Question

Complete the following reactions:
1) Magnesium (Mg) +Oxygen(O) →
2) Vinegar+ Baking Soda →

3) Magnesium (MgO)+ Water (H2O) →

4) Copper Sulphate Solution (Blue) + Iron →
5) Iron (Fe) + Oxygen (O2 from air) + water(H2O) →
6) Carbon dioxide (CO2) + Lime Water (Ca(OH)2 →

Answer 1

1. Magnesium (Mg) + oxygen(O)⸻➤ MagnesiumOxide (MgO2).
2. Vinegar + Baking soda⸻➤ Sodium bicarbonate.
3. Magnesium (MgO)+ water(H2O)⸻➤Mg(OH)2.
4. CuSO4 + Fe ⸻➤FeSO4 + Cu.
5. Fe + O2 + H2O ⸻➤Fe2O3.
6. CO2 + Ca(OH)2 ⸻➤CaCO3 + H2
