December 2013 - GCSE Science 5-a-day
Every GCSE Science sheet published in December 2013, with answers. Biology, chemistry and physics recall, definition and calculation, drawn from every strand.
Every sheet in December 2013
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st December 2013Write the formula of calcium chloride and explain the ratio.
- 2nd December 2013Explain why aluminium cannot be extracted from aluminium oxide by heating with carbon.
- 3rd December 2013Hydrogen reacts with chlorine to form hydrogen chloride: H2 + Cl2 -> 2HCl. Use the bond energies given to calculate the overall energy change for this reaction. Bond energies: H-H = 436 kJ/mol, Cl-Cl = 243 kJ/mol, H-Cl = 432 kJ/mol.
