SCH3U — Grade 11 Chemistry (Ontario)
SCH3U is Ontario's Grade 11 university-preparation chemistry course, following The Ontario Curriculum, Grades 11–12: Science (2008). This page is your map: each of the five units below links straight to the ChemistNate notes that cover it. If you are new to chemistry, start with Unit A — matter, bonding, and the periodic table are the foundation everything else is built on.
How to use this page: find your current unit, open its notes, work the examples, then try the practice problems at the bottom of each page. Every page on this site is free to use and share.
Unit A: Matter, Chemical Trends, and Chemical Bonding
Atoms, the periodic table, trends, bonding, and molecular shapes — the vocabulary of chemistry.
Unit B: Chemical Reactions
Balancing equations, the five reaction types, reactions in water, and redox.
Unit C: Quantities in Chemical Reactions
The mole, molar mass, and stoichiometric calculations.
Unit D: Solutions and Solubility
Concentration, solubility, colligative properties, and the solubility product.
Unit E: Gases and Atmospheric Chemistry
Gas laws, the atmosphere, ozone, smog, and acid rain.
