Answer :
Final answer:
Vinegar and citric acid reactions with potassium carbonate produce carbon dioxide with different limiting reactants and bubbles due to CO2 production.
Explanation:
When comparing the reactions of vinegar and citric acid with potassium carbonate, they both produce carbon dioxide gas. However, in the vinegar reaction, acetic acid reacts with potassium carbonate to form carbon dioxide, while in the citric acid reaction, citric acid reacts with potassium carbonate in a similar manner.
The limiting reactant in the vinegar reaction is acetic acid, while in the citric acid reaction, the limiting reactant is citric acid. The bubbles formed in both reactions are due to the production of carbon dioxide gas.
The amount of COâ‚‚ produced can be determined by stoichiometry calculations based on the balanced chemical equations of the reactions. In the vinegar reaction, 2 moles of acetic acid produce 1 mole of COâ‚‚, and in the citric acid reaction, the stoichiometry can be used to calculate the amount of COâ‚‚ produced as well.
