Copper(II) oxide reacts with dilute sulphuric acid according to the following equation.
CuO + H2SO4 = CuSO4 + H2O
A student uses this reaction to prepare crystals of copper(II) sulphate.
(a) To make sure that the crystals are pure, an excess of copper(II) oxide must be used
(i) Explain why an excess of copper(II) oxide must be used to ensure purity of the
crystals.

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
