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.

Concept explainers

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".

Predict the reactants of this chemical reaction. That is, fill in the left side of the chemical equation. Be sure the equation you submit is balanced. (You can edit both sides of the equation to balance it, if you need to.) Note: you are writing the molecular, and not the net ionic equation. [] → Ba(C1O₂)₂(aq) + H₂O(1) 2 X G

There are two steps in the extraction of copper metal from chalcocite, a copper ore. In the first step, copper(I) sulfide and oxygen react to form copper(I) oxide and sulfur dioxide: 2 Cu₂ S(s) + 3 0₂(g) →2 Cu₂O(s) +2 SO₂ (g) In the second step, copper(I)oxide and carbon react to form copper and carbon monoxide: Cu₂O(s) + C(s)→2 Cu(s)+CO(g) Write the net chemical equation for the production of copper from copper(I) sulfide, oxygen and carbon. Be sure your equation is balanced. ローロ 06
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.
