CBSE - Chemistry - Chemical Reactions and Equations

Balance the following chemical equations.

(i) HNO₃ + Ca(OH)₂ → Ca(NO₃)₂ + H₂O
(ii) NaOH + H₂SO₄ → Na₂SO₄ + H₂O
(iii) NaCl + AgNO₃ → AgCl + NaNO₃
(iv) BaCl₂ + H₂SO₄ → BaSO₄ + HCl

Answer

(i) 2HNO₃ + Ca(OH)₂ → Ca(NO₃)₂ + 2H₂O
(ii) 2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂O
(iii) NaCl + AgNO₃ → AgCl + NaNO₃
(iv) BaCl₂ + H₂SO₄ → BaSO₄ + 2HCl
