A solution is prepared by dissolving 11.6 g of a mixture of sodium carbonate and sodium bicarbonate in 1.00 L of water. A 300.0 cm3sample of the solution is then treated with excess HNO3 and boiled to remove all the dissolved gas. A total of 0.940 L of dry CO2 is collected at 298 K and 0.972 atm. 1. Find the molarity of the carbonate in the solution. 2. Find the molarity of the bicarbonate in the solution.

3.0012g of an unknown mixture of sodium carbonate (Na2CO3) and sodium bicarbonate (HNaCO3) is mixed with nitric acid (HNO3). 0.487277837 liters of CO2 is produced. What is the mass in grams and percent of carbonate (CO3-) in the original sample (295.25K, 0.97012 atm). 486.18g of H2O was produced. Density of water at that temperature is 0.997747g/mL.

Suppose you add a solution of calcium hydroxide to a solution of sodium carbonate and a precipitate forms. You measure the total amount of the precipitate (in g) as a function of time. At time 0, 20.0 s, 40.0 s and 60.0 s you get a cumulative weight of 0.00 g, 4.82 g, 6.33 g and 8.49 g of the precipitate, respectively. What is the average rate of reaction between 40 and 60 seconds in mol/s? Enter a numerical value...

Some commercial drain cleaners contain a mixture of sodium hydroxide and aluminum powder. When the mixture is poured down a clogged drain, the following reaction occurs: 2NaOH(aq) + 2Al(s) + 6H2O(l) → 2NaAl(OH)4(aq) + 3H2(g) The heat generated in this reaction helps melt away obstructions such as grease, and the hydrogen gas released stirs up the solids clogging the drain. Calculate the volume of H2 formed at 23°C and 1.00 atm if 3.12 g of Al are treated with an...

A 3.900 g sample of a mixture of sodium hydrogen carbonate and potassium chloride is dissolved in 25.80 mL of 0.439 M H2SO4. Some acid remains after treatment of the sample. Write both the net ionic and the molecular equations for the complete reaction of sodium hydrogen carbonate with sulfuric acid. If 34.8 mL of 0.109 M NaOH were required to titrate the excess sulfuric acid, how many moles of sodium hydrogen carbonate were present in the original sample? What...

what procedure allows us to isolate and extract plasmid DNA and to avoid isolating the larger circular genomic-chromosomal DNA? Why do many restriction enzymes require a 37 C temperature to be active and to hydrolyze DNA molecules while other restriction enzymes require 50 C temperature to be active and to hydrolyze DNA molecules?
