e)Why does hard water form insoluble scum with soap?


Pls answer c) d) and e)

Answer 1

Answer:

a] Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules.

b] u nsaturated Hydrocarbons are also known as Alkenes or Alkyenes. Saturated molecules have only sigma bonds, which are very stable and hard to break. Unsaturated molecules, however, have pi bonds, and they are weaker. They deform the orbitals slightly and are more strained
