Every sheet in November 1997
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st November 1997Define phenotype.
- 2nd November 1997State one method used to try to maintain biodiversity.
- 3rd November 1997Explain, using the reactivity series, why attaching blocks of zinc to the hull of a steel ship helps prevent the steel from rusting.
- 4th November 1997Why is graphite soft and slippery?
- 5th November 1997Explain the difference between a strong acid and a concentrated acid.
- 6th November 1997A reaction between calcium carbonate and hydrochloric acid produces 72 cm3 of carbon dioxide gas in 30 seconds. Calculate the mean rate of reaction.
- 7th November 1997Name the type of biological molecule formed when amino acid monomers join together by condensation polymerisation.
- 8th November 1997Describe, in terms of wavelength, the difference between the radiation the Earth receives from the Sun and the radiation it re-emits from its surface.
