My first guess is that CaCO3 --> Ca + CO3. However, after giving it some thought, I believe that CO3 may not be a product because it is unstable since it is a polyatomic ion. Would Ca + CO + O2 be a more reasonable guess, or is there anyone here who would like to give it a shot?
How about Calcium Oxide and Carbon Dioxide?
But isn't Calcium Carbonate pretty stable? eg Limestone? I thought you had to add an acid to break it up.
No guess from me. Calcium carbonate, isn't it? Anyway, it looks pretty stable.
If heated, it decompses into CaO (lime) and CO2. Lime is pretty much unstable: mixed with water it forms a mortar (NOT cement/concrete).
The mortar making process has been around a very long time.
Oh, that's right, Weirdo. I knew it and didn't think of it.
Ah yes. I think CaO + CO2 makes much more sense. Thanks.
CaCO3+2HCl=CaCl2+H2O+CO2
It is how they produce carbon dioxide in the laboratory.
I should know this I just learned about this in chemistry. I think that what you said is right and the equation is stable, because it has the same amount of ions on each side.
