Which of the following is the correct equation for the reaction below?
One molecule of methane gas reacts with two molecules of oxygen gas to
form one molecule of carbon dioxide gas and two molecules of water vapor.
O
A. CH (g) + O2 (g) - CO (g) + H20 (g)
O B. CH (9) + 20 (g) → CO(g) + 2H0 (9)
O C. CH4 (g) + 2O2 (g) – có (g) + 2H20 (g)
OD. CHA (9) + 202 (9) ► 02 (9) + H20 (9)

Answer:

CH₄
_((g)) + 2O₂
_((g)) → CO₂
_((g)) + 2H₂O
_((g))

Step-by-step explanation:

This kind of reaction in which a hydrocarbon combines with oxygen gas is a combustion reaction. They are mostly used to produce heat energy that can be transformed into other forms of energy.

Every chemical reaction is made up of reactants and products. The combining species on the left hand side are the reactant and the products are the result of the combination.

Note: in writing chemical equations, the state of matter must always be included.

Reactants : Methane gas CH₄

Oxygen gas O₂

Product: Carbon dioxide CO₂

Water vapor H₂O

CH₄
_((g)) + 2O₂
_((g)) → CO₂
_((g)) + 2H₂O
_((g))
