A20 gram piece of metal is added to a sample of 100 grams of water inside a calorimeter. if the metal is at a temperature of -5° celsius and the water is at 20° celsius, which of the following best describes what will occur inside the calorimeter? the final temperature of the water will be 15° celsius. the energy gained by the metal equals the energy lost by the water. the final temperature of the water will be higher than the initial temperature. the temperature lost by the water will equal the temperature gained by the metal

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 .
