1. particles are arranged in a random fashion ANS Amorphous solids 2. physical properties of solvents that are dependent on the concentration of the solute present and the identity of the solvent but not on the identity of the solute. They include vapor pressure, freezing point and boiling point ANS Colliga- tive properties 3. heterogeneous mixtures which appear to homogeneous one-phase mix- tures but are actually composed of particles too small to be seen with the naked eye ANS Colloids 4...

strongest interparticle force out of all the states of matter? ANSWER: solids weakest interparticle force out of all the states of matter? ANSWER: gases What are the 2 types of pure substances? ANSWER: compounds and elements What are the two types of mixtures? ANSWER: homogeneous and heterogeneous Define a pure substance ANSWER: a substance with uniform composition, meaning that it will have the same properties regardless of the size of the sample or where the sample is taken De...

Describe the difference between a pure substance and a mixture. - Pure Substance is an element or a compound; a substance with a fixed chemical composition. Mixture is a combination of two or more pure substances. Examples of Pure Substance - Gold - Au Diamond (Carbon) - C Water - H₂0 Methane - CH₄ Examples of Mixtures - Ocean Water Air Rock Alloy Fabric Differentiate between a heterogeneous and homogeneous mixture - Heterogeneous mixtureComponents unevenly distributed Homogeneous mixtu...
