(NO3)2 + HCI-
PbCl2 + HNO3
(iii) S + H2S04-
SO2 + H20
(iv) MnO2 + HCH
MnCl2 + H2O + Cl2
(v) NH3 + O2
N2 + H2O​

Answer 1

Explanation:

Fe2O3 + 2Al = Al2 O3 + 2Fe

Pb(NO3)2 + 2HCl = PbCl2 + 2HNO3

S + 2 H2SO4 = 3SO2 + 2H2O

MnO2 + 4HCl = MnCl2 + H2O + Cl2

4NH3 + 3O2 = 2N2 + 6H20

Answer 2

Answer:

i) Fe2O3 +2AI------->Al2O3 +2 Fe

(ii) Pb(NO3)2 + 2HCI-------->PbCl2 + 2HNO3

(iii) S + 2H2S04------->3SO2 + 2H20

(iv) MnO2 +4HCl------->MnCl2 + H2O + Cl2

hope this is the question u asked

(v) 4NH3 + 3O2---->2N2 + 6H2O
