PPT-Solutions Chapter 15 Mixtures

Heterogeneous mixture unevenly mixed substance separation can be seen Homogeneous mixture evenly mixed substance no separation can be seen Suspensions Small but visible particles suspended or floating in a gas or liquid heterogeneous mixture. Investigation 1. Let’s talk about our results. Which. mixtures were separated by the screen?. Gravel. Which mixtures were separated by the filter?. . Powder. How are the screen and filter similar?. Investigation 1. Separating Mixtures. Part 1 – Making & Separating Mixtures. Vocabulary. Mixture. – a substance containing two or more materials with different properties.. Property. – a characteristic of an object (something you can observe). Section 1. – Solutions and Other Mixtures. Section 2. – How Substances Dissolve. Section 3. – Solubility and Concentration. 1 - Solutions . and Other Mixtures. . Key Questions. What is a heterogeneous mixture?. Mr. McMartin. Beta Science. Mixtures. Mixture: a combination of two or more substances that are not chemically combined.. Can only become a mixture if they do not react to form a compound.. There are no chemical changes that happen in a mixture.. Mixtures. Solutions are a type of mixture, so to understand solutions, first we have to know what a mixture is…. A . mixture. is a combination of two or more substances. Each substance keeps it’s own properties, even though it is mixed with another substance. They . Separation of Matter Notes. Matter Flowchart. A. Separating Heterogeneous Mixtures. . Based on differences in the size or density of the pure substances making up the . mixture. Decanting. Filtering. Solutions and Other Mixtures. Objectives. Distinguish between heterogeneous mixtures and homogeneous mixtures.. Compare the properties of suspensions, colloids, and solutions.. Give examples of solutions that contain solids or gases.. Mixtures. A combination of two or more substances that do not combine chemically, but remain the same individual substances; can be separated by physical means. Two types:. Heterogeneous. Homogeneous. Chapter 5. Ex:. Melting. Freezing. Boiling/evaporation. Condensation. Sublimation. Dissolving. Bending. Crushing. Breaking. Chopping. Filtration. distillation. Physical change. Does not make a different substance. Grade 5 Quarter 1 Topic 4 . Mixtures . and Solutions. Mary . Tweedy, Curriculum Support . Specialist. . Keisha Kidd, . Curriculum Support Specialist. Dr. . Millard . Lightburn. If a material is pure, it consists of only a single element or compound. If the material is impure, then it is a mixture or contains two or more elements or compounds. Do not be fooled by labels that claim their product is pure… “pure 100% orange juice”. Mixture: a . combination of two or more substances that do not combine chemically, but remain the same individual substances; can be separated by physical . means.. Two types:. Heterogeneous.
