13.

Explanation:

Step1: Balance the first equation

The reaction of glucose $\mathrm{C_6H_{12}O_6}$ with oxygen $\mathrm{O_2}$ is $\mathrm{C_6H_{12}O_6 + 6O_2
ightarrow6CO_2 + 6H_2O}$. The coefficients are 1, 6, 6, 6. The sum of the coefficients is $1 + 6+6 + 6=19$.

Step2: Balance the second equation

For the equation $\mathrm{C_2H_2+O_2
ightarrow CO_2 + H_2O}$, we balance it as $\mathrm{2C_2H_2+5O_2
ightarrow4CO_2 + 2H_2O}$. The coefficients are 2, 5, 4, 2. The sum of the coefficients is $2 + 5+4 + 2 = 13$.

First question: 19
Second question: 13
