Автор ответа: KsenyaT

В лабораториях кислород получают термическим разложением некоторых оксидов и солей:

1) Из хлората калия (бертолетовой соли)

2KClO₃ = 2KCl + 3O₂

2) из перманганата калия (марганцовки в простонародьи ;) )

2KMnO₄ = K2MnO₄ + MnO2 + O₂

3) из нитратов щелочных металлов

2NaNO₃ = 2NaNO₂ + O₂

4) Из пероксида водорода

2Н₂О₂ = 2Н2О + О₂

5) Из оксида ртути

2НgO = 2Hg + O₂

И скорее всего все эти способы перспективны.
