Question

Complete the following chemical equations and balance them [10]

1. Ca+ H2O ----------- + H2

2. AgCl Ag(s) +-----------

3. CuO +--------- CuSO4 +H2O

4. BaCl2 + -------- BaSO4+ NaCl

5. Cl2(g) + KBr(aq) --------+ Br2(g).​

Answer 1

Explanation:

1. 2Ca + 2H2O --- 2CaO + 2H2

2. 2AgCl --- 2Ag + Cl2

3. CuO + H2So4 --- CuSo4 + H2O (It is already balanced.)

4. BaCl2 + Na2So4 --- BaSo4 + 2NaCl

5. Cl2 + 2KBr --- 2KCl + Br2
