The reactants of two chemical equations are listed. Equation 1: CuSO4 and NaOH Equation 2: Fe and CuSO4 Based on the type of reaction, which reaction can be used to extract copper metal from copper sulfate solution? Equation 2, because Fe being more reactive, replaces Cu from CuSO4
Equation 2, because Fe being more reactive, replaces S from CuSO4
Equation 1, because Na being more reactive, exchanges position with Cu in CuSO4
Equation 1, because Na being more reactive, exchanges position with S in CuSO4

Which of the following best explains why the end of a spoon sticking out of a cup of hot water also gets hot? question 7 options: the heat from the hot water is conducted through the spoon handle the hot water heats the air surrounding the upper part of the spoon. the hot water causes a physical change in the spoon handle. the hot water causes a chemical reaction to take place in the spoon.

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
