Question

100 g amestec echimasic din substantele ,,i ,, si ,,h,,contine; 2,3902g H,48,6301gCl, 16,3265gS. C care sunt substantele ,,i,, si ,,h,,

Answer 1

H : 2,3902%      Cl : 48,6301%       S : 16,3265%    O : 32,6532%  
   m1 = m2 = 50g
daca i = HCl      nHCl = 50/36,5 = 1,369863 moli   m1H = 1,3968g
⇒⇒⇒  h = HaSbOc     n h = 50/(a+ 32b + 16c)
mH = 1,0203g         | : 1 = 1,0203        |: 0,5102 = 2 
mS = 16,3265g      | :32 = 0,5102       | : 0,5102 = 1
mO = 32,6532g      | : 16 = 2,0408       | : 0,5102 = 4      h = H2SO4
