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.

Answer:
The answer is A.) age
Explanation:
The older the sample, the more the sample will have decayed, and the less radioactive it will be.
Answer:
This question appears incomplete
Explanation:
However, an alpha hydrogen is the hydrogen that is found on the alpha, α-carbon in an organic molecule. Alpha carbon is referred to the first carbon that is attached to a functional group. Generally, compounds that do not have alpha carbon do not have alpha hydrogen. For example, first member of all functional groups do not usually have alpha carbon and hence do not have alpha hydrogen.
Also, Alkanes, alkenes and alkynes do not have also
