Hon Chemistry 2-6-23 Chapter 9 Test Overview & a Look at Advanced Problems

HON CHEMISTRY: I still say stoichiometry is a lot like baking – sometimes you just have to get in there and get your hands dirty! Here is our overview of the test from today and a look at a couple of of the advanced stoichiometry problems. I also found the rusted iron problem work all the way out from last year, so I’m posting that below as well.

Again I want to emphasize – the majority of the test is basic reaction stoichiomety, limiting reactants and percent yield. Be sure and give that the most of your study time!

Also, review writing and balancing chemical reactions. Most of the stoichiometry problems will require that you begin by doing just that! There will be just one extra jumbo large problem. You’ve got this!! ๐Ÿ™‚

Hon Chemistry 1-25-23 Limiting Reactant Review & Lab Heads Up

CHEMISTRY: Great job with the limiting reactant problem today! Remember a couple of things – for each problem, you know it’s a limiting reactant problem when they give you the amounts of two reactants, so you are going to have to work TWO different stoichiometry problems. At the end, the reactant that gives you the least amount of product is your limiting reactant. Label it! Also, that answer is the right amount of product. Box it!

And speaking of finding limiting reactants, lets do it for real in lab tomorrow. Will you be ready?

Hon Chemistry 1-24-23 Limiting Reactants

HON CHEMISTRY: So if you have 11 roller wheels, how many roller blade skates can you make? You know, really, limiting reactant is almost that simple. Well, the concept is anyway! You deal with limiting reactants in your life all the time. Now we’re just applying that same concept with chemical reactions! ๐Ÿ™‚

  • Hon Chemistry 1-11-23 Double Replacement & Combustion Reactions

    HON CHEMISTRY: We had to go fast, but do you realize what we did? We finished all 17 types of reactions today! We’ll practice them tomorrow since we had to go so fast today.

    Careful when you work with any of these! For all single replacement reactions and reactions involving forming or decomposing oxide, be sure and refer to the Activity Series. Yes, you do get to memorize the Activity Series for the test – for the big test, not for the coming up quiz!

    Are you working on memorizing all 17 types of reactions?! But don’t just memorize them. Make sure you can apply them as well. When you start to work any equation, first determine what type of reaction it is, then figure out what rule applies and follow it to determine the products. I believe in you! You can do it!! (and yes, I realize I am repeating myself, but I do and you can!)

    Hon Chemistry 1-10-23 Single Replacement Reactions & the Activity Series

    HON CHEMISTRY: Moving right along with the 17 types of chemical reactions, here are the single replacement reactions – and you also got a head start on the activity series!

    This makes 15 reactions so far, and we’ll do the rest tomorrow. Careful though, memorize, but don’t just memorize them. Make sure you can apply them as well. When you start to work any equation, first determine what type of reaction it is, then figure out what rule applies and follow it to determine the products. I believe in you! You can do it!!

    Happy New Year 2023!!

    Happy New Year!! Aren’t you glad that God gives us a chance to start all over again?

    We are going to have an awesome 2nd semester!! I’m praying that God will use this semester to help get you ready for the incredibly wonderful things in has for you in the future!! And more than that, I pray that this year you’ll grow more than any other in your walk with our Lord Jesus. I pray that you’ll be determined to follow Him, no matter if you have to walk by yourself.

    I can promise you – Jesus will never forsake you!

    Happy New Year!!

    โ€œAnd they that know thy name will put their trust in thee: for thou, LORD, hast not forsaken them that seek thee.โ€ Psalm 9:10

    ….โ€I have decided to follow Jesus. No turning back, no turning back. Though none go with me, I still will follow. No turning back, no turning back.โ€ John Clark

    Science Exams First Thing Wednesday – December 14

    God bless you as you study for your chemistry, honors chemistry, and physics exams! How are you studying? Best advice? Practice, practice, PRACTICE! Be active in studying – don’t just read over the material. Review games on the online textbook, reworking old homework problems, re-working those flash cards you’ve made – all good. Watching vodcasts of old lectures might not hurt either!

    Chemistry Exam Help Session Wednesday morning, 7:20 A.M. for Regular & Honors Chemistry. As always, it’s come and go.

    IMPORTANT – Bring your exam review packet to the chemistry room before you go to your exam room!

    Here are the room assignments for Thursday’s exam:

    Chemistry 1 Rm 130 (Mrs. Crowder’s Room)
    Chemistry 2 Rm 131 (Mrs. Milligan’s Room)
    Chemistry 4 Rm 132 (Mrs. Stinson’s Room)
    Chemistry 7 Rm 133 (Mrs. Heun’s Room)
    Hon Chemistry Rm 134 (Mrs. Trentman’s Room)
    Hon Physics Rm 100 (Mrs. Tunnellโ€™s Room)

    Don’t forget to bring your completed exam review packets to our classroom first thing when you come on Wednesday. I’m praying for you!!

    “Fear thou not; for I am with thee: be not dismayed; for I am thy God: I will strengthen thee; yea, I will help thee; yea, I will uphold thee with the right hand of my righteousness.” Isaiah 41:10

    Hon Chemistry 12-1-22 Describing Chemical Reactions

    HON CHEMISTRY: So tell me again – how do you know if a chemical reaction has occurred? And how could you record that for someone? Here’s the lecture from today on writing balanced chemical equations.

    Here’s another hint – it’s not necessarily a good idea to try to make your own blue flame thrower! Click here to watch the Periodic Videos Blue Flame Thrower Video
