Chem 1010 9/6 – 9/8/2017 Class Notes Area  The area of a plane rectangle = length x width  Area of plane triangle = height x base / 2  Area enclosed by a plane circle = pi x radius 2(squared)  Three Dimensional objects have a surface area Volume, V In three dimensions we are more interests in volume. Volume is a measure of how much stuff you’ve got, a quantity of matter Liter is commonly used for fluids Liter was originally a base unit in the metric system Density Density is defined as mass / volume; d = m / V Water: 1.00 g per mL (1.00g/mL) –NEED TO KNOW- Temperature The volume increases as the temperature increases Celsius 100 C degrees=180 F degrees, 5 C=9 F degrees To Convert to F to C: calculate how many F degrees away from 32F Add or subtract 32 Compounds and Elements -original substance is a compound -if you can’t decompose into 2 by chemical process into 2 or more substances Quicklime from Limestone Lime stone: common gray sedimentary rock -very common -formed from marine organisms Quicklime: is made from roasting limestone -used for making mortar 280 Mt(megaton)(1 t = 100kg Limestone decomposes to quicklime Carbon Dioxide Joseph Black Antoine Lavoisier Combination reaction: Carbon + oxygen  carbon dioxide (-)Burning (reaction with oxygen) = combustion Law of conversation of mass Based on observation, have to of done experiments which then leads us to a conclusion Composition of Compounds Zinc + Oxygen = Zinc Oxide Zinc increases - oxygen increases- quantity zinc oxide increases Law of Multiple Prop
