Every sheet in July 1996
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st July 1996Name the salt made from zinc oxide and nitric acid.
- 2nd July 1996State what is meant by a catalyst.
- 3rd July 1996State what happens to the carbon-to-carbon double bond of an alkene monomer during addition polymerisation.
- 4th July 1996Describe, in terms of wavelength, the difference between the radiation the Earth receives from the Sun and the radiation it re-emits from its surface.
- 5th July 1996Define specific heat capacity.
- 6th July 1996State what happens to the internal energy of a substance as it is heated, in terms of the kinetic and potential energy of its particles.
- 7th July 1996State the number of protons and the number of neutrons in an alpha particle.
- 8th July 1996Name the type of electromagnetic wave used to sterilise medical equipment.

- 19th July 1996Name the two industrial methods of cracking.
- 20th July 1996State one advantage of running known reference substances alongside an unknown sample on the same chromatogram, rather than only comparing to published Rf values.
