Question

Identify the missing coefficient in the balanced equation and classify the type of reaction. _____C3H8 + 5O2 ⟶ 3CO2 + 4H2O

Answer 1

Combustion reaction

Answer 2

Answer : The missing coefficient in the balanced equation is, 1 and this is a type of combustion reaction.

Explanation :

Law of conservation of matter : It states that the number of atoms of each element present of the reactant side must be equal to the product side.

The given chemical reaction is,

$1C_3H_8+5O_2\rightarrow 3CO_2+4H_2O$

The given chemical reaction is balanced.

By the stoichiometry we can say that, 1 moles of propane react with 5 moles of oxygen to give 3 moles of carbon dioxide and 4 moles of water.

The given reaction is a combustion reaction.

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

Hence, the missing coefficient in the balanced equation is, 1 and this is a type of combustion reaction.
