A cork popper. To entertain children between the ages of 22 and 90, Daniel Harris enjoys popping corks from bottles containing vinegar and baking soda. He pours about 50 mL of vinegar into a 500‑mL plastic bottle. Then, he wraps about 5 g of baking soda (which is sodium bicarbonate, NaHCO3) in one layer of tissue and drops the tissue into the bottle. He places a cork tightly in the mouth of the bottle and steps back. The chemical reaction generates CO2(g) that pressurizes the bottle and eventually bursts the cork into the air.
Bay Water Titration The concentration of Cl- in ocean water is about 500-600 mM. The baywater is diluted by a factor of 12.5 using a 20.00 mL volumetric pipet and a 250 mL volumetric flask. Using a 15.00 mL volumetric pipet, 15.00 mL is transferred into three clean Erlenmeyer flasks. 10 mL of 1% dextrin solution, 20 mL of de-ionized water, and 3-4 drops of indicator are added and titrated each with the AgNO3 solution. From the procedure, find: Dilution factor Volume of diluted bay water Then calculate: The [Cl-] of diluted bay water The [Cl-] of bay water Consider this information: [AgNO3] = 0.04043177 trial # Veq 1 13.91 2 13.73 3 13.9 4 13.86 5 13.87 6 13.84 average 13.85167 [Cl-]Bay = ([AgNO3](Veq(ave))/Vdil bay water pipeted) (Vflask/Vbay water)

A 1.250 g sample of bauxite (the primary ore of aluminum) was analyzed for aluminum. The sample was powderized and treated in concentrated nitric acid. The nitric acid was removed and solids were treated in hot water with added nitric acid. Insoluble solids were removed by gravity filtration. The solution was made basic by the slow addition of dilute ammonia forming the gelatinous precipitate (Al(OH), and Al,O,.x H2O). The precipitate was heated to coagulate it then filtered over filter paper. The paper and solids were placed in a porcelain crucible and the paper was ashed while the precipitate was ignited at 600°C to convert the precipitate to pure Al,O,. The mass of Al,O, recovered was 0.2890 g. The average mass of ash after charring 10 sheets of the identical filter paper was 0.0007 g. Calculate the percent aluminum in the bauxite ore sample.
A 0.879 g sample of a CaCl2·2H2O/K2C2O4·H2O solid salt mixture is dissolved in ~100mL of deionized water. The precipitate, after having been filtered and air-dried, has a mass of 0.284 g. The limiting reactant in the salt mixture was later determined to beCaCl2 ·2H2O. a.Write the ionic equation for the reaction. b.Write the net ionic equation for the reaction. c.How many moles and grams of CaCl2 ·2H2O reacted in the reaction mixture? d.How many moles and grams of the excess reactant, K 2C2O 4H2O, reacted in the mixture? e.How many grams of the K2C2O4·H2O in the salt mixture remain unreacted (inexcess)? f.What is the percent by mass of each salt in the mixture

Five white, 500-mg uncoated ascorbic acid (AA) tablets with an average weight of 0.6152-g were pulverized in a mortar. A sample of the powdered ascorbic acid weighing 0.4700-g was placed in an iodine flask and was dissolved in 50-mL H2SO4 then 5-g of KBr was added to the resulting solution. The solution was titrated with 47.81-mL of 0.09640 N STD. KBrO3 to reach a faint yellow endpoint then 3-g KI and 5-mL Starch TS. The blue color solution is then titrated with 2.73-mL of 0.09123 N STD. Na2S2O3 to reach the disappearance of the blue iodostarch complex. MW: KBrO3 = 167.0 ; KIO3 = 214.0 ; Na2S2O3 = 158.11 ; C6H8O6 = 176.12 Compute the milligrams of pure AA per tablet from the assay. 293.3 mg 502.5 mg None of the choices 383.9 mg
