Don't post when you know little about a subject matter. I may have been a bit rude, but that does not change the fact that you were wrong, and that you admitted to being "behind" in class, showing you had little knowledge of the subject matter. In order to avoid a flame war, everyone just stick to the chemistry.[/quote]
the "i'm surprised i know this were wayyyyyyyyy behind in this part in chemistry" was before i knew i was wrong.
ALSO when you don't know something you tell the teacher in order to learn. i doubt i was going to get corrected if i hadn't posted something. and by being corrected i have just learned something to use in future chemistry class.
and if you didn't want to start a flame war you shouldntave been so rude

Combustion:
Ax+O2--->CO2+H20[/quote]

[quote=darksuitguy]...you just showed how little you know. Combustion rxns only produce CO2 and H2O. Nothing more, nothing less.
EDIT: Heat/energy is also produced, but that's learned later during the free energy unit.[/quote]
No need to be offensive seriously.
i just assumed since he didn't say they ONLY produce CO2 and H2O (hey said some type of oxide [nitrogen dioxide] and water [H2O])
so i not having been taught this assumed "oh it is a combustion reaction because it follows the guidelines he said"
Next time you could just correct me instead of saying you just showed how little you know

[quote=dracox5234]you just answered your own question buddy

Cu + 4HNO3 -> Cu(NO3)2 + 2NO2 + 2H2O
2NO2 = Nitrogen Dioxide
2H20 = Water

this is a combustion reaction

[quote=carnagechaos]Well, I don't have my notes with me but if I'm remembering right, doesn't combustion yield an oxide + water all the time?[/quote]

Redox.
or something like that.

In a combustion reaction, a compound is usually burned with O2 to make CO2 and H2O only. Since NO3=>NO2, it's probably redox.

My best guess would be a single displacement reaction.

Not a double displacement because.. well, I don't have to get in depth...
Not a neutralization reaction because there isn't a base in the reactants.
Not combustion because there isn't oxygen in reactants, nor is there an oxide or water in the products.

We're learning about those this week but just got done the nomenclature test today. All I can currently do is name the chemicals, but yeah, it's
Copper(I) + 4 nitric acid -> Copper(II) (Nitrate)2 + 2(Nitrite) + dihydrate...And from what we learned of salts is a hydrated salt(reason for the dihydrate) is formed when an ionic compound absorbs H2O into a solid structure. So hmm, I don't think I helped at all.

Im also pretty sure it has to have carbon dioxide to be a combustion reaction.

Nitric Acid and Copper reaction.

edit:

It's single replacement.

My chem is a bit rusty.

[quote=RoyalxNub]How would this be either?
I mean I know I'm rusty in chemistry but single displacement is just moving one thing.

While a combustion reaction always has heat as a product so..
idk.[/quote]
