Okay, Neither my instructor or the students, a small class mind you, cannot figure this equation out. It might not be able to be solved, but there might as well be one. Anyone want to give this a shot???

Equation:

Cu(s) + HNO3(aq) --> Cu(NO3)2(aq) + NO(g) + H2O(l)

Answer:

3Cu(s) + 8HNO3(aq) --> 3Cu(NO3)2(aq) + 2NO(g) + 4H2O(l)

* I don't know how to do subscripts here, but you get the point!


peace.

Steve

Copper + Nitric Acid = Coppor Nitrite + Nitric Oxide + Water

I think the formula for Nitric Acid is wrong, isn't it H2N03? I'm prolly wrong, i only got a C for A Level Chemistry

and if your teacher can't work it out, then you're definately screwed

I'd try it, but I'm so fucking sick of Chem after how bad it was last year, I just wanna forget about it (and I'm a lazy bam )

mdma: the formula for nitric acid that he had is correct, HNO3

Just when you thought this was over, it had only just begun...

I think it is H3NO2

Because Hydrogen has 2 postive ionen H2+ (spelled right) and those 2 go to NO3-..and the 3 goes to H2..

i remember thats how it worked..

so H3NO2

been sooo long since i had chmestry, kinda miss it

on it gimme a sec

is it acidic or basic solution?

nm acidic

can't you do some kind of trick where you add an OH and H2O to the formula to help balance it like this??

CU + 3HNO3 + H20 -------> CU(NO3)2 + NO + 2H20 + OH

although this is balanced...i don't think that's right (its been tooooo long hehehe), but don't you have to do something like that??

that's exactly what u do, assign oxidation numbers, etc.

I got an answer, but it's screwy, and I get this stuff right 99% of the time. r u sure u typed the eqn in right? double check it, i'll recheck mine again

Left Side:

CU = 1

H = 5

N = 3

O = 10

Right Side:

CU = 1

H = 5

N = 3

O = 10


i'm pretty sure that my equation is balanced, but that doesn't mean that i did it right hehehe...

Yeah, its typed in right, just I don't know if its possible. Trying to conclude whether or not it is.

I get the initial part correct, but restoring it to normal eqn yield incorrect result, weird...

3Cu + 8H(+) + 2NO3(-) ---> 3Cu(2+) + 2NO + 4H2O

full eqn (if I did it right, which according to this, I didn't):

3Cu + 2HNO3 + 6H(+) ---> 3Cu(NO3)2 + 2NO + 4H2O

THis is a stinker, and I don't know enough of chemistry to understand the oxidation method...
