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.

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

I'd try it, but I'm so ing sick of Chem after how bad it was last year, I just wanna forget about it (and I'm a lazy bam :p)
mdma: the formula for nitric acid that he had is correct, HNO3 |

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 |

| Turbonium |
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.:conf: |

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... |
