Question

How to balance
(1) H2+O2------>H2O
(2) NH3--------->H2 +N2
(3) Na2 SO4 + Ba(NO3)2------>BaSO4 + NaNO3
(4) Pb(NO3)2----------PbO+NO2+O2
(5) Fe2 O3 + CO -------->Fe + CO2

Answer 1

Answer:

(1) 2H2O + O2 ------> 2H2O

(2) 2NH3 ------>3H2 +N2

(3) Na2So4 +Ba(No3)2 ------> BaSo4 + 2NaNO3

(4) Pb(NO3)2----------PbO+NO2+O2 (It is already balanced)

(5) Fe2 O3 + CO -------->2Fe + 2CO2

Answer 2

Explanation:

1.2H2+O2----->2H2O

2.2NH3----->3H2+N2

3.NA2SO4+(BaNO3)2----->BaSO4+(NANO3)2

4.Pb(No3)2------>PbO+NO2+O2

5.Fe2O3 + 3CO----->Fe +3CO2
