Zad.1

a. SO2

mSO2 = 32u + 2*16u = 64u

b. HCl to kwas beztlenowy

c. CO2

mCO2 = 12u + 2*16u = 44u

d. N2O5

mN2O5 = 2*14u + 5*16u = 108u

e. P4O10

mP4O10 = 4*31u + 10*16u = 284u

Zad.2

H2 + S = H2S gaz  siarkowodór

H2S gaz=[H2O]= H2Saq   kwas siarkowodorowy

Zad.3

a. H3PO4 =[H2O]=  H+ + H2PO4-

   H2PO4- =[H2O]= H+ + HPO4 2-

   HPO4 2- =[H2O]= H+ + PO4 3-

.....................................................................

   H3PO4 =[H2O]= 3H+  + PO4 3-

b. HNO3 =[H2O]= H+ + NO3-

c. HCl =[H2O]= H+ + Cl-

d. H2CO3 =[H2O]= H+ + HCO3-

    HCO3-  =[H2O]= H+ + CO3 2-
