Answer

Brief Explanations:

  1. In a chemical formula, the small number after a chemical symbol or parentheses is a subscript which shows the number of atoms or atom - groups.
  2. A chemical equation uses numbers and symbols to represent a chemical reaction and the amounts of substances involved. A balanced equation is a type of chemical equation with equal numbers of each atom on both sides.
  3. A molecule is a particle made up of two or more atoms joined together.

Answer:

  1. D. subscript
  2. B. chemical equation
  3. D. molecule
