- Burning of magnesium ribbon
Magnesium (Mg) + Oxygen (O 2 ) → Magnesium oxide (MgO) (burns with a bright light)
- Adding Water to Magnesium Oxide
Magnesium oxide (MgO) + Water (H 2 O) → Magnesium hydroxide [Mg(OH)2] (Magnesium Hydroxide is a base)
- Adding vinegar to baking soda
Vinegar (Acetic acid) + Baking soda (Sodium hydrogencarbonate) → Carbon dioxide + other substances
- Reaction of Copper sulphate with iron
Copper sulphate solution (blue) + Iron → Iron sulphate solution (green) + Copper (brown deposit)
- Reaction of carbon dioxide with lime water
Carbon dioxide (CO 2 ) + Lime water [Ca(OH)2] → Calcium Carbonate (CaCO 3 ) + Water (H 2 O)
