you need to provide more details. you speak of a precipitate but you didnt mention the states of the H2O, CO2 and N2. if this was an aqueous solution, the H2O wouldn't be a reactant. is the H2O (l) or (g)? balancing the equation has nothing to do with the probability of a reaction. balancing is just writing the proportion of reactants and products out on paper. you really need to edit that post because i have no idea what youre talking about

today i got really bored while studying for the math regents. i decided that it's about time i made a bit of sodium citrate (Na3C3H5O7) and extracted it from solution. hey, who doesn't want an anti-clotting agent around the house? could save your life, ya know. well, i did the simple reaction and boiled off all the H2O. unfortuantely, i was left with a black solid stuck to my pan. that wasn't cool. i figured that i had burned my Na3C3H5O7. i found this solid to be useless so i added a small amount of H2O and found it to be extremely soluble. now i have a small bottle filled with a black solution. anybody know what that solute is?

meh, im not into making Pu. i have a friend who has a pot with a uranium paint; her father found this out when he went around the house with a geiger counter. im only interested in alpha emitters; my parents wont let me work with anything more dangerous. thanks anyway

bah. we didn't do anything cool in my chem class this year. for our last lab we used conc 12 molar HCl to see if it dispersed faster than NH3, but that's just about it...save that organic lab we did involving esterfication in which we used conc 18 molar H2SO4. we burned some Mg. no explosions whatsoever. no radioactive stuff whatsoever. unfortunately, i do not have access to a university lab. my former chem teacher probably wouldn't give me radioactive rare earth elements...or any type of cesium for fear i would blow it up. i really want to make one of these (with an alpha emitter). any other ideas and sources?

nothing means there is a severe lack of electrons. a coordinate covalent bond is formed when something donates both e- to the bond. actually, NH4OH boils at 36 celcius

even with americium 241? that's hardly dangerous to use, no?

bah. you dont see am241 often in nature

i still prefer a i oparin's theory

well.....it really isn't NaH2O+ or H2OCl- the same thing works for H3O+ in that it really isn't H3O+, rather it is H+ and H2O because there's nothing there to form a coordinate covalent bond. So, you actually have Na+, Cl- and 2H2O when you have NH3 dissolve in H2O, you get NH4OH when you have CaCO3 dissolve in H2O, you get Ca2+, CO32-, H2O, but it is a bit basic since you have Ca(OH)2 and H2CO3 formed in the process. the Ca(OH)2 is more basic than H2CO3 is acidic so the solution becomes basic. that is why you can use carbonates and bicarbonates for neutralizing bases

propylene glycol is CH3CHOHCH2OH it is an alcohol

yeah it didnt work

yeah but you cant use a subscript and a superscript and write above and below right? blahblah

not a chance in hell; we'll be $1.2 trillion in debt by then if bush stays in office. good thing he won't

yeah i can tell you actually: since i cant do superscripts and subscripts...i'll have to use the / 11/4Be->b- + 11/5B

what's sad is the definition of torture under us law. it says that something severe must be done for it to be defined as torture; something like causing perminant brain damage, death, the loss of limbs etc

eh, i can remember last year's regents. don't worry about it; all you need to do is read and make graphs...

oh, of course; but hey, that new element was in existence...even though it only existed for a fraction of a second. right, and so, since F is the most active possible nonmetal, the most active metal must be more active than F since mathematically, the most reactive metal has an infinately large atomic radius

the most reactive metal known to man is francium. the most reactive nonmetal known to man is fluorine. tell me if i'm wrong, but i believe that there are an unlimited number of elements since you could keep adding protons to a nucleus in one way or another. as a result, you could get an element with one valence electron that also has a greater atomic radius than francium, which would be more metallic than francium and thus would be more reactive than francium. i do not believe that there is a possible nonmetal that is more active than fluorine since fluorine has the smallest atomic radius for an element with an outermost orbital that is p and has 5 electrons. hydrogen would be more active than fluorine if it didn't have such a low ionization energy, but since it does, it tends not to form hydride ions.

perhaps you missed the above post; it's not AgCl; it's:

thank ye

does caffeine cause hunger? i've noticed that everytime i consume a great amount of caffeine that an almost insatiable hunger, even if i have just eaten a large meal. is it just me? is this a normal effect?

yeah, we are odd; that's universally known. i have nothing against the society of american silversmiths. in fact, i support their smithing of silver and such.

that is incredible. i wish i had friends who were that enthused by chem

eh i dunno it sounds awfully random. kinda like the brotherhood of american electricians

it's sad how there's a society of american silversmiths...
