Question

quiz : balancing chemical reactions
balance the following reaction. (enter the coefficients)
caco3 - cao + co2

Explanation:

Step1: Count atoms on both sides

Left side: 1 Ca, 1 C, 3 O. Right side: 1 Ca, 1 C, 3 O.

Step2: Check if balanced

Since the number of each atom (Ca, C, O) is the same on both sides, coefficients are 1 for each compound.

Answer:

1, 1, 1
