Balance this equation. underline ( )Mg+underline ( )Cl_(2)arrow underline ( )MgCl_(2) 1.2.1 1.1.2 already balanced 2,1,1

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.<br /><br />Given equation: $\underline {\quad }Mg+\underline {\quad }Cl_{2}\rightarrow \underline {\quad }MgCl_{2}$<br /><br />Step 1: Count the number of atoms of each element on both sides of the equation.<br />- On the left side: 1 Mg atom and 2 Cl atoms<br />- On the right side: 1 Mg atom and 2 Cl atoms<br /><br />Step 2: Balance the equation by adjusting the coefficients.<br />- The number of Mg atoms is already balanced (1 Mg atom on both sides).<br />- The number of Cl atoms is also balanced (2 Cl atoms on both sides).<br /><br />Therefore, the balanced equation is:<br />$1Mg + 1Cl_{2} \rightarrow 1MgCl_{2}$<br /><br />Answer: $1, 1, 1$
