Yeah I know the stuff takes lots of energy to refine...
Magnesium hydroxide is applied as a flocculant in water purification. Magnesium oxide reacts with acids. Magnesium is a silvery white metal. Magnesium and other alkali earth metals are responsible for water hardness.
Magnesium can react vigorously with steam giving an intense white light. Combine the zinc with hot water,and you get pure H2 for fuel cells,or it can be used in zinc air batteries.
Then they go on to provide random details about a variety of possible ways of using magnesium. Magnesium is highly reactive and stores a lot of energy.
General Delivery Conditions. Magnesium and Oxygen combine in a chemical reaction to form the Magnesium Oxide compound.
The substances initially involved in a reaction are called reactants or reagents.Corrosion Rate in Salt Water
There are a couple of YouTube video demos. It is a reflection on science journalism these days that we see articles like this. What I do like is reading about a new every few days.
In other compounds, for example asbestos, magnesium may be harmful. New University of Sydney research has revealed the ancient Cambodian city of Angkor underwent a gradual decline in occupation rather than an abrupt collapse.
Magnesium sulfate is a chemical compound containing magnesium, sulfur and oxygen, commonly called Epsom salt. Magnesium fires cannot be extinguished by water. This used to be phosphates, but it was discovered that these where hardly biodegradable, and caused eutrophication. Doesn't sound very promising.
Magnesium oxide is more normally made by heating magnesium carbonate. Read more.
