* Potassium chlorate (KClO3): This is a common laboratory reagent that decomposes upon heating to produce potassium chloride (KCl) and oxygen gas.
* Potassium permanganate (KMnO4): This compound also releases oxygen when heated, along with manganese dioxide (MnO2) and potassium oxide (K2O).
* Hydrogen peroxide (H2O2): This compound decomposes into water (H2O) and oxygen gas when heated or exposed to a catalyst.
* Sodium chlorate (NaClO3): Similar to potassium chlorate, this compound decomposes into sodium chloride (NaCl) and oxygen gas.
* Metal oxides: Many metal oxides, such as mercury oxide (HgO) and silver oxide (Ag2O), decompose upon heating to release oxygen and the corresponding metal.
It's important to note that heating any substance can be dangerous and should only be done in a controlled environment with proper safety precautions.
