MCQ
When methane burns in air, what are the products formed?
  • A
    $\text{CO}_2+2\text{H}_2\text{O}+\text{heat}$
  • B
    $\text{CO}_2+\text{H}_2$
  • $\text{CO}+\text{O}_2$
  • D
    $\text{CO}_2+\text{O}_2+\text{heat}$

Answer

Correct option: C.
$\text{CO}+\text{O}_2$
Fuels and hydrocarbons burn in oxygen and form $CO_2+2O_2→CO_2+2H_2O+$heat and give out heat. $CH_4+2O_2→CO_2+2H_2O+$heat
