Primary amiDe, quite a difference .

I assume this percentage is a percentage of the total mass. If so, you also have the mass of your sample before and after the drying. You can now state that the mass of the sample after drying is equivalent to the amount of moles of K3Fe(C2O4)3 times it's molar mass. So with many moles of K3Fe(C2O4)3 did you start out? You also have the mass of the water you removed. How many moles of water does that give you? Now you know the ratio of moles of water:moles of K3Fe(C2O4)3. If you can calculate that to the ratio of moles of water:1 mole of K3Fe(C2O4)3, you are done

You might say it equals to 1/T

Some questions on names and purposes of some molecules
Fuzzwood replied to D'Nalor's topic in Organic Chemistry
Your previous one: (E)-(2-((4-((4-(cyclobuta-1,2-dienyloxyimino)-3-hydroxy-1,2-diazetidin-3-yl)fluoromethoxy)-1,2-diazetidin-3-ylaminooxy)ethynylthio)tetrazetidin-1-yl)(1,2,3-oxadithietan-4-yl)methanethione I am NOT gonna bother figuring out which is which, it was amusing however, seeing the name getting built as i was drawing the molecule. And with your revisions: (E)-(4-(((2-((4-((cyclobuta-1,2-dienyloxy)methylene)-3-hydroxy-1,2-diazetidin-3-yl)fluoromethoxy)cyclobutyl)methoxy)ethynylthio)-1,2-diazetidin-3-yl)(oxetan-2-yl)methanethione -
Just have fun getting laid for presenting a quick and easy solution

People who actually think that way should be shot on sight. Survivors should be shot again. This to purify the gene pool.

Determination of water in toluene - simple test needed

Portable conductivity meter. I know they use a similar technique when measuring the water content of brake fluid when your car is in the shop. -
oxygen scam....do our cell tissues really benefit?

Peroxide can rapidly form radicals and damage the DNA in such a severity that it can result in cancer. -
Then you also need to know what a mole is. Google is your friend.

What don't you like about SFN?

You need to have a set number of constructive posts first. The restriction is to keep out ppl like you tbh -
Impurities can sometimes be organic stuffs, but can also be iron salts. Can't you simply distill it? It will also get rid of colorless impurities.

For zinc? Sure, but I am not sure for the other metals. I know they should theoretically by wise of standard electrode potentials. But I am not sure if the acid is able to eat through the oxide layers of the other 2 metals.

Depends on the catalyst really. In acid catalysed esterifications, the acid reacts with the carbonic acid to form an intermediate.

Some questions on names and purposes of some molecules
Fuzzwood replied to D'Nalor's topic in Organic Chemistry
Same trick as that other branched cross you made: 4,4-di(penta-1,4-diyn-3-yl)-3,5-diethynyl-1,6-heptadiyne But alkanes get boring, throw some rings and N,O,S in it -
Some questions on names and purposes of some molecules
Fuzzwood replied to D'Nalor's topic in Organic Chemistry
1) propan-2-ylidene 2) 1-propen-2-yl 3) penta-1,4-diyn-3-yl 4) hepta-1,2,5,6-tetraen-4-yl 5) ethynyl -idene exit = the link to the main chain is a double bond, triple bonded carbons can never have sidechains -

Some questions on names and purposes of some molecules
Fuzzwood replied to D'Nalor's topic in Organic Chemistry
pentan-3-yl and pentan-2-yl, the number in this case defines the carbon linked to the higher chain. As to what your written compounds are used for, no clue. They make interesting molecules to name however. (And to be honest, i let a pirated but otherwise $2000 dollar software figure out the last 2 molecules ) -

First: 6-isopropylundecane Second: 6-(2,4-dimethylpentan-3-yl)undecane Third: 6,6-bis(2,4-dimethylpentan-3-yl)undecane Fourth: 4,4-bis(2,4-dimethylpentan-3-yl)-3,5-diisopropyl-2,6-dimethylheptane On the first: sack your teacher because he forgets the longest-alkane rule. Or was this a homework exercise? -
As you were told MANY TIMES BEFORE, the pump pumps water INTO the oil well, it DOES NOT suck the oil up.

Because we consider a single cell life as well. Look at single-cellular life forms.

Life begins at conception. But abortion should still be legal because that life is NOT sustainable before a certain fetal age.

I was actually pointing at the overuse of smileys, thank you very much. And do you know that most of the insults given actually apply more to the giver than to the receiver?
