[Catalist] Reminder to Chemistry teachers as they finish off WACE

[Mark Gargano (St Joseph's School - Northam)]

Hi Leon,


Many thanks for pointing out these subtle fresh nuances and sharing them around, very much appreciated, even if just an appropriate nudge in the right direction for those that are ear deep in admin 😉.

All the best to your crew.

Regards,

Subject: [Catalist] Reminder to Chemistry teachers as they finish off WACE


Greetings to all.

This email is a friendly reminder to all of the Y12 Chemistry teachers out there. I am writing this in my capacity as CAC representative to STAWA.

There have been some alteration to the Chemistry Syllabus which will be examined in this year. SCSA would have contacted you by their usual mechanism for this 11 to 12 Circular, etc.

In case you have forgotten, or missed it , here is a summarised update. (Teaching is after all a job with 2n tasks and n amount of times, and the art to survival is where to hide the bodies ! Maybe you missed it because you were sick, overloaded, tied up in admin ...)

The highlighted portions are the new parts in 2021. I have used Microsoft Word's "compare documents" (as an ex Unix (Solaris and Linux) programmer, I knew that Microsoft must have had an equivalent to "diff" !) to generate these changes.

I hope this timely reminder helps you with revision, sorry to all the other poor teachers who are not fortunate enough to teach Chemistry and who have to read this, scroll on by !



Oxidation and reduction

Spontaneous redox reactions can be used as a source of electrical energy, including primary, cells (for example, the Leclanché cell), secondary cells (for example, the lead-acid accumulator) and fuel cells. (for example, the hydrogen fuel cell). Fuel cells are a


·       a range of reactions involve the oxidation of one species and reduction of another species, including metal and halogen displacement reactions, and combustion and corrosionin both limited and excess oxygen environments



·       corrosion of iron is an electrochemical process that can be prevented by a range of techniques, including by exclusion of oxygen and/or water and through cathodic protection and sacrificial anodes


describe the use of electrolysis in electrolytic cells are used in a range of industrial situationsrefining, including metal plating and the for purification of copper, and metal electroplating, including for silver



·       industry produces a vast range of plastics, including addition polymers (for example, polyethene, and polytetrafluoroethene) and condensation polymers (for example, nylon and polyethylene terephthalate [PET]) which have different properties and uses

the varied structures of different plastics due to characteristics, including cross-linking, chain length, and intermolecular forces leads to a range of distinct properties and consequent uses (for example, the different structures, properties and related uses for polyethene, polytetrafluoroethene, nylon and polyethylene terephthalate [PET])


Enjoy !
