A 0.70 g mixture of Cu and CuO was treated with hydrogen at elevated temperature. CuO was
reduced to Cu and water was formed.
(a) Write a balanced equation for the reaction. (2 marks)
(b) Before the experiment, calculate the minimum amount (in mole) of hydrogen required
to ensure the reduction is completed. (3 marks)
(c) After passing with in excess amount of hydrogen gas, 0.58 g of solid remained.
Calculate the percentage of CuO in the mixture.
