1. egg cooking: three eggs in a pan of water. 2. metal rusting: an abandoned, rusting car. 3. wood burning: a lit match. 4. cement hardening: men pour cement from cement mixer.

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.

the answer is c.the valence of the atoms combine .
