Write the type of reaction on the lines below, then balance each equation by writing in a coefficient on the smaller lines. 1. underline ( )Ca(s)+underline ( )AlCl_(3)(aq)+underline ( )CaCl_(2)(aq)+underline ( )Al(s)

## Step 1<br />The given chemical equation is a redox reaction, which involves the transfer of electrons between two species. In this case, calcium (Ca) is being oxidized, meaning it is losing electrons, while aluminum (Al) is being reduced, meaning it is gaining electrons.<br /><br />## Step 2<br />To balance the chemical equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. This is in accordance with the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.<br /><br />## Step 3<br />Looking at the given equation, we can see that there is one calcium atom on both sides, three chlorine atoms on the left side and two on the right side, and one aluminum atom on both sides. Therefore, the equation is already balanced as written.
