From the table of densities found in this experiment, iron has a density of 7. 85 g/cm3 and water has a density of 1. 0 g/ml. Iron is denser than water and will sink when placed in water. Explain how ships made from iron stay afloat using density principles.

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 would only be the stuff in module eight so you need to study all the lessons in that you also could check the flvs

hope this : )
