Question

the image shows the reaction of methane. which equation represents this chemical reaction?
a. ch₄ + o₂ = co₂ + h₂o
b. 2ch₄ + 4o₂ = 2co₂ + 4h₂o
c. ch₄ + 2o₂ = co₂ + h₂o
d. ch₄ + o₂ = 2co₂ + 2h₂o
e. ch₄ + 2o₂ = co₂ + 2h₂o

Explanation:

Step1: Identify reactants and products

The reactants are methane ($CH_4$) and oxygen ($O_2$), and the products are carbon - dioxide ($CO_2$) and water ($H_2O$).

Step2: Balance the chemical equation

The balanced equation for the combustion of methane is $CH_4 + 2O_2=CO_2 + 2H_2O$.

Answer:

E. $CH_4+2O_2 = CO_2 + 2H_2O$
