A chemist waft given four unidentified. water-insoluble cubes measuring 1 times 1 times 1 cm and asked to arrange these substances in order of their increasing density. These cubes were labeled A, B, C, D. As a reference, the chemist was also given the following liquids, whose densities in gmL^-1 at 20 degree C are given below water 0.9982 nitromethane 1.13711 toluene 0.8669 chloroform 1.4832 The chemist added one of the four substances to one of the liquids and observed whether the substance floated or sank. By repeating this procedure with the other substances and liquids, he was able to make a series of observations about the relative densities of the substances and the liquids. Use the following selected observations to arrange the four unknown substances in order of increasing density. Briefly defend your order Substance A sank in chloroform Substance B floated in water but sank in toluene Substance C sank in water but floated in chloroform and nitromethane Substance D sank in nitromethane but did not sink as rapidly as Substance A did in nitromethane

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant
