[¸Ðл½±ÉÍ - Á¦Ç󵨵À] 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 |
