Question

200 ml of CH4 at N.T.P. requires for complete combustion :
(1)400 ml of oxygen at N.T.P.
(2) 200 ml of oxygen at N.T.P.
(3) 100 ml of oxygen at N.T.P.
(4) 800 ml of oxygen at N.T.P.
​

Answer 1

Answer:

ch4+2O2=CO2+2H2O =1

Explanation:

1 mole of CH4=2 mole of oxygen

so for 200ml gives 400ml

Answer 2

400ml

Explanation:

CH4+2O2=CO2+2H20

22400ML CH4=2×22400ML O2

200ML CH4=400ML 02
