Answer

Brief Explanations:

  1. A molecule is composed of atoms joined by covalent bonds, not just ionic bonds. So the first statement is false.
  2. Blue litmus paper turns red in acidic solutions, and HCl(aq) is an acid. So the second statement is true.
  3. Acids are characterized by a sour taste, not a bitter taste. So the third statement is false.
  4. Bases have a pH greater than 7, not less than 7. So the fourth statement is false.
  5. A binary ionic compound is composed of a metal cation and a non - metal anion, not two metal cations. So the fifth statement is false.

Answer:

  1. B. False
  2. A. True
  3. B. False
  4. B. False
  5. B. False
