  1. I should have added the caveat of if she chooses to do it in Brisbane. I don’t actually know if the Gold Coast campuses offer science, but UQ requires high school chemistry or physics in addition to a particular stream of math to get in. My understanding of the OP was that she either didn’t meet those requirements or it’s been so long that any knowledge that was there is gone now. It’s very common. As I mentioned, the major unis offer bridging courses in the case that the entry requirements aren’t met. If they have been, then I know at least at UQ they offer a high school equivalent chemistry course as a first year offering, which is a great course for people in her position taught by excellent staff (no points for guessing which uni I went to). I’m sure QUT would have something similar, and probably Griffith as well. They all have academic advisors available who can help her figure it out.
  2. As the only one here with direct experience with where the OP is from and the universities she has access too, I can tell you that she will need chemistry just to get into the degree, and will almost certainly need to do one or both first year chemistry courses.
  3. I wouldn’t worry too much about OP, really what matters is your commitment to studying and doing the work. I’ve known plenty of middle of the road OP students do very well once they hit uni. I don’t know where in QLD you are, but QUT and UQ in Brisbane both have bridging courses you could look at doing to help fill the gap in your knowledge and tick off any pre requisite boxes you haven’t ticked. They can be fast paced, but my experience tutoring students in it is that if you spend enough time practicing questions and going over the content, you’ll come out of it fine. Speak to the universities and see what they say. There are a lot of resources available if you are struggling, including access to free counselling if you need it.
  4. I believe any volatile compound it dissolves in is fine then, just so long as it’s fully evaporated before you place it on the agar.
  5. If they’re soluble in buffer, is it possible to instead measure MIC with microbroth dilution? I’ve never been a great fan of disk diffusion personally. There are just too many other things that can influence zone of inhibition.
  6. ! Moderator Note Sorry, but this is complete gibberish. Moved to trash. I would strongly encourage you to look into what frequency actually means and how it is used in science.
  7. Side note: they believe that because the LNP and Murdoch press convinced them to believe it, presumably to detract from their own accountability in all of this. It simply wasn’t / isn’t the Greens policy. A topic for another thread, however. Certainly, fuel reduction has been an issue. I mentioned this elsewhere, but after the Black Saturday fires in 2009, it was identified as such, but nothing has been done really. However, it’s only one factor of many, and it’s short sighted you say that it will fix the issue going forward. It is not a cure all, and it doesn’t always work (but it can help). The reason climate change is implicated is because as it gets hotter and drier, the presence of undergrowth no longer really matters - the fire will spread anyway. There is an article on the ABC that I thought was well laid out that covers the topic. https://www.abc.net.au/news/2020-01-10/hazard-reduction-burns-bushfire-prevention-explainer/11853366
  8. Some targets look deceptively easy just because they're small. You received some synthetic advice over on Chemical Forums that looks good, so I won't bother too much with that. I would add a small word of caution that sometime you end up sinking more time and money into making a target than what you would have spent if you just bought it. This compound is commercially available and quite cheap. Alfa sells 5 g for a bit over $23. I don't know where you are based or what resources you have access to, but were I your position, I would just order it.
  9. The point of determining the oxidation state is really just so you can determine what number to put in brackets. In your case, so you know that it is iron(III) oxide and not iron(II) oxide. You've already shown how you got to the oxide part.
  10. It was over 2 years ago, there’s really no point. I more meant why do need this specific chemical in such amounts? There are certainly cheaper and easier ways of learning about synthesis.
  11. No point. I have no idea why they did it. You mean like a discussion forum like this one? Chemical forums is good. Can I ask what you're needing this stuff for?
  12. I have ordered things from random Chinese companies in the past, and I did in fact receive what I wanted, but their packaging and labelling leaves much to be desired. I received 10 grams of a beige power in a zip lock bag (!!) with a totally different label on it. The declaration for customs said it was something that it wasn't, which is obviously illegal. It was definitely worth it for the price ($600 instead of $3k), but we won't order from them again. I've had friends order antibodies from other companies there and receive them fine, but the packaging said that they were shipping empty tubes. Like I said, you can order from them at your own risk.
  13. Yes, though I wouldn't recommend directly copy pasting from another website when their background is quite so blue if you don't want to be caught out plagiarising (I assume that came from here https://lavelle.chem.ucla.edu/forum/viewtopic.php?t=23108). You should try and think about it yourself next time.
  14. Did you not already explain what is wrong with it in your first sentence?
