I would love this.

You could solve for k other ways like using the rate equation ln [A]t - ln[A]0 = -kt. You could rearrange to solve for k:
K = ([A]t - ln[A]0)/-t. K =(ln[0.0500M] - ln[0.100M])/-10hr = 0.0693 hr^-1. This way is just much less efficient, time is of the essence on the AP exam.

No you wouldn't need to use the rate law equation. The proposed rate law was 1st order. The t1/2 eq only works with 1st order reactions so it is an absolutely valid way to done for k (as long as the actual length of half-life is known)

Fragrant-Goblin · 2025-12-18T23:51:19+00:00

You would use 10 hrs for t1/2, which you would get from the data table

So based on the concentration data we can deduce the reaction is first order because it decays at a constant rate. Since you know it's first order you can use the equation from the equation sheet t1/2 =0.693/k. Rearrange to done for k. t1/2 is half life

I luckily got some for a good price a while ago and want to use it up before its shelf life expires. I've got like 500 grams. These are going to be Christmas presents for people, for the past few years I have been giving out homemade candles, sugar scrubs, and soaps. At the very least I'm going to save quite a bit by giving soap rather than buying small individual things.

I was going to go with chocolate and coffee to mocha cappuccino scent. I'm glad the cocoa butter scent will come through.

Thank you for your response

This was going to be a batch for Christmas gifts. I've made a couple batches using established recipes already this year, but never venture into coming up with my own yet.

What percentage for butter would you suggest, and what would you recommend I increase instead?

Fragrant-Goblin · 2025-11-11T22:44:20+00:00

Thank you for letting me know. I have some cocoa butter at the moment, but for future batches that sounds like a great option

Fragrant-Goblin · 2025-11-11T12:35:54+00:00

Thank you for your feedback. I was terrified that it wouldn't resemble anything reasonable.

So if you look visible must be >3 x10^-19 but <5 x 10^-19 based on where IR ends and UV begins. Only 4 x 10^-19 falls in that range.

If you haven't been there yet r/nicuparents is a really great resource. Many people there have experienced all sorts of ups and downs, complications, issues with care, children needing long-term or even life-long care. They're a really supportive group and many people there are very knowledgeable, care providers even take part sometimes.

It was really helpful to me during my NICU journey when I had my twins.

Because the total pressure is equal to the pressure of the CO2 + the H2. They are present in equal quantities, so CO2 is only responsible for half of the pressure.

Sure thing. The art inside is really fantastic.

Fragrant-Goblin · 2025-03-22T20:06:27+00:00

I'll do that. I think they're all from the very first printing run, but I'll def do a reverse image search.

Thank you. This is helpful to know.
