When a chemical equation in balanced, it will have a set of whole number coefficients that cannot be reduced to smaller whole numbers. what is the coefficient for 02 (2 is a subscript) when the following combustion reaction of a hydrocarbon is balanced? basically, just balance the following
_c7h14+_o2 to _co2+h20 (where 7, 14, 2, 2, and 2 are subscripts)

Answer : The balanced chemical reaction will be,

Explanation :

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.

Combustion reaction : It is a chemical reaction in which a hydrocarbon reaction with the oxygen to give product as carbon dioxide and water.

The unbalanced chemical reaction is,

This reaction is an unbalanced chemical reaction because in this reaction number of carbon , hydrogen and oxygen atoms are not balanced.

In order to balance the chemical equation, the coefficient '2' put before the , the coefficient '21' put before the , the coefficient '14' put before the and the coefficient '14' put before the then we get the balanced chemical equation.

The balanced chemical reaction will be,
