The fizz produced when an AlkaSeltzer® tablet is dissolved in water is due to the reaction between sodium bicarbonate, NaHCO3, and a triprotic organic acid, citric acid, H3C6H5O7. The products of this reaction are carbon dioxide gas, water, and sodium citrate. 3 NaHCO3 (aq) + H3C6H5O7 (aq)→ 3 CO2 (g) + 3 H2O(l) + Na3C6H5O7 (aq) In an experiment 1.00 g of sodium bicarbonate and 1.00 g of citric acid are allowed to react. A.Which of the five compounds in...

-The fizz produced when an alka seltzer tablet is dissolved in water is due to the reaction between sodium bicarbonate NaHCo3 and Citric acid C6H8O7. What volume, in Liters, of a 2.50-M NaHCO3 solution is needed to react completely with 0.025L of a 3.00-M C6H8O7 solution? The balanced eq is 3NaHCO3+C6H8O7=3CO2+3H2O+Na3C6

1. Moles of Reactant to Mass of Reactant: Identify the iodide ions and ozone in the balanced chemical equation. Use mole ratio, then convert to grams. A method used by the EPA for determining the ozone concentration in the air is to pass an air sample through a bubbler containing iodide ions. The iodide ions remove the ozone according to the following reaction: O3(g) + 2 I-(aq) + H2O(l) → O2(g) + I2(aq) + 2 OH-(aq) How many grams of ozone...

Questions, please
An Alka-Seltzer tablet consists of NaHCOs (sodium bicarbonate), citric acid (H3C&HsO; citric acid is triprotic), aspirin and other inert ingredients. When dissolved in water, citric acid and NaHCO3 components react as follows: In the first part of the experiment, we will determine the mass of NaHCO in a tablet of Alka Seltzer. To do this, we will use a known mass of a powdered sample of Alka-Seltzer and determine the mass of CO2 gas...

8. A student performs parts A and B of the experiment and attains an average percent yield from the Alka- Seltzer of 64.6%. Using this value and the following data perform the calculations for part B and complete the table below. Assume the pressure has not changed. As it states in the manual: You may apply the findings regarding percent-yield in Part A to Part B when calculating the moles of calcium carbonate Trial 2 Trial 1 Mass Antacid used...

Below is a lab hand out for the questions. All my data for the questions are filled out below in BOLD LETTERING. All the questions I need answered are at the bottom with boxes where to put the answers. Background Alka-Seltzer� is an over-the-counter antacid and pain relief drug. The tablet contains aspirin (acetylsalicylic acid), citric acid, and sodium bicarbonate (NaHCO3). Sodium bicarbonate (NaHCO3) is responsible for the effervescent action of Alka-Seltzer. In this lab we will investigate the reaction...

3. An ether solution of 1,1-cyclohexanedicarboxylic acid (CDA),
a compound with two carboxyl (CO2H) groups, was extracted with
10.0% NaHCO3 (aq) solution. Assume that the reaction between
1,1-cyclohexanedicarboxylic acid and NaHCO3 (aq) goes to
completion; i.e. the limiting reagent (CDA) is used up on both
carboxyl groups. Please, provide a balanced chemical equation for
the complete depronation of 1,1-cyclohexanedicarboxylic acid by
NaHCO3, in which both carboxyl groups react. Provide your answer as
chemical structures and NOT molecular formulas for ALL...
