 Nilesh Chauhan said: (May 29, 2014) 1CH4+2O2 = 1CO2+2H2O.

 Venkat said: (Aug 10, 2016) Can any one solve this problem.

 Nitin Kumar said: (Dec 11, 2016) 1CH4 + 2O2 = CO2 + 2H2O. 1[12 + 4] + 2[32] = [12 + 32] + 2[2 + 16}, 16 + 64 = 44 + 36, 80 = 80. So the question is correct.

 Anand said: (May 22, 2017) Well said @Nitin.

 Waseem said: (Jul 1, 2017) According to Avagdro law, equal volume of different gases at same temperature and pressure contain a same number of molecules. And the number of molecules is related to the number of moles. So we can say a number of moles are same as volume.

 Sumit said: (Jul 9, 2017) @Nitin. It will need one more molecule of oxygen to be balanced.
