Question

sodium bicarbonate is the chemical name for baking powder. its chemical formula is nahco3. what does the subscript 3 mean? there are three molecules of sodium bicarbonate. there are three molecules of oxygen in sodium bicarbonate. there are three atoms of oxygen in sodium bicarbonate. there are three atoms of sodium bicarbonate.

Answer 1

Answer: There are three atoms of oxygen in sodium bicarbonate.

Explanation: Chemical formula of baking powder is
`NaHCO_3`

Molecules are of of two types a) molecules of atoms and b) molecules of compounds.

Sodium bicarbonate is a molecule of compound made up of 1 atom of sodium (Na), 1 atom of Hydrogen(H), 1 atom of carbon(C) and 3 atoms of Oxygen(O).

Oxygen forms a molecule by combination of 2 atoms of oxygen i.e.
`O_2`.

Three molecules of
`NaHCO_3` will be represented as 3
`NaHCO_3`.

Answer 2

Correct answer choice is :

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

Step-by-step explanation:

Sodium bicarbonate, usually identified as baking soda, is a chemical mixture with the formula NaHCO₃. It is a salt made of sodium ions and bicarbonate ions. Sodium bicarbonate is a white solid that is crystalline but usually arrives as a fine powder. Sodium bicarbonate is an antacid utilized to reduce disease and acid pain. Your doctor also may prescribe sodium bicarbonate to make your blood or urine light acidic in several circumstances. This medicine is seldom prescribed for other uses, ask your doctor or pharmacologist for more data.
