Question

A combustion reaction occurs between one molecule of methane (CHa) and two molecules of oxygen (O2).

Answer 1

The total number of atoms make up the products :

D) 1 carbon, 4 hydrogen, and 4 oxygen

Further explanation

Complete combustion of Hydrocarbons with Oxygen will produce CO₂ and H₂O compounds.

If O₂ is insufficient there will be incomplete combustion produced by CO and H and O

Hydrocarbon combustion reactions (especially alkanes)

For combustion of methane (CH₄) and two molecules of oxygen (O₂).

$\tt CH_4+2O_2\rightarrow CO_2+2H_2O$

The number of atoms make up the products

CO₂ : 1 carbon, 2 oxygen

2H₂O : 4 hydrogen , 2 oxygen
