Question

Balance the following chemical reactions:(a) Ca(OH)2 + HNO3 ⎯→ Ca(NO3)2 + H2O(b) BaCl2 (aq) + H2SO4 (aq) ⎯→ BaSO4 (s) + HCl (aq)(c) CuSO4 (aq) + Zn (s) ⎯→ ZnSO4 (aq) + Cu (s)(d) H2S (g) + SO2 (g) ⎯→ S (s) + H2O (l)(e) BaCl2 (aq) + Al2(SO4)3 (aq) ⎯→ AlCl3 (aq) + BaSO4 (s)(f) Pb (NO3)2 (aq) + Fe2(SO4) (aq) ⎯→ Fe(NO3)3 (aq) + PbSO4 (s)(g) Calcium hydroxide + carbon dioxide ⎯→ Calcium carbonate + water(h) Aluminium + Copper (II) chloride ⎯→ Aluminium chloride + copper(i) Calcium carbonate + hydrochloric acid ⎯→ Calcium chloride + water + carbon dioxide

Answer 1

(a) 2(HNO3) + Ca(OH)2 → Ca(NO3)2 + 2(H2O)

(b) 2(NaOH) + (H2SO4) → (Na2SO4) + 2(H2O)

(c) (NaCl) + (AgNO3) → (AgCl) + (NaNO3)

it is balanced.

(d) (BaCl2) + (H2SO4) → (BaSO4) + 2(HCl)
