The following balanced equation shows the formation of water. 2h2 + o2 > 2h2o how many moles of oxygen (o2) are required to completely react with 27.4 mol of h2? a: 6.8 mol b: 13.7 mol c: 54.8 mol d: 109.6 mol

Im not entirely sure, but i think the answer is c was i right let me know.

what is the question here. i think you messed up.

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.
