Happy with my marks, band 6 in everything but english lol. 99 in software :music::music:

I'd love to come!

I did a bit of maths for this Q...

I've attached some working, hmu if there are still any outstanding issues.

I can't wait to not worry about King Richard III and creative writing after this Thursday! :music: also its been a year but @Bob99 did you get a band 6 in chem?

I only did it for the sake of clarity and demonstration. I wrote digital notes so prefer the use of bold, italics, underline, and yellow highlighting.

I drew the railroad for the example above. Remember that railroad diagrams uses lines to indicate the flow of syntax and repetition (the {0 or more repetitions} or [optional part]). If you need any more clarifications or help let me know!

The syllabus states we need to know complexation reactions to determine the presence of 8 cations. barium (Ba2+), calcium (Ca2+), magnesium (Mg2+), lead(II) (Pb2+), silver ion (Ag+), copper(II) (Cu2+), iron(II) (Fe2+), iron(III) (Fe3+) The one that I remember is the Iron (III) thiocyanate...

I found this in the Pearson Chem textbook (dm me if you need a copy): Transition metal ions are small and highly charged. This high charged density results in an ability to strongly attract anions/small polar molecules (ligands), forming a complex ion. The process of ligands forming an...

If you need further explanations on any of the other symbols of EBNF or help on questions let me know! I'll try write something similar for railroad diagrams later today.

I'll try explain EBNF here, Its basically the text version of Railroad to explain the syntax of a programming language (most HSC questions on EBNF would be to either interpret EBNF or translate given code into EBNF). I'll run an example and indicate what each symbol means...

B was the correct solution, A is the mass of the Copper in the solid and is not the total mass of solid (I forgot the mass of the carbonate lol)

This is my working, with it getting A as a solution.

Was the solution A?
