1. A and B react to form AB, but what forces bind A and B together in AB ??

2. The ratio of reactants used to make AB is 1:2 - 1 part A, 2 parts B
    What's the scientific explanation for this ratio?  Will other ratios work equally well?
      »ò
    Is "one part A, two parts B" a must for making AB, or will other ratios work just as well?

3. Missing from the discussion is how pH values affects e absorption
      »ò  " ... how absorption is affected by pH
