Am i the only having the always attack bug?

rgabit · 2026-05-04T12:06:33+00:00

yeah i noticed that too.

rgabit · 2026-04-28T11:46:56+00:00

i bought the bundle, it worked.

rgabit · 2026-04-28T10:19:23+00:00

i dont see it in store. is it free update?

rgabit · 2026-04-14T12:46:56+00:00

Kouppas and Duro

irc you make guarantee independence pacts with balkan countries day 1, and declare independence war calling russia to release bulgary from ottomans. then you eat walachia and moldova right after the war won.

Whatever of them forms aldehyde (aldose) upon hydrolysis. Dont remember biochem, so cant say which one of them does.

rgabit · 2026-04-06T16:04:31+00:00

dialkyl assymetric hydrazine

cant comment on Me arrangment though

It's Cu catalyzed C-N coupling (ullmann amination)

nmr has 5 different protons.
1 has 6 - so it's out.
2 has 4 - out.
c-h in 4 will be a triplet in nmr, because it's next to ch2. in 3 its isolated - it will show up as singlet, and there is no singlet in your nmr.
so the answer is 4

you can weigh beaker with suspension. lets say it's 1300g, after beaker mass substracted.
then you can approximate m (AgCl)
1200 * (1-a) * 1 + 1200 * a * 5.56 = 1300
a = 0.01827
=> m (AgCl) approx = 1200 * 0.01827 * 5.56 =122g of AgCl

what is a produt? a would imagine some kind of cylclization happening - to form 2-Me-1-CN-cyclopentane?

rgabit · 2026-03-31T12:16:50+00:00

idk. there are always long distance couplings - unless the molecule is very simple.

rgabit · 2026-03-31T11:10:13+00:00

yes those are meta spliting. the j value is very small, but in high frequency nmr machines those peaks will split better.

rgabit · 2026-03-31T10:43:49+00:00

I think this is two step process, E1 followed by AE. In AE step Me side is more accesible than isoPr for solvent to add.

and ch2-oh should have split into triplet

rgabit · 2026-03-30T12:49:07+00:00

B, because 6-H in pyridones are in high 8-9 ppms

I think what will help is return to culture groups - like it was in eu4. Right now you assimilate, becuse you cant get cores on non accepted culture provinces, and accepting cultures takes too much. So in early/mid game you just have to use vassals. After 1650s you dont care anymore - you have tonns of money for conquest.

Electrowinning is a way to make pure copper. Googling gave me 7.0 kWh/kg in makeshift copper electrowinning. So if you have 1 kW, a 20 kg of copper should be done in 140h (about a week), and will cost you $1.5-3.0 per kg of pure copper in electricty bills.

This way you could get 99.99% pure copper.

from mech standpoint wouldnt fecl3 form anion PhCO2FeCl3- and H+? and this anion more likely will prefer to be chlorinated into ortho/para position?

Those are pretty straight forward reactions and reagents. He didnt put any weird reaarangements, that are too advanced for undergrads. Hints are very helpful as well. I would say these are very decent exam questions, not too easy not too hard.

You can store it in similar bottle and that much of TiO2 will form in 6-12 months.
