This very short week, we simply focussed on the electrolysis of aqueous solutions and their products
Since we are starting a new section about electricity in chemistry, our lessons this week focussed on electron flow, electron position in various types of structures, and electrolysis of ionic salts.
This weeks lessons focussed on rates of diffusion , a summary of particles, and an introduction to how electricity works.
Since its such an important topic, this week covered mole calculations in gases and in titrations, as well as a look at SI units of measurement in chemistry
This weeks lessons were all about moles and mole calculations of various sorts.
This week was about chemical formulae for covalent and ionic substances, and balancing chemical equations.
This week was spent learning more about molecular formulae and using past exercises to check knowledge and introduce new concepts about atoms and ions.
Recap covalent and ionic molecules and valency
Revise and recap atoms, molecules and compounds, and metallic bonding
