Every sheet in February 1967
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st February 1967Give one use of nanoparticles and one associated risk.
- 2nd February 1967Give the ionic equation for neutralisation.
- 3rd February 1967State what is shown on a rate graph when the line for the volume of gas produced becomes horizontal (flat).
- 4th February 1967Explain why carboxylic acids are described as 'weak acids'.
- 5th February 1967Name the two gases produced by photosynthesis and the substance it consumes alongside carbon dioxide.
- 6th February 1967State the equation for gravitational potential energy.
- 7th February 1967Name the change of state when a liquid becomes a gas throughout the liquid, at its boiling point.
- 8th February 1967Radium-226 (atomic number 88) decays by alpha emission. State the atomic number of the nucleus formed.

- 27th February 1967Explain why red-shift observations support the idea that the universe is expanding, rather than Earth simply being at the centre of the universe with everything moving away from it.
- 28th February 1967Why does active transport require energy?
