Question paper
Written by AcePapers
Independent practice paper written for revision. Not an official Pearson paper and
not affiliated with or endorsed by Pearson.
Time allowed: 1 hour 30 minutes Total: 80 marks
You will need
• A scientific calculator and a ruler. A data sheet is printed after this page and a
periodic table is printed at the end of the paper.
Instructions
• Answer every question. Write your answers in the spaces provided.
• For multiple-choice questions, mark one box with a cross (☒). If you change your
mind, put a line through that box and cross your new answer.
• Show your working in calculations and give units where appropriate.
• In questions marked with an asterisk (*), marks are also given for a clear,
logically ordered answer in which points are linked together.
• The number of marks for each question or part is shown in brackets. Use it to
judge how much to write.
