Barium - Simple English Wikipedia, the free encyclopedia
Barium is reactive, and if you put pure barium metal in the air, it will react with oxygen. At first it will turn black, then white as barium oxide is formed. Barium reacts with water to make barium hydroxide and hydrogen gas. Barium also reacts very fast with acids
Aluminium reacts with steam a protective oxide is produced
Like the reaction between magnesium and water, it is possible to react aluminium with steam. However, the aluminium oxide produced forms a barrier on the surface of the aluminium which prevents further reaction. When aluminium reacts with steam, the
Calcium phosphide - Wikipedia
Calcium phosphide (CP) is the inorganic compound with the formula Ca3P2. It is one of several phosphides of calcium, being described as the salt-like material composed of Ca2+ and P3−. Other, more exotic calcium phosphides have the formula CaP, CaP3, Ca2P2, and Ca5P8. Ca3P2 has the appearance of red-brown crystalline powder or grey lumps
