Every sheet in January 1996
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st January 1996Why do elements in the same group have similar chemical properties?
- 2nd January 1996Why is the amount of product directly proportional to the amount of limiting reactant?
- 3rd January 1996Using the values in the previous question, calculate the overall energy change for the reaction.
- 4th January 1996State the catalyst commonly used in the Haber process.
- 5th January 1996A solution forms a green precipitate with sodium hydroxide solution. Which ion is present?
- 6th January 1996Give the equation for wave speed and its units.
- 7th January 1996A resistor of resistance 15 ohm is connected to a 6.0 V supply. Calculate the current flowing through it. Use V = I x R.
- 8th January 1996Why does reducing the volume of a gas increase the pressure even though the molecules do not speed up?
- 9th January 1996Define the term 'vector quantity' and give one example.
- 10th January 1996Name the type of electromagnetic wave used to treat cancer by killing cells in a tumour, and state which part of the atom emits it.
- 11th January 1996State one difference between a moon and an artificial satellite.
- 12th January 1996Give one risk of stem cell treatment.
- 13th January 1996Why does a potometer measure water uptake rather than transpiration directly?
- 14th January 1996Why does the rate of photosynthesis fall at very high temperatures?
- 15th January 1996Define phenotype.
- 16th January 1996Explain why large-scale deforestation increases the concentration of carbon dioxide in the atmosphere.
- 17th January 1996State the four stages considered in a life cycle assessment.
- 18th January 1996Why does simple molecular carbon dioxide have a much lower melting point than giant covalent silicon dioxide?
- 19th January 1996Define oxidation in terms of electrons.
- 20th January 1996State two units that the rate of a reaction can be measured in.
- 21st January 1996Name the type of biological molecule formed when amino acid monomers join together by condensation polymerisation.
- 22nd January 1996State two long-term stores of carbon that removed carbon dioxide from the early atmosphere.
- 23rd January 1996A 3 kg object is raised 2 m. Calculate the gravitational potential energy gained. (g = 9.8 N/kg)

- 25th January 1996A GM tube detects a count rate of 240 counts per minute from a source. After 15 days the count rate has fallen to 30 counts per minute. Show that this data is consistent with a half-life of 5 days.
- 26th January 1996A radio wave has a wavelength of 3 m. Calculate its frequency, given that all electromagnetic waves travel at 3 x 10^8 m/s in a vacuum.
- 27th January 1996Explain why electricity is transmitted through the National Grid at a very high voltage rather than at the voltage used in homes.
- 28th January 1996Name the structure in a plant cell that controls the substances entering and leaving the cell.
- 29th January 1996State two functions of bile.
- 30th January 1996What is an antigen?
- 31st January 1996Name the chemical released at a synapse that carries the signal across the gap.
