oh. and btw, is electrolysis a type of reaction?? is that called decomposition?? More over, how do you determine whether a salt is insoluble?? ie, the reaction is either solely neutralisation (acid + base + soluble salt) or neutralisation+percipitation(acid + base + insoluble salt)?? Albert

thanks woelen redox acid/base coordination precipitation are those all types of reaction?? what is coordination?? I thought all reactions are redox, because one reactant receives electrons and the other looses them??

thanks woelen, DQW said all reactions will occur above 0k. take, for example, water, and oxygen, do they react?? btw, woelen, can you be more specific at the potential energy?? in terms of chemistry?? not physics?? ie, e = mgh Secondly, Can I say acid generally have high thermodynamics?? Albert

Isn't CGI, equivalant to ASP, and pHp?? Albert

thanks, woelen. Your explanation,Straight to the point, Worths than a thousands books if I could read. [metaphor] Since it is too late at night, I will read it tommorow. Do you major Chemistry in university?? in US? in IVY LEAGUE? Go and entiltle yourself "Chemistry Expert" like JDurg. Albert

But CGI?? compiled program??? how's that possible?? CGI isn't compiled.

Why C/C++ is also faster when being executed by the server??? Since here it is just a matter of another script type, which is not machine code after compilation. Albert

So, how do you know what products are the reactants likely to form?? btw, what is "thermodynamics" in general? secondly, kinetics? does that mean both potential and kinetic energy? Albert

dave, which server support C/C++ "scripts"??

it is not much preferred to use pHp than html. html is a markup language used to make a hypertext content page. pHp is scripting language that works as a script on the server side to have interaction with the clients, for example, membership operation, search engine, etc, etc. I don't know much about perl, but I guess pHp is easier to work with. Whereas for perl, it is a programming language?? I am pretty sure, you are completely new to this. You didnot even intimate what is your aim for making your website. You assimilate pHp, html, and C. Practically, I never see people use C++ to make website, because it is a programming language, ie, you make programs, an individual sort of code runs by itself, not the script that run on the server.

Thanks So, overall, what determines whether the reaction will occur? ie, into a more stable form?? Albert

Are all reactions either endothermic or exothermic??

how about the pHp, and the database??

Any one??

What do you mean by "energy level"?? bond energy??

The furtherest my chem teacher has taught about reaction equation's system is about chantelier's principle. are all reaction equations revirsible?? btw, to YT, it does exist, it is a weak acid, when CO2 dissolves in water. My teacher has done a test. Just place your water, lid open in air. After a while, test the water's pH. But, of course, it depends on the conditions, for eg, temperature, any catalyst, pressure, etc. However, can all the factors of a reaction equation sum to one thing: Energy?? More pressure, more kinetic energy of particles, more temperautre, more heat energy?? Albert

why hydroxide react carbon dioxide in the first place? secondly, why water also react with carbon dioxide to form carbonic acid??

So exasperating, in my exam, I thought oxygen gas is a base for the reaction, of carbonic acid, I wrote H2CO3 + O2 ---> H2O + CO2 + O2 ,which sopposed to be simply without the oxygen Darn More over, I assimlated lime water as a indicator of oxygen, but actually it is for CO2. Any way, do you guys know why Lime Wire react with CO2?? Albert

Another two questions: will there be any reaction between lime water and oxygen?? if so, what? for carbonic acid, does it react with oxygen??

I just cant find, in chemistry, there is an unique method for testing water. For example, gas, hydrogen, we use to use pop test, which a splint would make a pop noise, and oxygen, in more abundant, will make the glow brighter. However, not only hydrogen will make that noise. I think any other gas fuel is apposite. ALbert

Hey, I do that as well, especially in winter. After all, I also put hand-lotion on to keep it nice and reduce the friction between my hands and the keys, since my hands are relatively small, ie, my biggest handspan is a perfect octave. Albert
