CHEM 1151K Study Guide - Midterm Guide: Bromine, Fluorine, Atomic Number
Document Summary
Chapter 2: how to convert temperature units k= c + 273. 1 and f= (1. 8 x c) + 32 and c= ( f . 32)/1. 8: metric conversions using the correct number of significant figures, how to calculate density, mass, volume from the density formula d=m/v or m=dxv or. Make sure you know what elements exist as diatomic molecules. Most elements are solids at room temperature; diatomic molecules include hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine; there are 2 liquids (bromine & mercury), gases include n, o, f, cl & all noble gases: chemical formula h so . Chapter 4: distinguish between chemical changes and physical changes physical changes can be determined without changing the substance & can include color, odor, taste, state, melting point & burning point. Chemical changes describe the substance"s ability to react. & form new substances and including rusting, burning, and combustion: chemical equations: what are reactants, what are products reactants are the substances you start with.
