Scenario for Questions 3. - 5.
Scenario for Questions 3. - 5. In an experiment, 0.500 grams of sodium bicarbonate were added to an evaporating dish and an excess of 6.0 M hydrochloric acid was added. The bicarbonate bubbled with the addition of the aqueous HCl. The evaporating dish was gently swirled until the bubbling stopped. The evaporating dish was placed on a hot plate and heated carefully to dryness so that it was completely dry and at constant mass. The amount of sodium chloride obtained from the evaporating dish was 0.114 g.
The reaction is given below.
NaHCO3 (s) + HCl (aq) ---> NaCl (s) + CO2 (g) + H2O (l)
(1 point) Is the reaction balanced?
(1 point) What was in the bubbles?
(3 points) What were the actual, theoretical, and percent yields of sodium chloride (NaCl)? You must show your work to receive credit.
