Alright, so we want to write a balanced equation from the word equation.
00:04
So we have iron 2 -carbonate, which is feco3, and it's reacting with nitric acid, which is hno3.
00:17
So basically you can think of this, you know, since acid's ionized, this is basically like two ionic compounds, and then you'd have a double replacement reaction.
00:25
So you can just interchange either the positive charges or the negative charges.
00:29
I'll do the positive charges since they're first.
00:31
So h then goes with co3, and fe with no3.
00:35
So if we have h +, and co3 2-, that makes h2co3, two of the positive charges to balance out, so you have the same amount of pluses and minuses, so you get carbonic acid.
00:51
And carbonic acid is notoriously known for, like when you see this as a product, it's not stable, it likes to decompose, so we would expect it to form h2o plus co2...
