Subsequently, one may also ask, what gas is produced when magnesium and sulfuric acid react?
hydrogen gas
In this way, what happens when magnesium and oxygen react?
When the magnesium metal burns itreactswith oxygen found in the air to formMagnesium Oxide.Magnesium gives up two electrons tooxygen atoms toform this powdery product. This is anexothermicreaction.
Magnesium occurs naturally only incombinationwith other elements, where it invariably has a +2oxidation state.The free element (metal) can be producedartificially, and ishighly reactive (though in theatmosphere, it is soon coatedin a thin layer of oxide that partlyinhibits reactivity– see passivation).
