Unformatted text preview: Uremify Chil Matter and Energy How to figure out if somethird is an pound, heterogenous mixture, or homogenous mixture o OILUUUUUU (All matter) Yes A Study Soup Can it be separated by a physical process? Qubstance -Mixture Can it be decomposed by a uniform chemical process? throughout? Compound Heterogenesie Element Homogenous What is matter? Anything that has mass (m) and occpies. spate u Chemistry studies composition, structure, properties of matter and changes it'undergoes N Study SoulStudy Properties of Matter Intensive Properties characterize a pure substance sare independent of the amount of the substance density, hardness, etc. Extensive properties depend on how much of the substance is present in a sample length width mass volume, etc Physical properties can be observed or measured with out changing the substance into another substance - color, texture, density, etc. Chemical Properties >characteristics of a substance that are observed during a chemical reaction (which is when the chemical composition identity of the substance is changed) =combushbility. toxicity, etcSeparating Mixtures Distillation ruses evaporation to separate a component from a mixture the resulting vapor is recovered by condensation used whenever components of a mixture have different volatilities (one or more components more readily vaporizes than others) Filtration separates larger particles from a mixture usidos a medicim to block the large particles from passing through >can be lised with both liquicls and qases Chromatography mixtureus dissolved in a Huick called mobile phase > as the particles intercack more with the other phase, the stationary solide the slower they move u the ones that interact weaker are Faster the different speeds separate them
