Someone upload the MCQ pls... I didn't take it home :(

Urgent industrial Q: how do we model the first part of the Solvay process? (Co2 bubbled through ammoniated brine)

Alternating b-glucose monomers :D

Do I put a square bracket [ ]n around the 3 monomers? Or the middle one

How do you guys draw your structural diagram for a polymer? Just [one unit]n? Do we have to include the initiator? I'm confused about whats on the left and right

The HSC takes it as after. But conq. chem if I recall says before. Go with what HSC wants though

alright gg band 5 for me. i must have english problems if im the only one that doesnt understand it

Care to explain? My understanding is that strong/weak acid is the degree of ionisation in solution of an acid. This had no meaning before Arrhenius' theory. (e.g. What does degree of ionisation in solution matter for Lavoiser's definiton?) Edit: To clarify what I mean, the answer is saying...

http://www.boardofstudies.nsw.edu.au/hsc_exams/hsc2006exams/pdf_doc/chemistry_06.pdf Wtf Q11... I would have never gotten the answer (check BOSTES answers I don't want to spoil here). If anything those concepts are the result of Arrhenius' definition not that Arrhenius explained them

SSH what are you plans for today? Taking it lightly? I'm just going through responses in my head and then checking with marking guidelines. Nearing the end of the day I'm going to start memorising my notes

Count the other ones too :)

When there are 2 possible molecular formulae for the same isomer, the one with least sum of numbers take preference

It's fine. This discussion was on BoS a while ago. HBrO was old syllabus and then they allowed Br2(aq) and old teachers didnt adapt

"And what do you mean? They want structural diagram?"

Really my friend was saying liquid for the product since its insoluble in water. And what do you mean? They want structural diagram?

What's the states for the addition reaction bromine experiment? C6H10(l ) + Br2(aq) --> C6H10Br2 (aq ?)
