funny how quickly he got banned

yeah, oxidize oxalic phthalate ester with hydrogen peroxide. it will form phenol and carbon dioxide but the cyclic intermediate (1,2-dioxetane-3,4-dione) is formed and luminesces. as well, you could use zinc sulfide or a nice powder mixture of Al2O3, SrO and Eu2O3 for a green colour or Al2O3, SrO and Dy2O3 for a blue colour

How to find compound by knowing mass and percentage composition
budullewraagh replied to umer007's topic in Applied Chemistry
according to my second definition i am correct:\ i think that in this case, you can be pretty much certain. think of it: ____O_____O ____||____|| H-O-S-O-O-S-O-H ____||____|| ____O_____O (peroxydisulfuric acid) that would not work, as there are 2 missing H. this means that two doubly bonded oxygen atoms (one on each side) would have to break one of its bonds and form a bond with hydrogen, thus reducing the sulfur from a +6 formal charge to a +5 formal charge, which isn't too likely. my prediction is that IF this were to be formed, it would be very unstable and would be quite a strong oxidizing agent. thing is that the peroxide bond would probably break and bond to hydrogen before the doubly bonhded oxygen would reduce to form O-H -
im sorry man but they arent

How to find compound by knowing mass and percentage composition
budullewraagh replied to umer007's topic in Applied Chemistry
that is debatable and, "Saying that diatomic hydrogen is a compound would be like saying that a 10-gram crystal of sugar is a different compound than a 1-gram crystal of sugar. The only difference is the amount of the same ingredient." that only applies if i were to have said that diatomic hydrogen is different from monatomic hydrogen. actually, monatomic hydrogen doesn't exist, essentially i have another definition: "A pure, macroscopically homogeneous substance consisting of atoms or ions of two or more different elements in definite proportions that cannot be separated by physical means. A compound usually has properties unlike those of its constituent elements." -
nah, it would be a waste. i'd have to go for some cesium

haha yeah. hey, it's a high quality reagent. i should put it to good use, as i have a bunch of it

maybe he did lose

sorry buddy but hydrogen is a diatomic molecule. according to merriam webster a compound is: "2 : something formed by a union of elements or parts; especially : a distinct substance formed by chemical union of two or more ingredients in definite proportion by weight" sorry buddy -
aaaah careful man. dont get cancer or anything

Chemical Composition of Common Materials

theres less astatine...or at least thats what they want me to think. actually come to think of it i just made a kilo of it by instantaneous alpha bombardment of finely dusted uranium intimately mixed with finely dusted bismuth...actually no, but thats a good way to multiply the amount of an element tenfold quickly -
i have to differ. i have 25 year old "muriatic acid" in my basement. it was 20%. it now fumes HCl when i open it and is supersaturated, no joke. i also must differ in opinion with regard to the statement that HCl is "ionically" bonded in the gaseous state. it really is quite relative to opinion. i would personally call it quite polar covalent

what a terrible existence. i can't even remember if i slept last night or not. i wasnt necessarily asking for work to copy per se, but i was asking for a few prods in the right direction

agreed. um, hydrogen anyone? good, now what about nitrogen? oxygen? carbon? theyre all really common -
ah, but the socialist countries are hardly socialist when such actions occur

How far should the US take separation of Church and State?

yes, although i believe "religion" is playing far too great of a role in american politics -
How to find compound by knowing mass and percentage composition
budullewraagh replied to umer007's topic in Applied Chemistry
carbon needs 4 bonds, oxygen needs 2, hydrogen needs 1. carbon is the "backbone" so to speak. add the hydrogen and you leave 2 bonds that still need to be made. then add the oxygen and hey, you have formaldehyde -
you know, i would do that except it is midnight and i have to do a physics lab first, then write an english paper, write maybe 5 pages of bio, then do a packet of questions for bio. all in all i'm thinking 5 hours of work in total. sad thing is that ive been working since i've come home but i came home late because i was busy representing my school at a competition for "smart" people. i could not have done anything last night because i had a physics test today and i was away for 5 hours after school due to a concert. ie, life is hell tonight. thank you for your help

convert each of the elements to moles, then determine the ratio of the various components -
hokay so tarzan is trying to save jane from an angry-angry hippo. he quickly climbs a tree and swoops down on a vine to pick her up and deliver her to the safety of a 9 meter high cliff. if tarzan has twice the mass of jane, how fast must he be going before impact to safely deliver her to the cliff?

not in the least. rather, i believe that cultures should diffuse, but not to an extent where the meaning of culture is lost
