Question

How do you balance the chemical equation CH4+ O2= CO2+ 4H2O

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

`CH4+O2=CO2+4H20`

now split the equation in half

CH4+O2 I CO2 + 4H2O

C = 1 I C = 1

H = 4 I H = 8

O = 2 I O = 3

CH4+ 2O2 = CO2 + 2H20
