Chemical reactions and investigations
Chemical reactions: we know they're happening all around us. But chemical reactions aren't all the same!
We will investigate (which will include some practicals and recording of experimental observations) a few main types of chemical reactions: combination/synthesis reactions, decomposition reactions, and single- and double-displacement reactions. By the end of this unit, you will be expected to have learned how to:
- classify chemical reactions from experimental observations and/or equations
- write word equations and balanced symbol equations
- predict the formation of a precipitate using solubility rules
- provide explanations that use chemistry vocabulary, symbols and conventions (including names and formulae)
Through completing this unit, students will be prepared for an internal assessment worth 4 credits (AS90947).
We will carry out various practical chemistry experiments wherein we'll collect, process, and graph data to identify the relationships between various factors (temperature, concentration, surface area, and presence of a catalyst) on the rate of a reaction.
