Question Sixteen • The state of matter that has a definite volume, but no definite shape • Liquid

Question Seventeen • The substance doing the dissolving in a solution • Solvent

Question Eighteen • A physical blend of two or more substances • Mixture

Question Nineteen • A solution containing more solute than can theoretically dissolve at a given temperature • Supersaturated

Question Twenty • A substance that cannot be changed into a simpler substance under normal lab conditions • Element

Question Twenty One • The amount of space that matter takes up • volume

Question Twenty Two • A mixture that is not uniform in composition • Heterogeneous

Question Twenty Three • The substance that is being dissolved • Solute

Question Twenty Four • A mixture that has uniform composition • homogeneous

Question Twenty Five • The amount of matter in a substance • Mass

Question Twenty Six • The amount of a solute that can be completely dissolved in a given amount of solvent at a specific temperature • Solubility

Question Twenty Seven • Anything that has mass and takes up space • Matter

Question Twenty Eight • Composed of two or more substances chemically bound together • Compound

Question Twenty Nine • If I have a mixture of salt and water, is this mixture homogeneous or heterogenous? How would I separate the mixture? • Homogeneous, boil the water off

Question Thirty • Name four ways of separating mixtures • Filter, Evaporate/Boil, Magnet, Pick Out, Chromatography, Distillation

Question Thirty-One • What is chromotography used for? • Separating a mixture, identifying an unknown substance

Question Thirty Two • How do you calculate an Rf value? • Distance solute travels / distance solvent travels

Question Thirty Three • On a chromatogram, if the solvent moved 3.5 cm and the solute moved 2.3 cm, what is the Rf value of the substance? • 2.3/3.5 = 0.66

Question Thirty Four • What does Rf stand for? • Retention Factor

Question Thirty Five • Cold water generally holds more ____________ in solution than hot water • Gas

Question Thirty Six • Is chunky peanut butter heterogeneous or homogeneous? • Heterogeneous

Question Thirty Seven • Is oil and vinegar salad dressing heterogeneous or homogeneous • Heterogeneous
