Same: both decomposition reactions
Different: different devices, whether to add catalyst...

Hydrogen peroxide is used in the laboratory to produce oxygen, because (),(), so the selected generation device is (); and potassium chlorate or potassium permanganate is used to produce oxygen Because (),(), the selected generating device is (). Urgent! The laboratory uses hydrogen peroxide to produce oxygen, because (),(), so the selected generation device is (); but uses potassium chlorate or potassium permanganate to produce oxygen Because (),(), the selected generating device is (). Urgent!

The laboratory uses hydrogen peroxide to produce oxygen, because (hydrogen peroxide is liquid),(reaction does not need to heat), so the selected generating device is (solid-liquid normal temperature type without alcohol lamp); while uses potassium chlorate or potassium permanganate to produce oxygen, because (because the reactant is solid),(needs to heat), so the selected generating device is (solid-solid heating type with alcohol lamp).
