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

Step-by-step 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
