Cheat Sheet
- Mixtures vs. Compounds -
On composition of mixtures practice problems, remember that mixtures are physical blends of substances (like saltwater) and can be separated by physical means, whereas compounds (like NaCl) result from chemical bonding with fixed formulas. Mixtures have variable composition, but compounds obey the law of definite proportions. A neat mnemonic: "Mix and match, compound stays exact."
- Homogeneous vs. Heterogeneous -
Homogeneous mixtures (solutions) have uniform composition at the molecular level (e.g., sugar dissolved in water), while heterogeneous mixtures (suspensions) display distinct phases (e.g., oil and water). The Tyndall effect - light scattering by colloidal particles - is a quick test for heterogeneity (think milk vs. water). Recall "homo same, hetero different" on element compound mixture quiz items.
- Physical vs. Chemical Changes -
Physical changes alter state or appearance without forming new substances (melting ice), whereas chemical changes produce new products (rusting iron). On any physical and chemical change quiz, watch for bond breakage/formation and energy release or absorption. Use the mnemonic "Phase stays, chemistry plays" to cue transformation type.
- Elements vs. Compounds Identification -
Elements consist of one type of atom (O₂, Fe), while compounds combine two or more elements in fixed ratios (H₂O, CO₂). Leverage the periodic table to match symbols and write formulas - Al³❺ + O²❻ → Al₂O₃ is a classic example. Practice with identify mixtures and compounds practice to solidify formula-writing skills.
- Key Separation Techniques -
Common methods for breaking down mixtures include filtration (sand-water), distillation (ethanol-water), and chromatography (ink separation). Distillation exploits boiling point differences, while chromatography uses adsorption and polarity to resolve complex mixtures. Remember FDC - Filter, Distill, Chromatograph - as your go-to trio during chemistry mixture practice questions.
