What can be concluded from the following statements about a property of metals? A cast-iron skillet on a stove used to fry bacon.
A metal spoon left in a pot of soup heating on a stove is too hot to touch.
An aluminum playground slide gets hot on a summer day.

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.

it's c (engineer's do their work with mechanical stuff not on any living being)

c. 4.54 x 10–12 j happens to be correct
