The chemical equation without coefficients is:

Ca + CO2 + O2 --------> Ca CO3

You can balance that equation by trial an error.

This is the chemical equation balanced:

2Ca + 2CO2 + O2 --------> 2Ca CO3

Count the atoms on each side to check the balance

Atom Left side    right side

Ca    2    2

C    2    2

O 2*2 + 2 = 6    2*3 = 6

Then those are the coefficients:

a0 = 2

a1 = 2

a2 = 1

a3 = 2
