- [Stoichiometric Calculations](https://www.hlayiso.com/grade-11/physical-sciences/notes/quantitative-aspects-of-chemical-change/stoichiometric-calculations) — Stoichiometric Calculations A balanced chemical equation is like a recipe: it tells you exactly how much of each ingredient (reactant) you need and how much product you will get. Stoichiometry is the…
- [Limiting Reagents & Percentage Yield](https://www.hlayiso.com/grade-11/physical-sciences/notes/quantitative-aspects-of-chemical-change/limiting-reagents-and-percentage-yield) — Limiting Reagents & Percentage Yield In theory, chemical reactions go perfectly — every reactant is fully consumed and converted into product. In reality, one reactant often runs out first, stopping…
- [Concentration & Empirical Formula](https://www.hlayiso.com/grade-11/physical-sciences/notes/quantitative-aspects-of-chemical-change/concentration-and-empirical-formula) — Concentration & Empirical Formula Chemistry often involves solutions — substances dissolved in water. Being able to calculate the concentration of a solution is essential for stoichiometric work.…
