LOL, can you sound any more suspicious?

Hey, I'm competing with you for chemistry moderator. :p Thread-stalking is a must! The description of commercial radioisotope production isn't, well, a description of commercial radioisotope production. :rolleyes: It's only telling you how technetium-99m is made. You just need to know that...

Monitoring and Management, the first section. I don't remember seeing it in an exam. :p

Haha, that's like my boyfriend. Except I also happen to have a maturity of a 4-year-old so we're doing juuuuuuuuust fine. :p Good idea, sleep on it. Don't do something you'll regret. Think about it this way - if you stay friends, you can have as long as you like (well, as long as he still...

Well, honestly, I didn't revise anything after year 11 finished. I have to admit I studied extremely hard during the second half of year 11 and I made sure I understood every chemistry concept we were taught. If you can understand everything so that you are able to solve problems using skills...

Are you scared of being hurt by him? If you don't feel comfortable with dating just yet, make it clear to him and the two of you can still be friends. I'm guessing you're 17 or 18. Around 5 years of age difference is still quite big when we're still young. I don't know either of you so I...

Remember that the HSC is the other 50%. If you ace it, you can get way above 76. :)

Oh dear, even they're not sure. :p

Lol, I was thinking the same thing!

Looks like your one is right.

You can always shove it in Winplot to check. :p Here, I did it for you.

Find where the graph crosses the x and y-axes by substituting y = 0 and x = 0 into the equation. Derive the equation and use d/dx = 0 to find stationary points, then use the second derivative to determine whether they are maximum or minimum points.

Edit your posts instead of creating new ones! :p

Not all commercial radioisotopes are transuranic, and not all transuranic radioisotopes are commercial. The difference between the production of the two is with transuranic, you bombard target nuclei with neutrons or charged particles to see what you end up with that has an atomic number of...

Thank you.

ln = loge.

Yeah, I asked our Resident Chemist and Mitochondria (both of them know what they're talking about) and they told me that it's grey-green. Then I asked my tutor, who has been a chemist his whole life, and he said it's creamy white turning to brown, which is what CC says. In desperation, I...

Cyclotrons and linear accelerators are used for bombarding with charged particles, and nuclear reactors bombard with neutrons. This is enough for the syllabus, which requires you to know how transuranic and commercial radioisotopes are produced - all you need to say is neutron or charged...
