Chem 103 Exam Topics
Chemical Compounds and Formulas
Naming Compounds
• Use reference tables to name compounds from formulas
• Remember prefixes like mono, di, tri, etc.
• Examples can be found on quizlet
Writing Formulas
• Find chemical names on the periodic table
• Write chemical formulas from names
• Utilize prefixes like mono, di, tri, etc.
Atomic Structure
Parts of an Atom
• Protons = atomic number
• Electrons = same as protons
• Neutrons = mass number - atomic number
• Count these using the periodic table
Isotopes
• Atoms with same number of protons but different number of neutrons
• Watch a video for further clarification
Solution Concentration
Concentration Calculations
• Types: %m/v, %v/v, equivalents, molarity
• Calculate solution concentration using specified formulas
Dilution Calculation
• Calculate dilution of a solution
