NoteCourse Portal: Edexcel IGCSE Science (Double Award) - Chemistry Component

Welcome, students! This specialized section contains core study notes, targeted practice question banks, and past exam resources specifically aligned with the Chemistry component of the Pearson Edexcel International GCSE in Science (Double Award) (4SD0) curriculum.

1. Course Introduction

Pearson Edexcel International GCSE in Science (Double Award) (4SD0) is designed for students seeking a broad, dual-credit qualification in science. It encompasses core components of Biology, Chemistry, and Physics. The Chemistry component provides a thorough introduction to chemical structures, reactions, rates, energetics, and basic organic chemistry principles.

Assessment Outline (Chemistry Component)

The Chemistry component of the Pearson Edexcel International GCSE in Science (Double Award) is assessed through a single externally examined paper. Calculators are permitted in the exam.

Assessment Paper Target Curriculum Format & Duration Marks Weighting (Chemistry)
Paper 1C (Chemistry Component) Core Chemistry Syllabus Content Written exam featuring multiple-choice, short-answer, calculations, and structured questions — 2 hours 110 marks 100% (33.3% of overall Science award)

Syllabus Structure

The Chemistry component is divided into 4 core areas:

States of matter; elements, compounds, mixtures; atomic structure; the Periodic Table; calculations (stoichiometry); ionic, covalent, and metallic bonding.

Group 1 alkali metals; Group 7 halogens; gases in the atmosphere; reactivity series; extraction and uses of metals; acid-base reactions; chemical tests.

Energetics (enthalpy change); rates of reaction; reversible reactions and equilibria.

Terminology; crude oil (fractional distillation); alkanes, alkenes; synthetic addition polymers.
