What is an Equilibrium Reaction?

If you’re studying HSC Chemistry, you’ve probably started to encounter equilibrium reactions. From our tutoring courses in the summer holidays, I realised that this can be a challenging topic for many students. Hopefully this article will clear up misconceptions and cement your understanding of the concept.

HSC Physics: The Slingshot Effect

The slingshot effect is used by a spacecraft in increase its velocity. To do this, the spacecraft travels close to another moving object such as a planet or moon. As the craft moves away from the planet, it is travelling faster than when it started. However, it is vitally important to realize that its speed relative to the planet is unchanged, only its speed relative to the sun (and other planets orbiting the sun).

Biopolymers: Guide to a Band 6 Answer

Biopolymer questions are often a source of trouble for HSC Chemistry students. Every student should have a biopolymer which they can name and describe briefly, but often they don’t have enough information for a 5 or 6 mark question. This guide will make sure you are confident to answer any possible question on biopolymers.

Understanding Titration for HSC Chemistry

/
As an HSC Chemistry tutor, I observe titration to be a particularly long and confusing process for many students. This article will break down the logic behind each step of the titration process, and furthermore, provide guidance on performing calculations related to titration. It will also run through major cautions that HSC Chemistry students need to be aware of in performing titration.
HSC Biology 2014 question on evolution by natural selection

Get full marks on questions about natural selection

/
In almost every HSC and HSC trial paper for Biology, there is a question on evolution by natural selection which requires you to describe the process, and often apply it to a real or theoretical situation. This can range from "explain the process of evolution by natural selection" to more roundabout questions using models for natural selection based on cookie jars. Regardless, this question will always be there and there is no reason you should ever get less than full marks - providing you follow this simple guide.
