Chemistry I (Science Majors) (CHEM-141... Ć Malachite is a green copper mineral with the formula Cu₂CO3(OH)2. It can be converted into copper metal in a number of ways. One method extracts the metal by reacting the malachite with sulfuric acid to form CuSO4, and then adding iron to the CuSO4 solution which, after they react, forms FeSO4 and copper metal. The balanced chemical reactions are: Cu₂CO3(OH)2 (s) + 2 H₂SO4 (aq) →2 CuSO4 (aq) + 3 H₂O (1) + CO₂ (g) CuSO4 (aq) + Fe (s) →FeSO4 (aq) + Cu (s) If the final solution is dried, and 3.28 g of iron sulfate is collected, how many grams of malachite were originally used?

This module discusses the characteristics of carbohydrates, fats, and proteins. Enzymes are a special class of proteins that perform a wide variety of functions essential for the well-being of a living organism. In humans, a class of enzymes, which is of particular interest, are the liver enzymes. They break down all toxins encountered by humans. Research and describe the underlying causes for the elevated levels of any one of the liver enzymes described in a liver function test.Ask ONE (1) clarifying question about a topic you find difficult or want to learn more about from the concepts introduced in this module.In your response to your peer’s posts, locate a resource that may help address the clarifying question regarding the genetic topic in the initial post.

Chemistry of Fire Extinguishing Agents: Review and answer the below scenerios. a. The OSHA regulation at 29 C.F.R. §1910.162(b)(5) requires employers to provide a predischarge-employee alarm system to alert employees if a carbon dioxide concen-tration of 4% or greater is released from a fixed extinguishing system in a workplace. What is the most likely reason OSHA enacted this regulation?  b. At 14 C.F.R. §121.265, FAA allows carbon dioxide to be used as a fire extinguish-ing agent onboard aircraft, provided that provisions are made to prevent harmful concentrations from entering any personnel compartment. Use Table 5.6 to deter-mine whether adverse health effects are likely to be experienced by a crew member who is confined to a compartment in which the air contains 8, carbon dioxide. c. The chemical formula of methyl bromide is CH3Br. Why does methyl bromide per-form effectively as a fire extinguishing agent? d. A potential risk of inhalation toxicity may occur to individuals that…
