Use the following word equation to write the balanced equation: calcium+nitrogenarrow calcium nitride __

## Step 1<br />The given word equation is "calcium + nitrogen → calcium nitride". This equation is not balanced because the number of atoms for each element is not the same on both sides of the equation.<br /><br />## Step 2<br />To balance the equation, we need to ensure that the number of atoms for each element is the same on both sides of the equation. In this case, we have one calcium atom and one nitrogen atom on the left side of the equation, and one calcium atom and one nitrogen atom on the right side of the equation.<br /><br />## Step 3<br />The balanced chemical equation for this reaction is "3Ca + N2 → 2Ca3N2". This equation is balanced because there are three calcium atoms and two nitrogen atoms on both sides of the equation.
