1) Supply the IUPAC systematic name for each of the following ternary oxyacids.
(a) HClO2(aq)
(b) H3PO4(aq)

2)Supply the IUPAC systematic name for each of the following
ternary oxyacids.
(a) HC1O4(aq)
(b) H2SO3(aq)

Ithink the answer is b.

The mole ratio of hydrogen to ammonia is 3: 2.

  the volume of  0.220 m k2s    solution  required  to  completely  react with 175 ml  of 0.115m co(no3)2  calculate the moles  of co(no3)2 =  molarity x volume/1000175 x0.115/1000= 0.02  moleswrite  the reacting  equationk2s(aq)  +  co(no3)2  = 2 kno3(aq)  + cos(s)by  use  of mole ratio between k2s to co(no3)2 which  is  1: 1 the moles of k2s is therefore = 175  x0.115/1000= 0.02  molesvolume = moles/molarity=0.02/0.22=0.09  ml  of k2s
