Summary

• Description:

  The PDF document comprises STAREHE GIRLS' CENTRE Chemistry Paper 1 Pre Mock Exam with Answers (Marking Scheme). The marking scheme is in a different document.

  It was a Pre-mock Chemistry Paper 1 (Theory) examination.

  This paper provides rigorous coverage of general, physical, organic, and inorganic chemistry concepts across the secondary syllabus. It challenges students on stoichiometry, chemical equilibrium, reaction mechanisms, electrochemistry, and qualitative analysis.

  • Duration: 2 Hours
  • Total Marks: 80
  • Number of Questions: 27 (Questions 1 - 27)
  • Structure: A single continuous section consisting of 27 compulsory structured, numerical, and short-answer questions.

  It covers the following topics:
