Question

Help with enthalpy please!!!

CH4(g)+O2(g)-> H2O(g)+CO2(g)

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

It says Methane+Oxygen forms Water+Carbon dioxide and everything is in gaseous state.
CH4+2O2->2H2O+CO2
