About Grade 10 Chemistry in the Ethiopian curriculum
Grade 10 Chemistry shifts from Grade 9's atomic-structure foundations into reaction chemistry: stoichiometry, solutions, key inorganic compounds, energy changes and electrochemistry, metals and nonmetals, and a first introduction to hydrocarbons — the entry point to organic chemistry.
Topics covered
- Chemical reactions and stoichiometry
- Solutions
- Important inorganic compounds
- Energy changes and electrochemistry
- Metals and nonmetals
- Hydrocarbons and their natural sources
Notes on PrepX
Topic-by-topic study notes anchored to the official Ethiopian textbook. Designed for the building phase — before past-paper drilling becomes productive.
PrepX covers every Grade 10 Chemistry chapter with notes and quizzes matched to the official textbook, including worked stoichiometry calculations. There is no national Grade 10 exam, so there is no Grade 10 Chemistry past-paper archive.

Notes are the foundation phase: do not skip them, do not skim them. Strong notes mastery is what makes past-paper drilling productive instead of frustrating.
Chemical Reactions and Stoichiometry is the chapter that sets the tone for the rest of Grade 10-12 Chemistry — balancing equations and mole-ratio calculations reappear in every subsequent reaction-based topic, so get comfortable doing them by hand, repeatedly, rather than pattern-matching solved examples. Hydrocarbons and Their Natural Sources is a short chapter but disproportionately important: it's the first real exposure to organic chemistry, which Grade 11-12 expand substantially.
