Question

6CO2 + __H2O → C6H12O6 + 6O2

In order to balance the equation, what coefficient must be placed in front of H2O?

Answer 1

6 is the coefficient for h20
so we get 12 h

Answer 2

Explanation:

An equation that holds same number of atoms on both reactant and product side is known as a balanced chemical equation.

For example, $6CO_{2} + H_{2}O \rightarrow C_{6}H_{12}O_{6} + 6O_{2}$

Here, number of reactant atoms are as follows.

C = 6

O = 13

H = 2

Number of atoms on product side are as follows.

C = 6

O = 18

H = 12

Therefore, to balance this chemical equation we multiply $H_{2}O$ on reactant side by 6.

Hence, the balanced chemical reaction equation is as follows.

      $6CO_{2} + 6H_{2}O \rightarrow C_{6}H_{12}O_{6} + 6O_{2}$

Thus, we can conclude that in order to balance the equation, coefficient which must be placed in front of $H_{2}O$ is 6.
