Review for Final Exam

Key terms and concepts to study for final exam:

·         What makes sunsets red? Light scatters in particles

·         Allotropes

·         Covalent bonds (vs. ionic bonds)

·         Carbon has four covalent bonds:  draw them for CH₄  or C₂H₆

·         Which are the lowest energy electromagnetic rays? Infrared (heat)

·         Photosynthesis is the opposite of respiration. What are the products of each?

·         What is the atmosphere made of?

·         What is 1 atmosphere of pressure at sea level?

·         Define isomers.

·         Explain separating compounds through Distillation by different boiling points

·         What is in rainwater that makes it acidic? CO₂

·         Define CFC’s and what they do to promote global warming.

·         How does carbon dioxide affect global warming?

·         Hydrocarbon boiling points increase as the number of carbon atoms increase. Why?

·         What produces CO2 and what uses it?

·         What is carbon monoxide (CO) and how is it produced?

·         Define a catalyst. Is it used up in a reaction?

·         Define fractional distillation and what it’s used for.

·         How much garbage does the average person create per day? 4-7 pounds

·         What byproducts come from manufacturing processes?

·         Kinetic vs. potential vs. chemical energy

·         Why doesn’t an upside down jar lower into water easily? (air)

·         What does it mean to “use up” chemicals?

·         Altitude is related to pressure. High altitude = less pressure

·         Molarity is solution concentration

·         Kjoules measure energy

·         When we extract a metal from an ore, are we oxidizing or reducing it?

Honorable Mentions & How to make a page tab

On your new blog, learn how to get gifs (see above) and photos imbedded into your blog.
Also, learn how to make new pages with page tabs across the top. You want to post your terms and vocab words on a separate page. Go to Design, Pages, New Page, Name the page "Terms," save, and save arrangement. Also, click 'Show tabs in header.'

Today's honorable blog mentions are:
1. Jilly for her colorful blog background
2. Layla for her diagram of the hydrologic system
3. Merry for her creative story
4. Nora for creating the table shown below aggregating all our foul water data together. (And also for best pun: "It is clear that the carbon step made the clearest water.")
More honorable mentions:
5. Ricardo's drawing and Merry's drawing (see below)



Ricardo's distillation drawing



Merry's distillation drawing


(Who will win mentions tomorrow? Stay tuned.)

Nora's table of 6 lab groups' data for foul water

How can we explain Nora's table? Why did groups Boron and Carbon have less recovered foul water at almost every stage?

How does distillation purify foul water?

Explain the distillation process. How can distillation remove salt from salt water and give us pure, fresh water? How can distillation separate alcohol from water? What do the different boiling points of each liquid have to do with it? What makes liquid change into vapor or gas?
