Then balance the chemical equation of each of the following.
1. iron[iii] oxide ——>copper [ii] oxide
2. Sodium + Water ——> Sodium Hydroxide + Hydrogen
3. Copper + Oxygen ——> Copper [ II ] Oxide
4. Potassium Iodide + chlorine ——> potassium chloride + iodine
5. Magnesium Copper [ ii ] sulphate ——> Magnesium sulphate + Copper ​

Answer 1

Answer:

Explanation:

1. Iron (iii) oxide -----> copper (ii) oxide

Ans: This is an incomplete equation. Please give all the reactants and products

2. Sodium + water -----> Sodium hydroxide + hydrogen

Ans: 2Na + 2H2O -----------> 2NaOH + H2

3. Copper + oxygen --------> Copper (II) oxide

Ans: 2Cu + O2 ---------> 2CuO

4. Potassium Iodide+ chlorine -------> potassium chloride + iodine

Ans: 2KI + 2Cl -----------> 2KCl + I2

5. Magnesium +  Copper (ii) sulphate -------> Magnesium sulphate + Copper

Ans: Mg + CuSO4 ----------> MgSO4 + Cu

Hope this helps.
