Chemistry PapaPodcasts
by Papapodcasts
The following video podcasts are science concepts based on Science Curriculum with a focus on the Chemistry unit on the Periodic Table, Naming Chemicals and Writing Formulas, Balancing Equations and Identifying Different Types of Reactions. These lessons are to be downloaded to your computer for assistance in homework or reviewing older material just prior to your final examination in the course. Mr. Papadimitriou is a high school Science/Math/Credit Recovery teacher in Scarborough, Ontario, Canada. I am presently looking for any sponsorship or financial aid for my high school as we are steering towards being designated an M.S.T School (Math/Science/Technology). Any addition assistance, comments and donations, contact Mr. P at [email protected]

STS: Formation of Hydrate Lab - 8:14
Link to Lap Report: http://bit.ly/hXrYav Please print this lab report and bring it with you on the day that you will be conducting this lab in class. STS: Student Teaching Students: The Labs Safety Cindy welcomes Hot Jazz, Cool Dani, and Master James to help her explain the procedures involved…

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 of polyatomic comes to mind when you look at the non-metal oxide
-
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 end products are CO2 and H2O along with the metal bonded to the carbonate) i.e:...
-
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 the following 4 rules: i.) ____ate ions…

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 that REACTANTS are to the left of the arrow and PRODUCTS...
-
2.01 - Electron Dot Diagram - 4:18
Valence electrons
-
3.08 - Covalent Compounds - 14:25
KEY TERMS: 2 or more non-metals Prefixes: mono, di, tri, tetra, penta, hexa, hepta, octa, nona, deca
-
3.04 - Polyatomic Ions - 14:06
KEY TERMS: 2 or more non-metals, Nick the Camel ate a Clam for Supper in Phoenix, "ate" ending Underlined letter represents the atom # of consonants = # of oxygens # of vowels = # of negative charges associated with polyatomic Ending is "ate" - except for ammonium ion and hydroxide ion 5 Step…

3.02 - Naming Ionic Compounds - 5:48
KEY TERMS: reverse cross over rule, metal, non-metal
-
3.03 - Transition Metals -14:40
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 2 oxygens, name changes to hypo____ite ion. **NOTE: the charge of…

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 oxygen) Formulas for Combustion...
-
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 - we know what that is
-
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 switch places. If the LONELY metal is lower in the...
-
1.09 - Groups in the Periodic Table - 4:44
KEY TERMS: alkali metals, alkaline earth metals, halogens, noble gases, octet rule, cations, anions, metals lose electrons, non-metals gain electrons
-
1.08 - Atoms vs. Ions - 9:34
KEY TERMS: cation = positively charged atoms (metals) anion = negatively charged atoms (non-metals) metals lose electrons, non-metals gain electrons
