. Which of the following bases is the weakest? Explain your answer. (4 points) (CH3)2NH, Kb = 5.1 x 10-4
Clo", Kb = 2.9 x 10-7
SO42-, Kp = 8.3 * 10-13

08.01 hope this and can i get brainlist? ?

They both go downwards and the can break apart rocks 

  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
