Question

(i) Balance each of the chemical equations given below:
1. NaOH + H₂SO₄ → Na₂SO₄ + H₂O
2. Fe + H₂SO₄ → FeSO₄ + H₂

Answer 1

Explanation:

2nd wali equation pehle hi se balance h

Answer 2

Balance the equation

Explanation:

2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂O

On the left-hand side, we have:   2 Na, 6 O, 1 Sn and 4 H

On the right-hand side, we have: 2 Na, 6 O, 1 Sn and 4 H

The equation is balanced.

Fe + H₂SO₄ → FeSO₄ + H₂

On the left-hand side, we have:   2 H, 4 O, 1 S and 1 Fe

On the right-hand side, we have: 2 H, 4 O, 1 S and 1 Fe

The equation is already balanced, so there was no need to do anything further.
