Hon Chemistry 1-28-21 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! πŸ™‚

  • Chemistry 1-28-21 Thursday’s Assignment

    CHEMISTRY: Today in class you’ll be practicing writing balanced chemical equations from word equations. If you are Zooming, the worksheet you need is here:
    Balancing Equations WS 1a

    Work neatly! If you need to, do your scratch work on notebook paper and then transfer your balanced equation to the worksheet. If you can’t print the worksheet, you can write the balanced equations on notebook paper. Skip lines between the equations.The worksheet is due Monday.

    Final hint – be sure and check the chemical formulas before you balance the equations!!

    Chemistry 1-26-21 Describing Chemical Reactions

    CHEMISTRY: So you learned last semester how to determine if a chemical reaction has taken place. How would you go about describing a chemical reaction to someone? Here’s our discussion from today on writing balanced chemical equations!

    First step in writing equations? Make sure you can write chemical formulas! First step to that? Memorization!!

    So tell me again – how do you know if a chemical reaction has occurred? Here’s another hint – 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

    Chemistry 1-20-21 Chapter 7 Test Practice

    CHEMISTRY: Here’s our practice with oxidation numbers and chemical formulas and a couple other things from Wednesday. What about polymers? Have you watched that vodcast? Super important!!

    Are you using the Chapter 7 Stuff to Know sheet? Be sure and use it as a road map for your studying. I know it seems like a lot, but you can do it!

    First priority – make sure that you have memorized EVERYTHING. Then, practice!!! Go to sciencegeek.net and make sure you can write and name chemical formulas. Practice, practice, practice!!! Then start practicing the different kinds of problems – do at least three of each one of them. And also try those on sciencegeek.net. That’s always some good practice. And don’t forget about polymers!

    Chemistry 1-19-21 Chapter 7 Test Overview

    CHEMISTRY: God bless you as you study! Here’s our overview of the test from today and a look at some chemical names and formulas. Did you find the Chapter 7 Stuff to Know sheet? Be sure and use it as a road map for your studying. I know it seems like a lot, but you can do it!

    First priority – make sure that you have memorized EVERYTHING. Then, practice!!! Go to sciencegeek.net and make sure you can write and name chemical formulas. Practice, practice, practice!!!

    Chemistry 1-15-21 Polymers & Empirical & Molecular Formulas HW

    CHEMISTRY: We finally finished the chapter! Did you realize molecules could be that large? And so many of them. But don’t you think polymers are cool? The first vodcast below is the rest of the lecture that you need for polymers. Fast forward to the part where we left off in your class. Some items for contemplation: why are certain plastics recyclable and others not…and what about dishwasher and microwave safe? Hmmmmm…

    Below that is what we actually did first in class yesterday – our look at the homework from last night – empirical and molecular formulas. Great stuff to review as you study for the test!
