can someone explain to me this reaction and if there are anymore other reactions like this, and how to identify if the product will be something diffrient? does the product have to do with the fact that is is being burned and its not just yielding the product or what !?!?

Well this is not a typical acid-base reaction in aqueous solution.
This is cooking the hell out of the calcium carbonate. I guess it is more thermodynamically stable as calcium oxide. The carbonate moiety is not stable in that heat. An oxyen stays with the calcium and the carbon and oxygen reassemble as CO2 as they leave the compound.

Think you would get same pattern with other alkaline-earths/polyatomic ion compounds like BaCO3 or even alkali metals and transition metal compounds, although with different molar quantities like Li2(CO3). Sulfates, chlorates would probably do the same thing.

specific diatoms have siliceous skeletons. Forams have calcareous tests (shells). you're good on the subject of the diatoms even with the undeniable fact that. Upon dying their tests have been deposited on the sea floor. Diatomaceous earth is mined for many motives. One being an abrasive in toothpaste. that is extensively utilized in pesticides. that is a sturdy abrasive through fact that is largely sand or glass-like. below a microscope, diatomaceous earth sounds like broken glass. it is cool to verify. Like others have reported, calcium carbonate has many many makes use of. consistently the 1st factor that contains my ideas is antacids. My first hand adventure with calcium carbonate comes from coaching earth technological know-how. My pupils like to apply vinegar (acetic acid) to make limestone fizz. additionally they try this on some few million twelve months previous clam shells that I truthfully have. technological know-how is plenty relaxing. :)

Buring calciom carbonate or CaCO3 you need oxygen to burn it so thats why you get CO2 carbon dioxide as a resulting chemical as why the CaCO3 breaks down into CaO2
so the equation should look like
2CaCO3 + O2 ==> 2CaO2 + 2CO2

There are themddynamic considerations which make this reaction occur. The formation of a gas is favoured by entropy. Sometimes the heats of formation of products make the thermodyanics favourable
