This resource is designed for students to practice free radical substitution in terms of both understanding the rationale for each step (initiation, propagation and termination) and also how the write the correct equations for each type of equation using multiple examples.

This resource is designed for students to be able to define key parts of the solubility topic in GCSE and iGCSE Chemistry within solubility. Students should use two different solubility curves to obtain data. There are 14 questions and answers at the bottom of the sheet that focus on these key points of specifications: Defining Solubility and other key terms Interpreting and analysing data from solubility curves

This resource is designed for students to fully understand the difference between molecular and empirical formula and work between different calculations. The resource is divided into multiple sections where it gets progressively challenging. It involves working out the molecular formula using the empirical formula and Mr and calculating the empirical formula from masses or percentages. This resource is suitable for both iGCSE and GCSE specifications.
