Calculate ΔH for the reaction C2H4 (g) + H2 (g) → C2H6 (g), from the following data:
C2H4 (g) + 3 O2 (g) → 2 CO2 (g) + 2 H2O (l) ΔH = -1411. kJ
C2H6 (g) + 7/2 O2 (g) → 2 CO2 (g) + 3 H2O (l) ΔH = -1560. kJ
H2 (g) + 1/2 O2 (g) → H2O (l) ΔH = -285.8 kJ

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
