What is the mass percent of each acid in the mixture? (Acetic acid does not react with MnO4−. The equation for the reaction of oxalic acid with MnO4− is given below: 5H2C2O4(aq)+2MnO4−(aq)+6H+(aq)⟶10CO 2(g)+2Mn2+(aq)+8H2O(l)

elements make up everything, and they combine to make compounds.

the answer is c

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.
