Study Guide - Unit 1 – Matter Matters Last Unit: Introduction Current Unit: Matter Matters Next Unit: “Making” Matter Part 1 - Directions: Answer the following questions in your notebook. What is the density formula? What is the density of a salt solution if 50.0 mL has a mass of 57.0 g? If the following substances are placed in a container, determine how the substances will arrange themselves: chlorofoam (d = 1.48 g/mL), mercury (d = 13. 6 g/mL), water (d = 1 g/mL), hexane (d = 0.66 g/mL), copper (d = 8.94 g / mL) A rectangular block has the following dimensions of 1.20 cm x 2.41 cm x 1.80 cm and a mass of 28.12 g. What is the density of the block and can the material be gold? (dgold = 19.3 g/mL) The density of dry air is 1.19 x 10-3 g/cm3. What is the volume of 50.0 g of air? What are the four phases of matter and what are their characteristics? Where is the most common place plasma, is found? Distinguish between a physical and chemical property. Provide one example of each. Classify the following as physical property or chemical property. a. blue color b. density c. flammability d. reacts with acid to form H2 e. boiling point f. reacts with a base to form water How is a physical change different from chemical change? Classify the following as physical or chemical changes: a. Sodium hydroxide dissolves in water b. Iron rusts c. Ice melting d. Sugar dissolves in water e. Grinding chalk f. Potassium chloride decomposes to form potassium chloride and oxygen gas What are considered pure substances? How is a mixture different from an element? Different from a compound? How are elements different from a compound? List and define the two types of mixtures. A homogeneous mixture is also called a(n) ____________________________________. Explain how YOU would separate the following mixtures: a. the chocolate from a chocolate chip cookie b. a solution of salt water Classify the following as element, compound, homogeneous mixture, or heterogeneous mixture. Mint Chocolate Chip Ice Cream a big mac baking soda (NaHCO3) Copper Wire Draw and label a phase diagram. Draw and label a heating and cooling curve. (Hint also know the Phase Triangle)   Part 2 - Directions: Read the following information on elements, compounds and mixtures. Fill in the blanks where necessary. Words that will be used to fill in the blanks (Homogeneous, Heterogeneous, Elements, Compounds, Cannot, atom, atoms, Chemically, Periodic Table) Elements: A pure substance containing only one kind of ____________. An element is always uniform all the way through (homogeneous). An element _____________ be separated into simpler materials (except during nuclear reactions). Over 100 existing elements are listed and classified on the ____________________. Compounds: A pure substance containing two or more kinds of _______________. The atoms are _________________ combined in some way. Often times (but not always) they come together to form groups of atoms called molecules. A compound is always homogeneous (uniform). Compounds ___________________ be separated by physical means. Separating a compound requires a chemical reaction. The properties of a compound are usually different than the properties of the elements it contains. Mixtures: Two or more ________________ or _________________ NOT chemically combined. No reaction between substances. Mixtures can be uniform (called ________________________) and are known as solutions. Mixtures can also be non-uniform (called ________________________). Mixtures can be separated into their components by chemical or physical means. The properties of a mixture are similar to the properties of its components. Part 3 Directions: Column A lists a substance. In Column B, list whether the substance is an element (E), a compound (C), a Heterogeneous Mixture (HM), or a Solution (S). (Remember a solution is a homogeneous mixture.) In Column C, list TWO physical properties of the substance. Column A Column B Column C 1. Summer Sausage   2. Steam 3. Salt Water 4. Pencil lead (Pb) 5. Dirt 6. Pepsi 7. Silver (Ag) 8. Toothpaste (Na2HPO4) 9. A burrito 10. Italian Dressing 11. Chicken Soup 12. Lemonade
