Combustion of one methane gas molecule gives ________ carbon dioxide and __________ water molecules. respectively.

Correct option is B

Methane gas:

·        ​Methane, which has the chemical formula CH4, is the simplest of the saturatedhydrocarbons. The simplest alkane is composed of one carbon atom and four hydrogen atoms.

·        Atmospheric methane, which can be found both below the seafloor and above ground, is produced when natural methane reaches the surface of the atmosphere.

·        It has no color, has no smell, or smells like sweet oil. It is a gas that is not harmful but can burn. It is a molecule with four equivalent C-H bonds and a tetrahedral shape.

·        Anaerobes in the colon make it. In 1776, Italian physicist Alessandro Volta was the first to scientifically identify methane.

Combustion of methane gas ​

·        The term "combustible" refers to the possibility of burning methane. Methane and oxygen undergo a chemical reaction in this process.

·        A lot of energy, water (H2O), and carbon dioxide (CO2) are the byproducts of this reaction.

·        To represent the combustion of methane, chemists would write: CH₄[g] + 2 O₂[g] -> CO_2[g] + 2 H₂O[l] + 891 kJ
