lesson 4-unit 2 Acids, Ethers, Amides, and Polymers.
Carboxylic Acids- Carboxylic acids, called also organic acids, are group of organic compounds that contain
the carboxyl group as its functional group. This is symbolized as either
Carboxyl groups are al
Lesson 3-Unit 2 Functional Groups
The properties of organic compounds depend on the arrangement of atoms or groups of atoms that are
found within them. An atom or group of atoms that determines the properties of compounds is called a
Trichloroethylene is unsaturated compound. Compounds like TCE contain double or triple carbon-carbon
bonds are classified as being unsaturated
Unsaturated Compounds with Carbon-to-Carbon Double Bonds- some unsatur
Lesson 2-unit 3 Electrochemistry
During 1960s, hydrogen fuel cells were first introduced by NASA to power the onboard electrical systems
in their Gemini and Apollo space capsules. A useful-by product of the hydrogen fuel cell reaction is pure
What is organic chemistry? Study of carbon-containing compounds and their properties. Other than
carbon monoxide, c dioxide, and a few ionic compounds, all compounds containing carbon are organic
Organic chemicals can be extracted from both liv
Molecular Shape and Polarity
1) VALENCE SHELL ELECTRON PAIR REPULSION (VSEPR) Helps to explain and predict molecular shape.
Central atom bonded to three identical atoms will have 120 o bond angles when there are no lone pairs.
A bond angle of 180
lesson 4 - unit 3
Alternative ways to power cars, including unconventional fuels. Most cars use gasoline(which is
mostly octane, C8H18, as their fuel source. Other possible fossil fuels include natural gas (methane,
ch4) and propane, C3H8).
1, Anatomic structure
Assess the benefits to society of technologies that are based on the principles of atomic structures
Write electronic configurations for any element of the periodic table
explain how experimental observations and inferences led to th
Lesson 4- Intermolecular Forces and Their Applications
1) Intermolecular forces- prefix inter means between. Forces that exists between molecules. These
forces cause molecules to attract to each other.
2) Molar mass for H2O is: 16 (O mass) + 1 (H mass) +
Lesson 3- unit 3
Exothermic and Endothermic Reactions
Galvanic cell use the energy associated with electron transfers for many types of batteries, such as those
used to start cars, power flashlights, and run watches and personal sound equipment.
Unit 3- lesson 1 Oxidation Reduction Reactions
Lead contamination in drinking water is a problem facing many Ortario municipalities. This is a major
concern bc exposure to lead can result in brain and nervous system impairments, especially the children.
