Solution

40. b

Water (H₂O) is an example of a polar molecule since it has a slight positive charge on one side (hydrogen side) and a slight negative charge on the other (oxygen side).

41. a

Blood in its normal in suspension, which is a colloid. When applying of centrifugal force externally, blood separates into its separate components just as a suspension does.

42. a

Smallest fundamental unit of a chemical compound that can take part in a chemical reaction. A molecule is an electrically neutral group of two or more atoms held together by chemical bonds.

43. c

Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions.

44. b
