Answer 2

Decomposition reactions involve breaking down a compound into its simpler components. Let's balance the decomposition reactions for sodium chloride (NaCl) and nickel(III) oxide (Ni₂O₃).

1. **Decomposition of Sodium Chloride (NaCl)**:
Sodium chloride doesn’t usually decompose under standard conditions but can be decomposed under very high temperatures or electrolysis into its elemental components:
\[ 2 \, \text{NaCl} \rightarrow 2 \, \text{Na} + \text{Cl}_2 \]

2. **Decomposition of Nickel(III) Oxide (Ni₂O₃)**:
Nickel(III) oxide usually decomposes at high temperatures to yield nickel and oxygen:
\[ 4 \, \text{Ni}_2\text{O}_3 \rightarrow 4 \, \text{Ni} + 3 \, \text{O}_2 \]

So, the balanced equations for the decomposition reactions are:

1. **Sodium Chloride**:
\[ 2 \, \text{NaCl} \rightarrow 2 \, \text{Na} + \text{Cl}_2 \]

2. **Nickel(III) Oxide**:
\[ 4 \, \text{Ni}_2\text{O}_3 \rightarrow 4 \, \text{Ni} + 3 \, \text{O}_2 \]
