Hon Chemistry – Chemical Formula Worksheet 2

HON CHEMISTRY: Happy Fall Break! I hope you had a great day today!! Here are the first (just in case you need another copy) and the second chemical formula worksheets. Did you ever decide if you want to have a help session? Just let me know! (P.S. I hope you are getting to sleep late!)

Chemistry 10-9-12 Mixture Separation Lab

CHEMISTRY Wow! That was pretty insane, huh? Did your salt look like this? I’m really, really proud of you and the way you were able to apply what you learned in the last chapter about mixtures and physical means of separation!

It’s a good thing to be able to follow a set of directions, but an absolutely TREMENDOUS thing to be able to figure out how to solve a problem on your own! That’s a difficult thing to learn how to do, and you are doing a great job developing that skill. Any questions about writing up the lab report for TOMORROW? Use the Lab Report manuscript form you can find here under the chemistry labs tab, or on Edline. Remember, some of you definitely need to elaborate on your procedure!

Also, you must include the data table that is on the original lab sheets, and then include your own observations of each step you did after the data table. And then, after you write your own conclusion, don’t forget to answer all of the questions at the end of the lab sheets. The answers to those questions will go after your own conclusion.

Hon Chemistry 10-9-12 Oxidation Numbers

HON CHEMISTRY: So how are the chemical formulas coming? I think you’re starting to get the hang of writing the formulas, but what about naming compounds? Help session? Don’t forget to add a few more things to your “make sure you memorize for the test” list: polyatomic ions, chemical names and formulas for common substances, binary acids, oxyacids, prefixes, and oxidation rules. Oxidation rules! We’ve really already been using oxidation numbers, you just didn’t know it! 🙂

But does it all matter? These complicated rules about naming compounds, I mean. Let’s find out tomorrow in lab!

Chemistry Make-Up Labs

Hey guys, don’t forget that make-up labs for regular and honors chemistry have been rescheduled for this coming Monday afternoon at 3:30 P.M. and Tuesday morning at 7:15 A.M. Let me know if you have a lab to make up so I can have the materials ready for you.

Hon Chemistry 10-5-12 Binary Molecular Formulas

HON CHEMISTRY: Okay, I’m not saying that learning to name and write chemical formulas is as bad as a jellyfish sting (you’ll get that in a minute if the thumbnail ever refreshes!), but you do have to really, really pay attention to the details!! Here’s the lecture from Friday on writing formulas and names for binary molecular compounds. Part of it’s really similar to what you learned to do last week for ionic compounds, don’t you think? The other part is totally different, though!

Make sure you keep everything straight. Find a way to organize all the information for yourself so you won’t get confused. Also, don’t forget the lists you have to memorize, especially the one for MONDAY – polyatomic ions!! And practice, practice, practice!!!

Hon Chemistry 10-4-12 Chemical Formulas Encore

HON CHEMISTRY: So is it a little clearer now? Did today’s homework review help? Here it is, just in case you need to save it for the future.

Also, for a bit more guided practice – spend some extra time with the review activities at www.sciencegeek.net! How’s the worksheet coming? A covalent compound means the same thing as a molecular compound – don’t let that mess you up. You’re doing great!! 🙂

Physics Test on Chapter 3, 2-D Motion

PHYSICS: So you ready for that test tomorrow? Since I forgot to turn on the mic at the help session this morning (!), I thought I’d post an old review from the Projectile Motion worksheet problems (I think it’s #3, 5, and 7). Don’t forget what you should do to start – Draw a picture, write what you know, resolve the resultant velocity into vertical and horizontal if you need to, and find formulas that fit (because it will hardly ever be solved with just one) and go for it!!

If you are talking angular projectiles, the resultant velocity is actually made up of two things – horizontal velocity and vertical velocity. The horizontal velocity never changes, the vertical velocity has a different direction going up and coming down, but it has the same speed at equal levels. If you’re talking horizontal projectiles, the resultant velocity is the same as the horizontal velocity of the gun – or whatever, because that’s the only kind of initial velocity it has! Relative motion is even easier – just use the Pythagorean theorem and tangent, and use horizontal to find horizontal and vertical to find vertical. Good luck! I’ll be praying for you!!

Chemistry 10-4-12 Chapter 1 Test

CHEMISTRY – Are you ready? Good luck studying! Here’s the overview of the test that we did in class today. Did you like the videos? If you’d like to watch them again, you can find them at www.periodicvideos.com.

Make sure you aren’t just reading your book and notes. First, memorize the facts, then go back and make sure you can apply the concepts. Study examples, make your own examples, practice making questions. And don’t forget, if you are getting lost with everything you need to know, or if you’re not sure how to study, click here for the Chapter 1 Stuff to Know & Study Suggestions sheet.

Also, don’t forget the great review games that are in the Student Premium section of the online textbook. You can do this – I believe in you! I’m praying for you!!

Chemistry 10-3-12 Elements & Element Handbook Search

CHEMISTRY – Well, we did it! We finally finished chapter 1. Here’s the last of the notes on elements. How’d you do with the Element Handbook Search? You can ABSOLUTELY count on that information being on the test, so make sure you get that back from me tomorrow!

Hey, have you had a chance to check out the Chapter 1 Stuff to Know and Study Suggestionssheet? Great info there! And don’t forget about the interactive review games with the online textbook. Good stuff!

Have fun with the Observing a Candle lab tonight! Holler if you have any questions. Be sure and list your observations in two columns like it shows on the sheet – but on a separate sheet of paper. And don’t forget to douse the candle in water at the end!

Hon Chemistry 10-3-12 Formulas with Polyatomic Ions

HON CHEMISTRY: Are you starting to see numbers in your sleep? Here’s the lecture from Wednesday on writing chemical formulas with polyatomic ions. The same………but different? Tons of memorization for this chapter – monatomic ions, polyatomic ions, and this is just the beginning. Are you working on the list of chemical names and formulas for common substances that’s due Friday?

Here’s the change in tonight’s homework: Pg. 240 – 244, 2 – 8, AND ADD 17, 18, 41, 44. Good luck, and keep practicing!!!
