Curtin 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.

Curtin University lecturer Stuart Bailey talks about electrolytic and galvanic cells. He explains what they are and what they’re used for, as well as the important similarities and differences between the two.

Curtin University’s 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.

Curtin’s Head of Chemistry Professor Mark Buntine talks about the various forms of bonding, including covalent, ionic, and metallic bonding, and also examines important concepts such as electronegativity.

Curtin’s Head of Department Professor Mark Buntine revises important information from the Bonding and Polarity videos, and addresses the different types of intermolecular forces, including dispersion forces and dipole-dipole forces hydrogen bonding, ion-dipole interactions, and the physical attributes of these and other intermolecular forces. He also explains the properties of one our most important molecules: water.

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).

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.

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.

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

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 the third video of this series, Curtin’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.
