Many metals react with oxygen to form metal oxides. Potassium and sodium are soft metal which are easily cut exposing a shiny surface which changes to dull rapidly. The change from shiny to dull ...
When metals react with oxygen, metal oxides are formed. The speed of the reaction depends on the reactivity of the metal. Watch this video for a practical demonstration of reacting metals with oyxgen.
The structure of the trifunctional clavaminic acid synthase exhibits an emerging structural motif found among nonheme iron oxygen activating enzymes that provides the metal active site the ...
