Suppose you work for a government office that needs to find a suitable place to bury barrels of poisonous liquid wastes. the soils that are used to bury the waste should have properties that will prevent the liquid from moving quickly down toward the groundwater–just in case the barrels begin to leak at some point. you should look for a soil with which type of texture? sandy silty clay rich loam

Which scenario is most similar to the type of collision that gas particles have according to kinetic molecular theory

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 .

Which is an example of a reversible physical change?
