Question 1 1.0g BaCl2 was dissolved in water, and sodium sulphate solution added until no more precipitate was formed. Assuming BaSO4 (s) is totally insoluble, what mass of barium sulphate would form?

Question 2 Water can be separated into hydrogen and oxygen gases by using electricity to break the bonds in a process called electrolysis. The reaction is: 2H2O → 2 H2(g) + O2(g) How many moles of H2 gas would be formed from the electrolysis of 10 moles of water?

Question 3 Copper sulfate and zinc metal react to form zinc sulfate and copper by the reaction: CuSO4 + Zn → ZnSO4 + Cu How many grams of copper are produced from 2.9 grams of zinc consumed with excess CuSO4in this reaction?

** Please note that in the pencast, the audio for Question 2 is repeated...
