4 worksheets are included, with answers on a separate page.
Easy-for students at the lower end of a GCSE higher paper (let’s face it 90% of the time the answer is 2) (H2 + O2 H2O)
Medium- for students at the top end of a GCSE higher paper, or for A-level students who have forgotten everything over the summer (PCl3 + H2O P(OH)3 + HCl)
Hard- for A-level, or G&T GCSE (HI + H2SO4 H2O + H2S + I2)
Super hard- best solved using oxidations states, for top A-level students (MnSO4 + NaBiO3 + H2SO4 NaMnO4 + Bi2(SO4)3 + H2O + Na2SO4)
