            When heated, magnesium reacts with oxygen in the air to form magnesium oxide, a white powder.

            A student investigates the change in mass that occurs during this reaction. The student is given a balance and the three sets of apparatus shown.

            Three sets of apparatus labelled 1, 2 and 3. Apparatus 1 shows burning magnesium held in the open air by metal tongs. Apparatus 2 shows magnesium inside a horizontal tube with air flowing in from the left and heat applied from below. Apparatus 3 shows magnesium in a crucible with a lid, standing on a tripod with heat applied from below, and metal tongs for lifting the lid

            Which sets of apparatus are suitable for this investigation?

            • 1, 2 and 3

            • 1 and 3 only

            A student prepared crystals of potassium chloride by the following method.

            1. 25.0 cm3 of dilute hydrochloric acid was accurately measured into a conical flask using a measuring cylinder.

            2. Aqueous potassium hydroxide was added from a burette until the solution was neutral.

            3. The solution was evaporated and the crystals washed with approximately 20 cm3 of water measured using a pipette.
