Question

Fill in the coefficients that will balance the following reaction: a0C8H18 + a1O2 → a2CO2 + a3H2O

Answer 1

The answer is 2, 25, 16, 18 <

Answer 2

Answer: $a_0$=2,$a_1$=25,$a_2$=16, $a_3$=18

Explanation:This is an oxidation reaction in which alkane $C_nH_{2n+2}$ is getting oxidised to give carbon dioxide and water.

$a_0C_8H_18+a_1O_2\rightarrow a_2CO_2+a_3H_2O$

$2C_8H_18+25O_2\rightarrow 16CO_2+18H_2O$

According to the law of conservation of mass, the number of atoms on product side must be equal to the number of atoms on reactant side so s the mass remains conserved.

Thus $a_0$=2

$a_1$=25

$a_2$=16

$a_3$=18
