Balance the following reaction A coefficient of "I"is understood. Choose option "blank" for the correct answer if the coefficient is "1." +Zn+ +AClarrow AZCl_(2)+

To balance the chemical equation, we need to ensure that the number of each type of atom is the same on both sides of the equation. The given reaction is:<br /><br />\[ \_ \text{Zn} + \_ \text{ACl} \rightarrow \_ \text{AZCl}_2 + \_ \]<br /><br />Let's assume "A" represents a generic element. The balanced equation should have the same number of Zn, A, and Cl atoms on both sides.<br /><br />1. **Balance Zn:** <br /> There is 1 Zn atom on the right side in AZCl\(_2\), so we need 1 Zn atom on the left side. <br /> Coefficient for Zn: 1 (blank)<br /><br />2. **Balance A:** <br /> There is 1 A atom on the right side in AZCl\(_2\), so we need 1 A atom on the left side. <br /> Coefficient for ACl: 1 (blank)<br /><br />3. **Balance Cl:** <br /> There are 2 Cl atoms on the right side in AZCl\(_2\), so we need 2 Cl atoms on the left side. <br /> Coefficient for ACl: 2<br /><br />The balanced equation is:<br /><br />\[ \text{Zn} + 2 \text{ACl} \rightarrow \text{AZCl}_2 \]<br /><br />So, the coefficients are:<br />- Zn: blank (1)<br />- ACl: 2<br />- AZCl\(_2\): blank (1)
