balancing an equation

[mollykins]

in chemistry today, we had a substitute and none had a clue how to do the work.

there were a set of questions, including, write a balanced word and symvol equation for the reaction between nitric acid and water.

nitric acid + water = what, we've only done acids and metals and not been taught what the products of a acid and water are. We all thought that it was just a more dilute version. In which case, would it be
H(little 3) NO(little 4), and is this whst you do to all chemicals to show they're more dilute or would you just say 1/2hcl or soemthing?

Does this help?

Well its a heck of a long time that I did this stuff, but as far as I'm concerned nitric acid and water gives just dilute nitric acid, it doesn't change into anything else.
Are you sure the question wasn't intended to be based around nitric OXIDE plus water?
That reacts (with oxygen in the water as well to produce nitrous acid HNO2.
Something like 4NO+O2+2H2O = 4HNO2

I've jsut looked on the sheet, and it was nitric ect acid with water, the science teacher expected us to know how to do the symbol equation indicating a dilution because aparantly it was in the texbook, but it wasn't.

ahh, before vic, i couldn't connect to your link, i think that's what he was after.
