Question

Examine the equation.

CH4 + 2O2 → CO2 + __H2O

In order to balance the equation, what coefficient must be placed in front of H2O?

2
4
1
3

Answer 1

`\huge \boxed{\mathrm{2}}`

`\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

the answer is 2
