Question

Complete the following chemical reaction and balanced the chemical equation:

(i) Mg + HCl
(ii) NaOH + Zn
(iii) HCl + Na2CO3​

Answer 1

Chemical equations:

• Mg + HCl → MgCl₂ + H₂

• NaOH + Zn → Na₂ZnO₂ + H₂

• HCl + Na₂CO₃ → NaCl + CO₂ + H₂O

Balanced Equations:

• Mg + 2HCl → MgCl₂ + H₂

• 2NaOH + Zn → Na₂ZnO₂ + H₂

• 2HCl + Na₂CO₃ → 2NaCl + CO₂ + H₂O

━━━━━━━━━━━

Answer 2

Answer:

(i) Mg + 2HCl = MgCl2 + H2 (gas released)

(ii)2NaOH + Zn = Na2ZnO2 + H2 (gas released)

(iii) 2HCl + Na2CO3 = 2NaCl + CO2+ H2O
