        M(g) + IE à M(g)+ + e- IE = ionization energy

        X(g) + e- à X-(g) THE CHANGE IN ENERGY FOR  THIS                  IS  CALLED DE = Electron Affinity

GENERAL REACTIONS TO KNOW:

NaH(s) + H2O à H2 + Na+ + OH-

HCO3- + H+ à CO2 + H2O

CO32- + 2 H+ à CO2 + H2O

MCO3 à MO + CO2

 

BASIC ANHYDRIDE: MxOy

This tendency to act as a base especially in acidic solution is why we call many metallic oxides: basic anhydrides.

Generic:

MO + H-O-H à M+ + 2OH-

Examples:

BaO + H2O à Ba+2 +2OH-

Na2O + H2O à 2Na+ +2OH-

MgO + H2O à Mg+2 +2OH-
