NaOCl + CH3OOH + Fe + H2O -> Fe2O3 + ???

Can ions exist on their own ? ( In terms of stripping off or adding electrons to elements ) Will they combine with things in the air ?

which of these 2 is likely to produce a reaction? 1, Ammonium chloride + Nitric acid 2, Ammonium nitrate + Hydrochloric acid I predict number 1, but I`m uncertain at the moment (and will test it later).

differences in water qualities in different locations for example the great barrier reef and the central coast of NSW. they would probably have different amounts of trace elements, etc? This is in relation to using bought salt from Shops with trace elements etc (using money) or getting water from the local beaches around the central coast (free). this water is much cooler, i believe that any bacteria whether good or bad will probably die from the temperature change and the temperature will probably effect the concentration of trace elements etc in the water. Note: this tank is a great barrier reef style tank. So what is everyones opinion

Orbitals get "filled" with electrons starting from the orbital that has the lowest energy- 1s, than 2s<2p<3s<3p<4s<3d<4p<4d(?)... How does the "sequnce" qontinue?

can i form a mannich base out of phenylacetaldehyde , phenol and a seconday amine? if yes would the reaction take place at the ortho or para position of the phenol. and would the prodckt be a 1,2-diarylamine derivative? i have read that phenols form a mannich whit aldehydes and sec.amines. but i,,m not sure if a aromatic aldehyde like phenylacetaldehyde works too as a aldehyde. thank you kindly

Could someone tell me what would be the best way to separate these 3 solids. Potassium Nitrate, Sodium Chloride (Salt), and sand, all of which are in water. Any insight would be helpful thanks.

1, why most transitional metals are less reactive than metals?? 2, how compound ions are formed? eg, why sulfer + water = acid? Energy... why do you obtain energy when bonds are formed?? how does energy exist as such? Albert

a Thought just occured to me (from a Chemists standpoint). we know that Stars undergo Many atomic reactions, that convert hydrogen into helium and so on to even heavier elements such as Iron... we`re taught that an atom has a nucleus with electrons in "Orbit" around it , and that most of the size of an atom is empty space. now in a black hole, all this empty space is "taken away" and the electrons and protons and neutrons are all squished together by gravity into what`s called the singularity by. I`m wondering if at some point between being an element as we know it to being part of the singularity, that New elements are being produced, even for a fraction …

if two objects are placed together, then i assume that, due to the random breaking and reforming of the bonds of the chemicals of the two objects, that there would be a very few chemical links between the two objects. what i mean is, if plank A and plank B are placed together, then i assume that some of the molecules of plank A will dissasociate, some of the molecules of plank B will dissociate, and some molecules will form that reside half in plank A and half in plank B, thus chemically joining the two. my question is, if two objects are left touching for long enough, would they eventually fuse into one object? also, are their any restrictions on the type of …

My friend gave me a brief explanation on this topic, but I still don't fully grasp the concept. I understand that it has to do with electrons switching orbitals in order for an atom to bond with another, but beyond that, I do not understand... Can someone explain?

something has a half life of say... 15 minutes. Every 15 minutes, half of it decays. So, what happenes when there's only one molecule left, and 15 minutes passes? does it decay too? Or is this not how half-life works...

Alright, 2PbO2 -->2PbO + O2 15.000g of PbO2 makes 0.018mol of O2 What is the mass of the precipitate (PbO) What is the percent mass (of PbO)? Thanks

hello everybody.... i got a small problem in understanding the defference between these 2 terms( Precision and Accurancy), in terms of chemistry so, i will be greateful if someone can explain it to me.

What would happen if you kept electrolysing non-iodised salt solution, until all the Hydrogen and Chlorine present in it are exhausted ? (Apart from getting poisoned due to Chlorine ) Would the remaining Sodium react with the oxygen and form a considerable amount of Sodium Oxide ? Will this form on any of the electrodes or just collect at the bottom of the vessel ? What about other aqueous solutions of ionic salts ? Does it vary for each salt ?

Atom, molecule, proton, covalent bond, hydrogen bond or whatevers, those are confusing me. I thought atom equals to molecule, but apparently, it's not.

Hey, I have a problem i cant seem to get around, wondering if anyone out there is willing to help me out. FeSO4.7H2O + H2SO4 --> what? is it just FeSO4 + H2SO4 + 7H2O? and how do i solve FeSO4 + H2SO4 + KMNO4 --> ? any help would be appreciated - Leigh

I remember reading that there should theoretically be another region of stable elements beginning somewhere around 110~120. Is this true? If so, is it cyclic, with alternating regions of stable and unstable elements? Is there much chance that any of these multitudes of potential manufactured stable elements would actually be any use for anything?

About a week ago, I bought a UV torch ! I know I can use it for my TLC plates and it would also be nice for some of my lanthanidesalts. Europiumsalts should emit red light, terbiumsalts green, and lutetium blew ! But i'm still searching for other fun experiments with UV-light. Maybe you could help me

It's interesting. Go to the slide show and just skip through until it shows you the picture of the new periodic table (the other info in the slide show will be very mundane to you). http://www.slate.com/id/2122919?nav=wp

ok so i took an exam and got 0/8 for this one question. to be honest, im quite sure i got the correct answer, although it differs with the exam answer key in one place. so we start with 3 methyl 2 pentene. we add bromine and water in one step, then HCl. my first step showed the pi C=C bond attacking a bromine atom, resulting in the more substituted 3 carbocation and bromide anion. the p electrons in the oxygen atom of water then attack the carbocation from the opposite side that the bromine was added on, forming C-OH2 with a + charge on O. these first two steps are basically a concerted reaction, for all intents and purposes. the solvent then accepts…

our teacher tells us to just keep on adding coefficients and dividing or multiplying it by 2 until its balanced and it takes FOREVER to balance an equation.

What's the possible lowest pH of HF, given the highest concentration is 27M ( molarity)?

What do you know about Supramolecular Chemistry?

especially the thing when it refers to carbon all the time w./ the 1/12 amu thing. can anyone explain more thoroughly?
