### Writing the Total Ionic Equation

**Instruction:**
Write the total ionic equation for the reaction below. Include states of matter, the charges on the ions and keep the equation balanced.

**Balanced Chemical Equation:**
\[ 2\text{Ni(NO}_3\text{)}_3\text{(aq)} + 3\text{K}_2\text{CO}_3\text{(aq)} \longrightarrow \text{Ni}_2\text{(CO}_3\text{)}_3\text{(s)} + 6\text{KNO}_3\text{(aq)} \]

### Steps to Write the Total Ionic Equation

1. **Dissociate all aqueous compounds into their respective ions.**

\[ 2\text{Ni(NO}_3\text{)}_3\text{(aq)} \rightarrow 2\text{Ni}^{3+}\text{(aq)} + 6\text{NO}_3^-\text{(aq)} \]
\[ 3\text{K}_2\text{CO}_3\text{(aq)} \rightarrow 6\text{K}^+\text{(aq)} + 3\text{CO}_3^{2-}\text{(aq)} \]
\[ \text{Ni}_2\text{(CO}_3\text{)}_3\text{(s)} \text{ does not dissociate as it is a solid.} \]
\[ 6\text{KNO}_3\text{(aq)} \rightarrow 6\text{K}^+\text{(aq)} + 6\text{NO}_3^-\text{(aq)} \]

2. **Combine all ions to write the total ionic equation.**

\[ 2\text{Ni}^{3+}\text{(aq)} + 6\text{NO}_3^-\text{(aq)} + 6\text{K}^+\text{(aq)} + 3\text{CO}_3^{2-}\text{(aq)} \longrightarrow \text{Ni}_2\text{(CO}_3\text{)}_3\text{(s)} + 6\text{K}^+\text{(aq)} + 6\text{NO}_3^-\text{(aq)}
