The answer is: emitted gas is carbon dioxide (CO₂).
Neutralization is is reaction in which an acid (in this example vinegar or acetic acid CH₃COOH) and a base (in this example soda)
Balanced chemical reaction of vinegar and antacid:
CH₃COOH(aq) + NaHCO₃(aq) → CH₃COONa(aq) + H₂O(l) + CO₂(g).
Sodium acetate (CH₃COONa) is a salt.
Sodium bicarbonate (NaHCO₃) is an antacid. Sodium bicarbonate is the active ingredient in baking soda.
The correct answer would be A.

The molar mass of nitrogen is 14 bt since it is a nitrogen molecule (N2) the molar mass will be 14 x 2 = 28g/mol.
Step 1: Calculate the moles of N2
moles = mass / relative molecular mass
= 50g / 28g/mol
= 1.7857mol
Step 2: convert the moles of nitrogen into volume of N2
At STP the molar volume of a gas is 22.71L/mol
Hence the volume = 1.7857mol x 22.71L/mol
= 40.55L
50g if nitrogen (N2) has a volume of 40.55 liters at stp.
