Hey,
Our class was doing the unknown carbonate/bicarbonate lab. Here was the question:
It is possible to cause a carbonate to decompose if heated to a high enough temperature. Write an equation that describes what happens when sodium or potassium carbonate decomposes upon strong heating.
I thought it would be K2CO3 ===> K2O + CO2

Yes I understand what some of you may think...I know how the bicarbonate reaction works, but the question is "Further Application" to it...A possible hypothesis is that we didn't get as much salt as we were supposed to because it was overheated...and the teacher wants the decomposition reaction for that.

It is K2CO3 -------> K2O + CO2

sodium or potassium carbonate when heated will not undergo decomposition. It is sodium or potassium bicarbonate undergo decomposition.
2NaHCO3 + heat -> Na2CO3 + CO2 + H2O
