Understanding Mixtures: Definitions, Types, and Examples in Chemistry

This text explores the concept of mixtures in chemistry, distinguishing between heterogeneous and homogeneous mixtures. It defines what a mixture is, explains the characteristics of solutions, suspensions, and provides examples of each type. Additionally, it features a riddle involving compounds like KBr and H2O2, prompting students to identify the components and their quantities. The document serves as a guide for students to better understand the nature of mixtures and their applications in science.

  1. In Question How many atoms of each element are in each compound? KBr… How many K? Br? H2O2… H? O? NaBO3 JUST DO IT 4.2.13 Daily Riddle

  2. Today in your notebooks

  3. Mixtures (Right) Mixture: two or more elements in which a physical change takes place. (Chem change = compound) 2) Homogenous: the same uniform appearance and composition throughout (solutions) Heterogeneous visibly different substances or phases. (suspension) 3) Solution a homogeneous mixture of two or more substances. A solute is dissolved in a solvent in a physical change. These substances do not undergo a chemical change, and they can be separated again. • What is a mixture? 2) What are the two different types of mixtures? 3) What is a solution?

  4. Types of mixtures Def. & Example • Mixture • Heterogeneous • Homogeneous • Solution • Suspension

  5. On the LEFT SIDE of your notebook, write a detailed paragraph defining and explaining the different types of mixtures. 5 MIN • Define mixture • List the two types of mixtures (homo-solution, hetero- suspension) • Explain what each type of mixture is like and give an example of each

  6. Exit slip 1. Which of the following is an example of a heterogeneous mixture? A. Bottled water B. Table salt C. Salt water solution D. Trail mix 2. Which of the following is an example of a homogeneous mixture? A. Water B. Sandwich C. Chocolate Chip Cookie D. Kool aid 3. Oil and water is an example of a(n)… • Solution B.
