Answer:
Sodium
Hydrogen
Carbon
Oxygen
Explanation:
Formula of baking soda is NaHCO₃. It is the salt consist of sodium (Na⁺) cation and bicarbonate (HCO₃⁻) anion. It is also called sodium hydrogen carbonate. It is crystalline white solid.
Elements in baking soda:
Sodium:
Sodium is present in third period and group one of periodic table. It is eleventh element of periodic table. It is alkali metal and lose one valance electron thus carry +1 charge.
Hydrogen:
It is first element of periodic table. Its atomic number is one and mass is 1.008 g/mol. It can lose its one electron and has +1 charge.
Carbon:
It is present in the group fourteen of periodic table. It can lose its four valance electrons and form four covalent bonds. Its atomic number is six and atomic weight is twelve.
Oxygen:
It is the eighth element of periodic table. It is present in group sixteen and second period of periodic table. It has six valance electrons. It is also called chalcogen because it is ore forming element.

%
Explanation:
If we know the grams of a chemical compound in a specific reaction, it is possible to know the percentage of each atom that composes it.
For the Aluminum Oxide in this problem, we know its total weight and the grams of each component.
therefore we can determine the percentage ratio of its components through:
