Which statement describes redi's experiment, which disprove spontaneous generation? he examined covered and uncovered meat to determine that maggots came from eggs. he heated milk to show that it could destroy bacteria. he wrote a book on how cells come from other cells through reproduction. he showed that the shape of a flask was important to the experiment.

i just learnt this recently but i need to look through my notes again

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.
