Question

balance. the. equation. CO2+H2O=C6H12O6+O2+H2O

Answer 1

6CO2+12H2O=C6H12O6 +6O2+6H20

Answer 2

The balancing of any chemical reaction involves certain steps:

1. Write the chemical equation:  

$\mathrm{CO}_{2}+\mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}+\mathrm{O}_{2}$

2. Balance C atoms:

$6 \mathrm{CO}_{2}+\mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}+\mathrm{O}_{2}$

3. Balance H atoms:  

$6 \mathrm{CO}_{2}+6 \mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}+\mathrm{O}_{2}$

4. Balance O atoms:

$6 \mathrm{CO}_{2}+6 \mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}+\mathrm{O}_{2}+6 \mathrm{O}_{2}$

5. Overall balance chemical equation will be:

$6 \mathrm{CO}_{2}+6 \mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}+\mathrm{O}_{2}$

Hence always check all atoms at both sides of the chemical equation that must be same in a balance the number of molecules in reactants and products in chemical equation.
