The diagram shows the different models of the atom that eventually led to the modern atomic theory. four diagrams are shown labeled model a, model b, model c, model d from left to right. the diagram labeled model a has a small sphere with a positive sign on it. this small sphere at the center is surrounded by a shaded circle. the shaded circle has negative signs placed randomly inside it. the diagram labeled model b is a large solid sphere. the diagram labeled model c has a sphere at the center and a dotted cloud around the sphere. the dotted cloud is dense near the sphere and becomes faint as we move away from the sphere. the diagram labeled model d has a sphere surrounded by three concentric circles. each concentric circle has some spheres on it. which model is based on bohr's quantum model? model a model b model c model d

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 .
