The fizz produced when an alka-seltzer tablet is dissolved in water is due to the reaction between sodium bicarbonate (nahco₃) and citric acid (h₃c₆h₅o₇):
3nahco₃(aq) + h₃c₆h₅o₇(aq) > 3co₂(g) + 3h₂o(l) + na₃c₆h₅o₇(aq)
in a certain experiment 1.00g of sodium bicarbonate and 1.00g of citric acid are allowed to react.
how many grams of carbon dioxide form?

0.47g of

Explanation:

1. Balanced equation:

3NaHCO₃(aq) + H₃C₆H₅O₇(aq) --------> 3CO₂(g) + 3H₂O(l) + Na₃C₆H₅O₇(aq)

2. Find the limiting reagent between the reactants:

-For the :

Divide the number of moles between the stoichiometric coefficient of the :

-For the :

Divide the number of moles between the stoichiometric coefficient of the :

The smallest number is the 0.004 therefore, the limiting reagent is the sodium bicarbonate.

3. Calculate the grams of carbon dioxide:

the ratio of the conjugate base to the acid required to attain the desired ph.

elements make up everything, and they combine to make compounds.

the answer is c
