Chemistry

Ex: CH4 + 2 O2 ----> CO2 + 2 H2O + 802.5KJ Also, where can we find a list of reactions with their catalyst? Thank you.

If so, why?

I know there're two ways in which catalyst works--adsorption and by forming intermediate compounds. Simply, a catalyst stick to the surface of the reactant and increases their chances of collide with each other. That increases the reaction rate because the speed in which a reaction occurs is depends upon the rate in which the molecules collide. Is it because of their electron configuration that they don't react(catalyst)?

I came across an article on Polarized Hydrogen on the internet but only one. I am curious if any one has any more information on it. What I read was that at very cold temperatures Hydrogen will spin at high rates polorize itself and emit energy. Does anyone know of any more studies concerning it or is it false.

Has anyone else noticed the "theoretical gap" between organic and inorganic chemistry? For example, the geometries of main group, and organic compounds can be approximated with the VSEPR theory. However, this breaks down in the d-block. d-block coordination chemistry requires the use of the Kepert model, Ligand Field Theory, or Crystal Field Theory [Equivalent to MO theory in the main group]. I'm quite familiar with all of this stuff, but it has always bothered me that there is not at least some "pseudo-unified" model of chemical bonding. I understand why none of these theories could work for all compounds, but I guess I just really wish they did. You guys should c…

This question came into my mind while I was studying chem. It would be helpful if anyone know. Thank you:-)

I've got a friend who has a sonicator/de-gasser, whatever you want to call it in his house. He told me that he would like to see what would happen if he sonicated an un-opened bottle of champagne; I need to know if that would be dangerous? I mean it would obviously make a huge mess, but would there be any actual danger in doing that?

HI I was wondering if i let milk spoil for a while and then filtered the curds out and distilled the liquid would that give me a clean solution of lactic acid.

Anyone know the composition of Martial Soil? I am aware that Fe203 is in abundance or am I wrong?

Hello, just wondering about ionic compounds and why they come together to form crystalline lattice structures (when they are solid.) It seems to me that in order to form a crystalline lattice structure, each molecule (or formula unit) needs to be attracted to each other. And since NaCl, for example, is supposed to have a neutral charge, one molecule of NaCl should not be attracted to another NaCl molecule (or anything else for that matter.) I can understand covalently bonded compounds being attracted to one another and clumping together, since they share electrons and will be slightly polar due to the sharing. But ionic compounds do not share electrons they tra…

Hi, As a layman curious about industrial manufacturing processes, could you recommend some books? Specifically, I am looking for a reference book that I can just pop open at a given page if I am curious about a certain element. I am not looking for a general interest book that deals with elements or molecules in terms of their socio-economic, historical roles as well as their scientific properties (a book of this sort would be "Salt" by Mark Kurlansky or "The Invention of Air" by Steven Johnson). Such a book would be an encyclopedia of elements that discusses among other things (1) chemical properties (2) uses in modern products (e.g. tellurium as it's…

Is there a way to tell if a reaction will be ectothermic or endothermic just by looking at the chemical equation? Thanks

well im looking for a Geiger counter. i want one that can do alpha, beta and gamma im looking in the $10-$150 range any help would be great

can i make sodium percarbonate with just 3% H2O2. thanks

what hydrocarbon has the highest flash-point? after doing google searches empty handed or conflicting answers i turn to you. i would like the flash point to be 400f or higher thanks oh and im specifically talking about oils and waxes

I would like to make some gluconate salts for samples but i need some gluconic acid. I would appreciate it if you guys could please tell me how to make some. Thanks. Merged post follows: Consecutive posts mergedIt would be nice if someone could answer my question.

Atoms are made up of protons and neutrons, which are made up of quarks. What are quarks made up of?

Hi, I'm working on a science fair project on Alzheimer's and it's basically all about the protein Tau being hyperphosphorylated... I know in this particular case, that phosphorylation is used to activate this protein (tau), and that kinases and phosphatases that add and take awat those phosphates. Now my question : How come phosphorylation activates proteins? Does phosphorylation have another purpose? What else is important to know about phosphorylation?

For our lab project we are doing a project where we are analyzing antioxidants. The only requirement is that it be something with food, and that we have an actual hypothesis (i.e. don't just make your experiment "I wonder how many antioxidants are in blueberries"). I'm trying to be creative. Obviously we could research amounts/strength of antioxidants in different types of fruit, or the effect of cold or age etc., but I want to be more original. The only thing is, we have to propose why we think something will happen, not just collect data. So, for example, we are kind of limited because lets say I want to analyze data about antioxidants in different par…

I'm wondering if there is any way to purify (remove stabilizers/impuritys) Hydrogen peroxide. I've searched the forums and only seen people trying to concentrate H202, not interested in concentrating it just purifying it. I use peroxide for various things including as a mouth wash after i brush my teeth, my concerns are it says on the bottle along with using it as a mouth wash not to use it for longer then a week. I'm assuming because of the stabilizers, I got food grade peroxide thinking it would have been without stabilizers but have found out it still contains them, is there anyway to remove these stabilizers so I can safely use H202 long term without any adverse ef…

Hi: If all other factors are constant, does a lower pH indicate more entropy than a higher pH? I ask because chemical reactions that lead to a decrease in order, often increase the acidity of the environment. For example, our consumption of fuel increases the amount of CO2 in the atmosphere. This CO2 dissolves in the ocean causing a decrease in the sea's pH. Thanks, Green Xenon

What does a metal vapor look like? Sodium vapor, for example? I'd imagine it would lose it's silvery aspect, but would it have a color?

I have a bottle of lotion on my nightstand (don't ask) along with some pennies. Occasionally, some of the lotion spills on the pennies, and the lotion turns green. I assume some chemical in the lotion is reacting with the copper plating in the pennies, due to the characteristic color, but I'm curious as to exactly which reaction is taking place. Below are the ingredients to the lotion I have: INGREDIENTS: Water, Petroleum, Glycerin, Stearic Acid, Glycol Stearate, Dimethicone, Colloidal Oatmeal, Cetyl Alcohol, Glyceryl Stearate, Magnesium Aluminum Silicate, Carbomer, Stearamide AMP, Ethylene Brassylate, Triethanolamine, Disodium EDTA, DMDM Hydantoin, Iodopropynyl Butyl…

Are there any colored gases besides the halogens and NO2? Any that are non-toxic?

Hey guys. New to this forum...first post. I have looked endlessly to try and find out how to make this material but apparently no one knows how...or has no reason to try. Ill keep it pretty simple. Im trying to accomplish what this guy did in this video. Basically needs to be an opaque gel like material that when you run something across it or put something ontop of it it move away...and then it moves back. http://inventorspot.com/articles/delightable_excites_and_delights_8050 I've experimented with some ridiculous househould chemicals with lackluster results. Either it's too thick and won't return back or it's too watery and looks like crap. Any ideas?
