Equilibrium

Chemistry lecturer Stuart Bailey takes us through equilibrium, with a focus on buffers: what they are, where they are found, what they are used for, and how to make them.

Electrochemistry

Lecturer Stuart Bailey discusses electrolytic and galvanic cells, explaining what they are and what they’re used for, as well as the important similarities and differences between the two.

Organic Chemistry

Associate Professor Mauro Mocerino talks us through some key elements of organic chemistry that are vital to remember, and also has a look at some questions you might get in your exams and the best way to go about answering them.

Chemical Reactions

Associate Professor Mauro Mocerino explains what to consider when asked for an observation, highlights the difference between an equivalence point and an end point in a titration, and makes limiting reagents a little easier to understand.

Bonding and Polarity

Curtin’s Head of Chemistry Mark Buntine discusses the various forms of bonding, including covalent, ionic, and metallic bonding, and also examines important concepts such as electronegativity. In the second half of the video In this second video, Professor Buntine takes a look at the various methods available to determine the shape and polarity of a molecule, including Lewis Structures and VESPR, and gives detailed examples of how exactly to apply them.

Intra and Intermolecular Forces

Professor Mark Buntine revises important relevant info from the Bonding and Polarity videos, and then addresses the different types of intermolecular forces, including dispersion forces and dipole-dipole forces. In the second half of the video Professor Buntine examines hydrogen bonding, ion-dipole interactions, and the physical attributes of these and other intermolecular forces. He also goes into detail regarding the properties one of our most important molecules: water.

How to use Differentiation to solve equations

How can you tell how fast a plane will be travelling four hours after take off if you know where it is? You use the mathematical measure of differentiation to figure out how much one variable (eg: velocity) is affected by changing another variable (eg: position). Dr Ian van Loosen takes you through the equations used and explains the helpful constant, power, constant multiple, sum and difference rules that you can use to work out even the most trickiest of questions. Part 1 of 3.

Product & Quotient Rule Tutorial (Differentiation Part 2)

How do you calculate the slope of a tangent line especially when any point on the curve is a result of several different variables? Dr Ian van Loosen explains how to use the product and quotient rules of differentiation to find out the answer. This is the 2nd part of a 3 part series.

Trigonometric Functions & Chain Rule (Differentiation Part 3)

When complex problems arise, no one, not even mathematicians want to spend days working out the answers. Dr Ian van Loosen explains some of the quicker ways to solve complex differentiation problems by using the chain rule and the derivatives of trigonometry functions. The last part of a 3 part series,

How to use Trigonometry for solving the angles & side lengths of Right Angled Triangles

Trying to figure out how to solve a right-angled triangle, but aren't up-to-speed with trigonometric functions? Fear not. Curtin University's Dr Ian van Loosen, with the help of a woolly mammoth, explains simply and clearly Sine, Cosine or Tangent and then how to use the functions to solve a triangle. This is the first video in a series.

How to solve Non-Right Angled Triangles using Sine

To solve a non-right angled triangle you need apply the sin or cosine rule depending on what info you have. In this second video of the series, Curtin University's Dr Ian van Loosen defines the sine rule and works through an example.

How to solve a Non-Right Angled Triangle using Cosine

Oblique triangles are some of the hardest to solve. Which Law of cosine do you use? What if you don't know any of the angles? In this third video of the series, Curtin University's Dr Ian van Loosen explains how to solve triangles when you have three side lengths, no angles or two side lengths with an enclosed angle.
