November 2001 - GCSE Science 5-a-day
Every GCSE Science sheet published in November 2001, with answers. Biology, chemistry and physics recall, definition and calculation, drawn from every strand.
Every sheet in November 2001
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st November 2001Explain, in terms of electrons, why reactivity decreases going down Group 7.
- 2nd November 2001On what property are elements ordered in the modern periodic table?
- 3rd November 2001In the equation 2H2 + O2 gives 2H2O, how many moles of water are formed from 3 mol of hydrogen?
- 4th November 2001Explain, in terms of bonds, why breaking bonds is an endothermic process.
- 5th November 2001The forward reaction of a particular reversible reaction is exothermic. State whether the reverse reaction is exothermic or endothermic.
- 6th November 2001Why must dilute nitric acid be added before silver nitrate solution when testing for a halide ion?
- 7th November 2001State the equation for work done.

- 10th November 2001State what the gradient of a distance-time graph represents.
- 11th November 2001Explain why ultraviolet, X-rays and gamma rays can be hazardous to human health, but radio waves are not.
