Question

Balance the following equation stepwise.

NaOH + H₂SO₄ Na₂SO₄ + H₂O

Answer 1

Step 1) Write chemical equation

NaOH + H₂SO₄ → Na₂SO₄ + H₂O

Step 2) Compare number of atoms of each elements on each side.

Elements	Number of atoms on reactant side	Number of atoms on product side
Na	1	2
O	5	5
H	3	2
S	1	1

Step 3) Start balancing and write balanced equation.

Elements	Number of atoms on reactant side	Number of atoms on product side
Na	1	2
O	6	6
H	4	4
S	1	1

2NaOH + H₂SO₄ →Na₂SO₄ + 2H₂O
