Water has a boiling point of 100°c and a heating capacity of 4186 joules (1 cal/g×°c) while ethanol has a boiling point of 78.37°c along with heating capacity of 2.64 joules (0.59 cal/g× °c). How does the difference between the heat capacity of these substances directly impacts the difference seen in their boiling point?

Can someone me with these questions plz.

There are main groups in the modern periodic table of elements

Consider the reduction reactions and their equilibrium constants. cu+(aq)+e−↽−−⇀cu(s)pb2+(aq)+2e−↽−−⇀pb(s)fe3+(aq)+3e−↽−−⇀fe(=6.2×108=4.0×10−5=9.3×10−3 cu + ( aq ) + e − ↽ − − ⇀ cu ( s ) k =6.2× 10 8 pb 2 + ( aq ) +2 e − ↽ − − ⇀ pb ( s ) k =4.0× 10 − 5 fe 3 + ( aq ) +3 e − ↽ − − ⇀ fe ( s ) k =9.3× 10 − 3 arrange these ions from strongest to weakest oxidizing agent.
