Calculate the maximum amount of moles of AlCl3 that can be produced when 6.82 moles of Al2O3 react with 34.1 moles of HCl according to the following equation: Al2O3(s) + 6HCl(aq) → 2AlCl3(aq) + 3H2O(aq)

i would say b

explanation:

but i think i would need more information than that

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.
