Question

Sodium bicarbonate is the chemical name for baking powder. Its chemical formula is NaHCO3. What does the subscript 3 mean? a) There are three molecules of sodium bicarbonate. b) There are three molecules of oxygen in sodium bicarbonate. c) There are three atoms of oxygen in sodium bicarbonate. d) There are three atoms of sodium bicarbonate.

Answer 1

C.There are three atoms of oxygen in sodium bicarbonate.

Answer 2

c) There are three atoms of oxygen in sodium bicarbonate

Step-by-step explanation:

Because the subscripts in any chemical formula indicate the number of atoms present in such formula, if it has no subscript, it means that the number of atoms is one, so, this formula has one atom of sodium (Na), one atom of hydrogen (H), one atom of carbon (C), and three atoms of oxygen (O).
