5.01 - Synthesis Reactions - 15:18

KEY CONCEPTS: 2 or more reactant --> 1 product metal oxide + water --> base (bases contain an OH-) non-metal oxide + water --> oxy-acid (oxy-acid is a polyatomic with a hydrogen acting as a cation) - see what type...

5.02 - Decomposition Reactions - 5:23

KEY CONCEPTS: 1 reactant --> 2 or more products metal hydrogen carbonate --> metal carbonate + CO2 + H2O (the metal can be any of the metals to the left of the aluminum ladder combined with a hydrogen carbonate. The...

3.06 - Acid Base Nomenclature - 14:48

KEY CONCEPTS: When naming Binary Acids, start by identifying the hydrogen atom as "hydro" and name the non-metal using the "ic" ending and add the word acid. Rules for Oxy-Acids: They are derivatives of polyatomic ions and polyatomic variations. Follow...

3.01 - Writing Formulas for Binary Ionic Compounds - 20:51

KEY CONCEPT: When you combine a metal and a non-metal, use the 5 Step Cross over Rule to put together your formula

4.02 - Balancing Equations - 22:35

KEY TERMS: balance both sides of the equation by placing a number (coefficient) in front of the compound. Don't be afraid to have to change that number if it does not completely balance the equation. Balance polyatomic ions first. Remember...

2.01 - Electron Dot Diagram - 4:18

KEY TERMS: transition metals, Classical system, Stock system, Latin names, Roman numerals, cross over rule, reverse cross over rule "ic" ending = higher charge "ous"ending = lower charge

3.07 - Hydrate Compounds - 5:01

KEY CONCEPTS: Name compounds as usual. After naming the compound include the Greek prefix for the amount of waters present and use the name HYDRATE

5.04 - Double Displacement Reactions - 6:13

KEY CONCEPTS: pairing metals and non-metals metals switch places with the other metal in the reaction Don't forget the 5 Step Cross Over Rule! Don't forget to balance the equation.

3.05 - Polyatomic Variations - 10:14

KEY CONCEPTS: Always refer to the original form of the polyatomic ion. From the original form: _____ate ion, if: i.) you gain an oxygen, name changes to per____ate ion. ii.) lose 1 oxygen, name changes to _____ite ion. iii.) lose...

5.06 - Combustion Reactions - 8:15

KEY CONCEPTS: -these reactions involve burning a hydrocarbon in the presence of oxygen. Hydrocarbons are compounds made by ONLY H and C atoms. 2 Types of Combustion Reactions: i.) Complete Combustion (plenty of oxygen) ii.) Incomplete Combustion (poor supply of...

5.05 - Neutralization Reactions - 7:11

KEY CONCEPTS: -special type of double displacement reaction acid + base --> salt + water REACTANTS acids - either binary acids or oxy-acids (contain H) bases - contain hydroxide (OH) PRODUCTS salt - ionic compound (ANY metal and non-metal) water...

5.03 - Single DIsplacement Reactions - 18:52

KEY CONCEPTS: metals switch with metals** non-metals switch with non-metals **look at the Activity Series if metal would switch with metal. If LONELY metal is higher in the Activity series than the metal paired with the non-metal can the metal...
