Answer :

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

Answer:

c) There are three atoms of oxygen in sodium bicarbonate

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).
