Anhydrous copper (II) sulfate is a gray-white powder. When a student heated 250 gram of bright blue copper (II) sulfate pentahydrate (CuSO,.5H,0) in a crucible, the sample crumbled and turned gray white. The sample that remained after heating was 160 g only. Basec on this information, what is the most acceptable conclusion? O A The sample became dehydrated when it was heated. OB The sample went from the solid phase to the gaseous phase. OC The mass of the sample decreased after the copper (II) sulfate evaporated. OD The color of the sample changed when copper reacted with sulfate ions.

2+ Natural waters often contain relatively high levels of calcium ion, Ca²+, and hydrogen carbonate ion (bicarbonate), HCO3¯, from the leaching of minerals into the water. When such water is used commercially or in the home, heating of the water leads to the formation of solid calcium carbonate, CaCO3, which forms a deposit ("scale") on the interior of boilers, pipes, and other plumbing fixtures. Ca(HCO3)2 (aq) → CaCO3 (s) + CO2(g) + H₂O(1) If a sample of well water contains 0.0016 mg of Ca(HCO3)2 per milliliter, what mass of CaCO3 scale would 1.0 mL of this water be capable of depositing? Mass= g
Arsine, AsH3, was once a product of a test used in forensic analysis. Tissues from a possible poisoning victim were treated with zinc and sulfuric acid. If arsenic was present (usually as diarsenic trioxide, As203), arsine would form: As₂03 (s) + 6 Zn(s) + 6 H₂SO4(aq) ----> 2 AsH3(g) + 6 ZnSO4(aq) + 3 H₂O(1) a) In a lab exercise, a forensic technician reacts 19.8 g of AS₂O3 with 32.7 g of Zinc in the presence of excess sulfuric acid. What mass of AsH3 will be produced? b) Use the same chemical reaction, create a question which needs to be solved by percentage yield.

4) Zinc oxide can be produced by the following reaction: 2 Zn (s) + O2(g) 2 ZnO (s) - There are many uses for ZnO, but one is a heat- reflective coating on windows (thus lowering cooling demands in hot climates). This coating requires a thin layer (approximately 40-50 µm thick) of zinc oxide. Assume that this thin film uses 1.9x1020 Zn atoms per cm² of surface. How many grams of ZnO are added to a window that has an area of 5500 cm²? g Zno

Cobalt(II) chloride forms several hydrates with the general formula CoCl2 ·x H2O , where x is an integer. If the hydrate is heated, the water can be driven off, leaving pure CoCl2 behind. Suppose a sample of a certain hydrate is heated until all the water is removed, and it's found that the mass of the sample decreases by 22.% . Which hydrate is it? That is, what is x ?
A student performed a similar experiment to the one you performed: They took a crucible and lid, cleaned them, heated them over a flame, and after cooling found their combined mass to be 22.538 g. The student then added a sample of zinc(II) sulfate hydrate (ZnSO4·“n”H2O) to the crucible so the combined mass of the sample, crucible, and lid was 25.896 g. They heated this sample for 10 minutes with the lid ajar, let it cool, and measured the mass of the crucible, sample, and lid to be 25.054 g. a. Based on this experiment, what is the formula for they hydrated zinc(II) sulfate compound? b. The student later looked on the reagent bottle for zinc(II) sulfate hydrate and found the actual formula was ZnSO4·7H2O. If everything had been done correctly, what value should the student have expected for the final mass of their sample, crucible, and lid after heating?
