Balance the given equation
1.H2+O2=H2O
2.fe+H2O=fe2O3+H2
Answers
Answer:2H2 + O2 = 2H2O
2 Fe+ 3 H2O→ Fe2O3 + 3H2
Answer:
1.
H2 + O2 = H2O
LHS RHS
H 2 2
O 2 1
Balancing oxygen
H2 + O2 = 2H2O
LHS RHS
H 2 4
O 2 2
Now balancing hydrogen
2H2 + O2 = 2H2O
LHS RHS
H 4 4
O 2 2
Hence, balanced
2.
Fe + H2O = Fe2O3 + H2
LHS RHS
Fe 1 2
H 2 2
O 1 3
Balancing iron
2Fe + H2O = Fe2O3 + H2
LHS RHS
Fe 2 2
H 2 2
O 1 3
Balancing oxygen
2Fe + 3H2O = Fe2O3 + H2
LHS RHS
Fe 2 2
H 6 2
O 3 3
Now, balancing hydrogen
2Fe + 3H2O = Fe2O3 + 3H2
LHS RHS
Fe 2 2
H 6 6
O 3 3
Hence, balanced
