One day, after much exercise, my friends and I were thirsty. Upon searching through the refrigerator, we found a variety of liquids to drink: water, orange juice with extra pulp, milk with extra calcium added and iced tea. Use the following terms to label each of the italicized items listed above: element, compound, solution, colloid and suspension.

Water = compound, Orange juice with extra pulp = suspension, Milk = colloid, Calcium = Element, Iced tea = solution.

Explanation:

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.
