Question

In two or more complete sentences explain how to balance the chemical equation,

CH4 + O2 ⟶ CO2 + H2O and include all steps.

Answer 1

`\huge \boxed{\mathrm{CH_4+ 2O_2 \Rightarrow CO_2 +2 H_2O}}`

`\rule[225]{225}{2}`

Step-by-step explanation:

`\sf CH_4+ O_2 \Rightarrow CO_2 + H_2O`

Balancing the Hydrogen atoms on the right side,

`\sf CH_4+ O_2 \Rightarrow CO_2 +2 H_2O`

Balancing the Oxygen atoms on the left side,

`\sf CH_4+ 2O_2 \Rightarrow CO_2 +2 H_2O`

`\rule[225]{225}{2}`

Answer 2

There is one carbon from one side and one from the other. But we must multiply the hydrogens( water) from the products by 2. Finally the atoms of oxygen from the products are 2+1×2=4 so we must multiply by 2 the O2
