You will complete eight required core practical activities if you are studying GCSE Chemistry, and 18 if you are studying GCSE Combined Science (five of these are in Chemistry).
You could be asked questions about the apparatus, methods, safety precautions, results, analysis and evaluation of these experiments.
There are no core practical activities in the Key concepts in Chemistry section.
These questions have been written by Bitesize consultants as suggestions to the types of questions that may appear in an exam paper.

Give two reasons why hazard symbols are used on containers in the laboratory. [2 marks]
Describe the difference between a hazard and a risk. [2 marks]
