(15 points) will mark branliest if ! imagine you are trying to determine whether chemicals r and s are similar. a) separately, you react r and s with chemical x and each produced a color change from red to yellow. at this point, do you think r and s are similar? how similar? this point, do you think r and s are similar? how similar? are similar? how similar? b) now r and s are reacted separately with y. r makes a black precipitate while s has no reaction. at c) now r and s are reacted separately with z. both produce a gas. at this point, do you think r and s

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
