Explain how electrons are arranged.

Electrons occupy energy levels/shells. Electrons occupy the lowest level (first one from the nucleus) first which can occupy a maximum of 2 electrons. After the first level, electrons fill up the other shells with a maximum of 8 electrons.

In terms of structure and bonding, explain why graphite is able to conduct electricity.

5.00 g of copper(II) carbonate decomposes to form copper(II) oxide and carbon dioxide: CuCO3(g) → CuO(s) + CO2(g). Calculate the maximum mass of carbon dioxide that can be produced. (Mr of CuCO3 = 123.5, Mr of CO2 = 44.0)

How do endothermic and exothermic reactions differ?

Calculate the concentration in mol/dm3 of 8.0 g of sodium hydroxide (NaOH) in solution with a volume of 50 cm3. (Note Ar(Na) = 23, Ar(O) = 16, Ar(H) = 1)
