Question

Balance the following equation step wise

NaOH + H2SO4 ............... Na2SO4 + H2O

Answer 1

2NaOH + H2SO4 -------> Na2SO4 + 2H2O

Answer 2

NaOH + H₂SO₄ -----------> Na₂SO₄ + H₂O

Na -- 1(2) = 2                       Na -- 2

S -- 1                                     S -- 1

H-- 1(2) + 2   = 4                   H -- 2(2) = 4

O -- 1(2) + 4   =6                   O -- 4 + 1(2) = 6

Hence the balanced eq. is,

2 NaOH + H₂SO₄ --------> Na₂SO₄ + 2 H₂O

hope it helps
