As you add more acid to the solution the amount of dissociation increases to compensate for it. But since the acid is weak, it will never have more ions dissociate than are in the concentrated solution being added. % ionization is the concentration of dissociated H+ ions divided by the initial concentration of the weak acid. 

% ionization = [H+] / [weak acid] x 100% 

As you increase the concentration of the weak acid, the numerator increases more than the denominator so the percentage goes down.

What is the product when magnesium reacts with nitrogen? Mg(s) + N2(g) → Mg2N3(s) Mg3N(s) Mg3N2(s) MgN3(s)
bixtya [17]
Look at the periodic table to find the charge on atoms.
 Magnesium is +2 and Nitrogen is -3. Since there are two nitrogen charge 2*-3 = -6 there needs to be 3 Mg then (3*2+ = 6+) to pair with the two nitrogen.
3 Mg(+2) + 2 N(-3) = Mg3N2
