Each shape in the chart represents a different type of atom. Atoms with a line (stick) between them show a chemical
bond. Cells A through D tell you whether or not a chemical bond occurs when the atoms combine.
Use the drawing tool to fill in cells A through D in the chart. Show what will happen when the atoms or molecules
combine. Use stick models as necessary.

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .
