Answer:
C6H1206 + 6O2 > 6CO2 + 6 H2O
Explanation:
On the left side we have 6xC so we multiply CO2 by 6 to get the same amount of C.
We have 12x H on the left side, so we multiply H2O on the right side by 6 to get the same amount of H.
On the right side we have 18x O ( 6CO2 gives us 6x2x O which is 12O; and 6H2O gives us 6O. To get the same amount on the left side ( we already have 6O in C6H12O6), so we only need 12 O more. So we multiply O2 on the left side by 6. Which gives us 18x O on both sides.
So on both sides we have now:
6x C
12xH
18xO
