Elixirs such as Alka-Seltzer use the reaction of sodium bicarbonate with citric acid in aqueous solution to produce a fizz: What mass of should be used for every 4.2 x mg ? Mass of = g What mass of could be produced from such a mixture? Mass of = g
Added by Daniel C.
Step 1
Reaction: C6H8O7 + 3 NaHCO3 -> Na3C6H5O7 + 3 CO2 + 3 H2O. Molar masses used: NaHCO3 = 84.01 g mol^-1, citric acid (C6H8O7) = 192.12 g mol^-1, CO2 = 44.01 g mol^-1. Interpret the given 4.2 x mg as 4.2 x 10^2 mg = 420 mg = 0.420 g of NaHCO3. Show more…

Elixirs such as Alka-Seltzer use the reaction of sodium bicarbonate with citric acid in aqueous solution to produce a fizz: 3NaHCO3(aq) + C6H8O7(aq) → 3CO2(g) + 3H2O(l) + Na3C6H5O7(aq) a. What mass of C6H8O7 should be used for every 2.0 10^2 mg NaHCO3? Mass of C6H8O7 = g b. What mass of CO2(g) could be produced from such a mixture? Mass of CO2(g) = g

Elixirs such as Alka-Seltzer use the reaction of sodium bicarbonate with citric acid in aqueous solution to produce a fizz: 3NaHCO3(aq) + C6H8O7(aq) → 3CO2(g) + 3H2O(l) a. What mass of C6H8O7 should be used for every 5.5 x 10^2 mg NaHCO3? Mass of C6H8O7 = g b. What mass of CO2(g) could be produced from such a mixture? Mass of CO2(g) = g

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 1.25 g of sodium bicarbonate and 1.25 g of citric acid are allowed to react. How many grams of carbon dioxide form? How many grams of the excess reactant remain after the limiting reactant is completely consumed?
