Reorganize the following conversion factors so that they are in the correct order to solve the following problem. Calculate the number of grams of CO2 produced when 50.6 g of CH4, reacts with excess O2
CH4 + 2O -> CO2+ 2H2O
44.01 g CO2
1 mole CO2
1 mole CH4
16.01 g CH4
1 mole of CO2
1 mole CH4

the answer is option a.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
