Question

I. Write the balanced chemical equations for the following word equations:

1. Calcium carbonate → calcium oxide + carbon dioxide

2. Sodium + chlorine → sodium chloride

3. Sodium + Water → Sodium hydroxide + Hydrogen

4. Barium chloride + Aluminium sulphate → Barium sulphate + Aluminium chloride

5. Calcium Oxide (Quick Lime) + Water → Calcium Hydroxide (Slaked Lime)

6. Zinc + Silver nitrate → Zinc nitrate + Silver

7. Potassium bromide (aq) + Barium iodide(aq) → Potassium iodide (aq) + Barium

bromide(s)

8. Zinc carbonate (s) → Zinc oxide (s) + Carbon dioxide (g)

9. Hydrogen (g) + Chlorine (g) → Hydrogen chloride (g)

10. Magnesium (s) + Hydrochloric acid (aq) → Magnesium chloride(aq)​

Answer 1

answer is..

1) CaCO3 → CaO + CO2 2) Na + Cl2 → NaCl 3) Na + H2O →NaOH + H2 4) BaCl2 + Al2 (NO3)2 → BaSO4 +AlCl3 5) CaO + H2O → Ca (OH)2 6) Zn + AgNO3→ Zn (NO3)2 + Ag 7) KBr + Bal2→ KI + BaBr2 8) ZnCO3 → ZnO + CO2 9) H2 + Cl2 → HCl 10) Mg + HCl → MgCl2 hope it help u ☆★☆
