Michael is testing out the following reaction: Na2CO3+ 2HCl à 2NaCl + H2O + CO2. He combines sodium carbonate with hydrochloric acid in a 100 mL graduated cylinder and covers the mouth of the graduated cylinder with a balloon. Michael fills out the data table. Substance/Material Measurement Mass of sodium carbonate 2.5 g Mass of empty graduated cylinder 72.5 g Mass of graduated cylinder with HCl 88.8 g Mass of empty balloon 0.4 g Mass of final experiment XXX g In order to show evidence supporting the Law of Conservation of Mass, what should Michael find as the final mass, and why? A 18.8 g, because only the mass of the products should be accounted for, not the equipment. B 19.2 g, because the mass of the products and the balloon should be accounted for. C 75.4 g, because this mass accounts for all equipment and products in the reaction. D 91.7 g, because this mass accounts for all equipment, reactants, and products created in the reaction.

An environmental chemist working for the Environmental Protection Agency (EPA) was directed to collect razor clams from a heavily-contaminated river superfund site and analyze them for their Cd?+ content using graphite furnace atomic absorption spectrometry (GFAAS). The chemist dried the clams at 95 °C overnight and ground them in a scientific blender, resulting in approximately 50 g of homogenized dry weight. A representative 98.75 mg sample was taken from the approximately 50 g of dry material and dissolved in 100.0 mL of 0.1 M HCI to create a sample solution. Using the method of standard additions, the chemist prepared five standard solutions in 100.0 mL volumetric flasks, each containing 5.00 mL aliquots of the sample solution. Varying amounts of a 75.0 ppb (ug/L) Cd? + standard were added to each of the flasks, which were then brought to volume with 0.1 M HCI. The Cd? + content of the solutions was then analyzed using GFAAS, resulting in the. absorbance data given in the table.…

Pesticide residues were found in a lot of oranges; the compound identified was the epoxide of heptachlor (EH). To quantify the amount of this pesticide in oranges, 20 grams were taken from fruit peels and mixed with methylene chloride to extract it. The concentration of heptachlor epoxide in the sample was determined by gas chromatography coupled to a detector mass (GC-MS); and calibration was performed using anthracene (A) as internal standard. For In this analysis, the anthracene had a concentration of 350 ppm and the same volume was added to each standard. The table below shows the concentrations of the standard and the ratio of the areas.and the sample is: 0.1080.Determine the concentration of heptachlor epoxide in the sample.
