Re: The Imsides method
Tilly ; Calcium hydride is not the same thing as calcium oxide or calcium hydroxide or calcium dihydroxide. Calcium hydride is one calcium atom bonded to two hydrogen atoms. The formula would be Calcium (1) Hydrogen (2) or CaH2. I expect it is made by heating pure calcium metal with hydrogen gas molecules under high pressure. A more common example of a hydride is Lithium Aluminum Hydride. It is used to hydrogenate (add hydrogen to) some organic molecules . I think the formula is LiAlH4, Lithium (1 atom) Aluminum (1 atom) Hydrogen (4 atoms) That's one atom of lithium , one atom aluminum and four atoms of hydrogen all bonded together in one molecule.
