PPT-Chapter 12 Solutions Types of Mixtures:

THINK SOLUTE PARTICLE SIZE Solutions solute particles too small to see lt1nm Colloids solute particles intermediate in size they remain suspended throughout the solvent 11000nm . 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.. [ & dynamic ] . point processes and big data sets . Mike . West. Department of Statistical Science. Duke University. . cellular phenotypes in vaccine adjuvant studies . Immune response studies. 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. 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. Homogeneous. 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). 2014EdusmartGR 4 Teacher GuideGrade 4Separating MixturesTEKS 45Matter and EnergyThe student knows thatmatter has measureable physical properties and those properties determine how matter is classified
