Lab Exam 1 covers the following labs: Laboratory Safety and Basic Lab Techniques, Math review/Dimensional AnalysisIdentification of Substances by Physical PropertiesNomenclatureThere are 25 question. You have 120 min to complete this test. Questions will be a mixture of free response, true/false, fill in the blank, and/or multiple choice. Lab test will not be the exact replica of topics/questions given in study guideLaboratory Safety and Basic Lab Techniques, Math review/Dimensional AnalysisSafety concerns Purpose of exhaust hoodsProper way to dispose broken glassMean and average deviation from mean calculations (ex # 4, pg # 20)
Finding mass and volumeSignificant figures, scientific notation, standard formDensity—conceptual and calculations Conversions (0°C to F and K and vice versa, Kg to Pound and vice versa, gm-kg, ml-l and vice versa etc.)
Practical lab procedures
How do you find the volume or read a graduated cylinder
Unit analysisIdentification of Substances by Physical Properties
ID a substance based on physical propertiesDifference between physical and chemical properties and example
What does it look like to be soluble or insoluble (Use table 1 pg # 38 to answer this kind of questions)?
Density (Density= mass/volume) and how density decides if something is going to float or sink
Practical lab procedures— how do you find the density of unknown solid or liquid?
