Unit 1 CHEMISTRY OVERVIEW: Matter and Measurement Important Concepts 1. Be able to correctly read (interpolate) a graduated measurement and report it to the correct accuracy (10% of increment). 2. Notes on Chemical Safety Video. 3. Identify laboratory apparatus and location of safety equipment in the classroom. 4. Apply the relationship between mass and volume to determine the density of a substance. mass Density . Use appropriate laboratory equipment to find the density of an object. volume 5. Differentiate between mass and weight. Mass is the amount of matter in an object, while weight is the gravitational force exerted on that object. 6. Use SI units to express quantities. Common base units are length (m), mass (g), volume (L), and temperature (°C). Demonstrate understanding through application and how to use a prefix with it. 7. Know the order of metric prefixes and their values. [MKHDODCMMNP] 8. Use conversion factors (equivalence statement) to change from one unit to another. [Want over have] 9. Solve conversions for how answer looks [Bigger/Smaller], Conversion factor, and final answer. 10. Be able to distinguish between qualitative and quantitative measurements. 11. Know the difference between and extensive and intensive measurement. Density is a physical itensive property, whereas weight is an extensive property that varies depending on the strength of the gravitational field in which the respective object is placed. 12. Define chemistry as the study of chemicals, their properties and the reactions in which they are involved. 13. There are three types of change: physical, chemical and nuclear. Physical change is usually associated with a state change, no change in reactant properties. A chemical change is associated with change in reactant properties. Classify the properties and changes of matter as either physical or chemical. Use evidence to identify the type of change. 14. Identify the three states of matter (solid, liquid, gas); define the states in terms of definite/indefinite shape and volume. 15. Matter can be classified as a pure substance or a mixture. Pure substances can be elements or compounds. Compounds have to include more than one type of element (H2O). Compounds differ from mixtures in that they are chemically bonded through a chemical reaction. Elements may exist as single atoms or as molecules. Anytime two substances interact by physical (not chemical) means it is called a mixture. Mixtures may be homogenous (same throughout) or heterogeneous (different throughout.) Skills: 1. 2. 3. 4. 5. 6. By the end of the unit, you will be able to: Be familiar with the symbols on the periodic table of the elements. Define chemistry and be able to describe matter and know how it is classified. Know mass, weight, conversion factors, physical and chemical properties and density. Distinguish between atoms, elements, compounds, mixtures, and homogeneous and heterogeneous. Use laboratory equipment safely and skillfully. Be able to convert metric measurements
