Explanation:

Step1: Analyze \( \text{Zn}(\text{C}_2\text{H}_3\text{O}_2)_2 \)

In \( \text{Zn}(\text{C}_2\text{H}_3\text{O}_2)_2 \), the subscript of \( \text{C} \) in the parentheses is 2, and the outer subscript is 2. So carbon atoms here: \( 2\times2 = 4 \).

Step2: Analyze \( \text{K}_2\text{CO}_3 \)

In \( \text{K}_2\text{CO}_3 \), the subscript of \( \text{C} \) is 1, so carbon atoms here: \( 1 \).

Step3: Sum the carbon atoms

Total carbon atoms on the left side: \( 4 + 1 = 5 \).

Answer:

5
