Marking points
B1 (a) · 1 mark · Correctly identifies magnesium as a metal.
B1 (b) · 1 mark · States that magnesium oxide reacts with acids (not alkalis or both).
B1 (c) · 1 mark · Correctly states that non-metal oxides are acidic.
Worked solution
a) Magnesium oxide is formed from magnesium, which is a metal. So the correct answer is 'metal'.
b) Magnesium oxide reacts with acids (because it is basic) but not with alkalis.
c) Non-metal oxides are generally acidic.
