IGCSE Chemistry — Frequently Asked Questions
What topics are in IGCSE Chemistry?
IGCSE Chemistry covers: Principles of Chemistry (atomic structure, bonding), Chemistry of the Elements (periodic table, reactivity), Organic Chemistry (hydrocarbons, polymers), Physical Chemistry (rates, equilibrium), and Chemistry in Society.
How do you balance chemical equations?
To balance equations: 1) Write the unbalanced equation, 2) Count atoms of each element on both sides, 3) Add coefficients to balance atoms (never change subscripts), 4) Check all atoms are balanced.
What is the reactivity series?
The reactivity series orders metals by reactivity: K, Na, Ca, Mg, Al, Zn, Fe, Pb, H, Cu, Ag, Au (most to least reactive). More reactive metals displace less reactive ones from solutions.
How many papers are in IGCSE Chemistry?
Edexcel IGCSE Chemistry has two papers: Paper 1 (2 hours, 110 marks) and Paper 2 (1 hour 15 minutes, 70 marks). Both are written exams covering all topics.
What equipment do I need for IGCSE Chemistry?
For the exam: pen, pencil, ruler, and calculator. You should know common lab equipment names and uses (beaker, conical flask, burette, etc.) for exam questions.
