Balancing Chemical Equations and Identifying Reaction Types

Let's balance the given chemical equations and identify the types of reactions involved.

1. NaNO3 → NaNO2 + O2

To balance this equation, we need to ensure that the number of atoms on both sides of the equation is equal. Here's the balanced equation:

2 NaNO3 → 2 NaNO2 + O2

The type of reaction here is decomposition, as a single compound (NaNO3) breaks down into two or more simpler substances (NaNO2 and O2).

2. Ca + C → CaC2

To balance this equation, we need to ensure that the number of atoms on both sides of the equation is equal. Here's the balanced equation:

Ca + C → CaC2

The type of reaction here is synthesis, as two or more substances combine to form a single compound.

3. Al + H2(SO4) → Al2(SO4)3 + H2

To balance this equation, we need to ensure that the number of atoms on both sides of the equation is equal. Here's the balanced equation:

2 Al + 3 H2(SO4) → Al2(SO4)3 + 3 H2

The type of reaction here is double displacement, as the cations and anions of two compounds exchange places to form new compounds.
