May 1958 5-a-day
Every sheet in May 1958
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st May 1958Why does simple molecular carbon dioxide have a much lower melting point than giant covalent silicon dioxide?
- 2nd May 1958Define oxidation in terms of electrons.
- 3rd May 1958State two units that the rate of a reaction can be measured in.
- 4th May 1958Name the type of biological molecule formed when amino acid monomers join together by condensation polymerisation.
- 5th May 1958State two long-term stores of carbon that removed carbon dioxide from the early atmosphere.
- 6th May 1958A 3 kg object is raised 2 m. Calculate the gravitational potential energy gained. (g = 9.8 N/kg)
- 7th May 1958Calculate the energy needed to melt 0.50 kg of a substance with a specific latent heat of fusion of 210000 J/kg.
