Every sheet in July 1970
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st July 1970Name the giant covalent structure made of carbon in which each carbon atom is bonded to four others.
- 2nd July 1970Convert 250 cubic centimetres into cubic decimetres.
- 3rd July 1970A student heats solid copper carbonate strongly in a test tube, and it breaks down into copper oxide and carbon dioxide.

- 12th July 1970State three factors that increase the rate of diffusion.
- 13th July 1970Describe how phagocytes destroy pathogens in the body.
