This week was all about molecules and matals and non-metals and atomic structure and electron arrangement.

This week was about reversible chemical changes and reactions, with a particular focus on the dehdration of hydrated coppersulphate and cobalt(II)chloride, and ending off with a chemical test for water.

We started the week out learning about crude oil and a basic introduction to organic chemistry, followed by a discussion of intermolecular forces and the complete distillation of crude oil, and ending with physical and chemical changes.

We learned how to separate a liquid from a soluble solid, mixtures of gases, and the principles of fractional distillation

This week was dedicated to finding out the difference between various mixtures in liquids, including solutions, colloids suspensions and the difference between suspensions and precipitates.

We started off this year by finishing off our section on separating and purifying mixtures.

More about electrolysis, general patterns in electrolysis, and real life applications of electrolysis in extracting aluminium metal from its ore, purifying copper, copper plating and other metal plating, and the electrolysis of brine and its importance for making some very…

This week was dedicated to electrolysis, the breaking down of chemicals by passing an electric current through them, and identifying the products that would be formed at each electrode.

This week was more practice with calculations, including how to work out which reagent was used up first in a reaction, and thus how much product could be produced. We also started with atrying to understand the basics of electricity…

This week we learned how to calculate number of moles in solutions and then practised calculations where we had to determine how much (in terms of mass or volume) of a particular reactant or product was used up or created…
