Abstract Although reversible covalent activation of molecular hydrogen (H 2) is a common reaction at transition metal centers, it has proven elusive in compounds of the lighter elements.We report that the compound (C 6 H 2 Me 3) 2 PH(C 6 F 4)BH(C 6 F 5) 2 (Me, methyl), which we derived through an unusual reaction involving dimesitylphosphine substitution at a para carbon of tris
Calcium - Simple English Wikipedia, the free encyclopedia
It reacts with water to produce hydrogen and calcium hydroxide.It reacts with water very fast when it is powdered. When it is in a chunk, it starts reacting slowly because calcium hydroxide makes a coating that does not dissolve on the calcium. If a little acid is added to calcium hydroxide, it dissolves it, making the calcium react very fast.
