Over the five days of spring break, we’re coming in to wrap up topic 6 and get familiar with some new tools. Session #1 – Review topic 6 concepts (6.01-6.04) Session #2 – Quiz on topics 6.01-6.03 Session #3 – Quiz on 6.04, 6.05 Discussion Session #4 – 6.05 Wrap […]

Spring Sessions

In this topic, we cover the essential aspects of a successful chemical reaction in terms of reactants colliding.  We will also introduce the Arrhenius equation, which connects the rate constant to the temperature and activation energy for a reaction. To earn experience for the work, go to Mission 6.04. Learning […]

Day 79 – The Arrhenius Equation

We will continue our look at the rate equation today by examining the graphs that are generated by reaction concentration over time.  In addition, we will consider the concept of half-life of a reaction and how that also connects to the rate data and graphs. For experience, master Mission 6.03. […]

Day 78 – Graphing Rate Data

Understand how rates are determined is important, but we need to be able to describe how each reactant contributes to the overall rate of a reaction.  For this, we will determine rate equations, known as rate laws, and the order (exponent) for each reactant. To get experience for this work, […]

Day 77 – Rate Laws

It is time to break down the various aspects of chemical reactions and time.  In this mission, we will focus upon the methods of measuring reaction rates and the factors that can influence the rate of a reaction. To get experience for this work, go to Mission 6.01. Lesson Objectives […]

Day 76 – Kinetics Intro

Our exploration of atomic structure, energy, and bonding theories has come to a close.  Today we will organize the concepts we’ve seen and put in a little bit of extra practice to help us prepare for the coming exam. Learning Objectives Develop a quick reference for the topic 5 exam […]

Day 75 – Topic 5 Review

We’ve already taken a brief look at the forces of attraction between molecules.  Today we will practice some of these key ideas and try to cement it into our brains. For experience on this work, complete Mission 5.11. Learning Objectives Identify the intermolecular attractive interactions (dispersion, dipole–dipole, hydrogen bonding, ion–dipole) […]

Day 74 – Intermolecular Forces

Now that we know the shapes that form from electron pair repulsions, it’s time to look into what has to happen in order for the pairs to be evenly spaced to form the molecular geometries that we’ve seen. This is all about hybridization of orbitals. In this mission, we will […]

Day 73 – Hybridization

This activity is designed to help us visualize the bonding and geometry necessary to perform some reactions. Lesson Objectives Use molecular modeling kits to help visualize bonds. Use bond energies to find enthalpy of reactions. Agenda (10) Warm-Up/HW Check (5.08 mastery, 5.09 completion) (90) Modeling Kit Lab (20) Modeling Recap […]

Day 72 – Modeling Kits

Today we will begin looking at the way molecules come together and form the specific shapes that influence their external bonding. To gain experience for this work, go to Mission 5.09. Lesson Objectives Predict the three-dimensional shapes of molecules using the VSEPR model. (9.2) Determine whether a molecule is polar or […]

Day 71 – Molecular Shapes & Polarity
