Question

balance the chemical equation. with steps
CO2+H2O= C6H12O6+O2+H2O​

Answer 1

Answer:

These must be obtained from half that number of molecules of H2O. Finally, one must have sufficient oxygen molecules produced to balance the number of oxygen atoms present in the reactants. So, overall: 6CO2(g) + 6H2O(l) > C6H12O6(aq) + 6O2(g).

Answer 2

Answer:

$\bold{6CO_2+7H_2O \to C_6H_{12}O_6+6O_2+H_2O}$

Explanation:

Always try to start with an element other than Hydrogen or Oxygen. In this case, we can start with Carbon. Since there are 6 Carbons on the right hand side of the arrow($\to$), we need six Carbons on the left hand side. $6CO_2 + H_2O \to C_6H_{12}O_6 + O_2 + H_2O$.

Next, look at the Hydrogen: 2 on the left hand side and 14 on the right hand side. We need 14 on the left hand side: $6 CO_2 + 7 H_2O \to C_6H_{12}O_6 + O_2 + H_2O$

Now check the Oxygen: 19 on the left hand side and 9 on the right hand side. We need 19 on the right so we put in a coefficient of 6 in front of the $O_2$:

$6 CO_2 + 7 H_2O \to C_6H_{12}O_6 + 6 O_2 + H_2O$
