In the combustion of 2.0 gm of methane 25 kcal heat is liberated, heat – InterviewSolution

1.	In the combustion of 2.0 gm of methane 25 kcal heat is liberated, heat of combustion of methane would be
Answer» 100 kcal 200 kcal 300 kcal 400 kcal Solution :`CH_(4)+2O_(2)rarrCO_(2)+2H_(2)O` Molecular weight of `CH_(4)=12+4=16` `therefore` On the COMBUSTION of 2.0 gm of methane = 25.0 kcal `therefore` On the combustion of 16.0 gm = `(25xx16)/(2)` = 200 kcal.
