Question

What coefficient is placed in front of O2 to complete the balancing of the following equation C5H8+?O2→5CO2+4H2O?

Answer 1

at right side here is 14 O atoms so according to mass conservation the co efficient of O2 is 7

Answer 2

A coefficient of 7 is placed in front of $O_2$ to complete the balancing of the equation $C_5H_8+7O_2\rightarrow 5CO_2+4H_2O$

Explanation:

Law of conservation of matter : It states that matter can neither be created nor be destroyed but it can only be transformed from one form to another form. The balanced chemical reaction always follow the law of conservation of mass.

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

The balanced chemical reaction is:

$C_5H_8+7O_2\rightarrow 5CO_2+4H_2O$
