Which of the substances below would dissociate into ions when dissolved in water? Select all that apply. A. AgCl
B. NaBr
C. Pb(OH)2
D. KOH

B. NaBr

D. KOH

Explanation:

Below is the solubility rules given for you knowledge.

Salts of

Group 1 elements are soluble()Ammonium ion is soluble ()The nitrate are generally soluble( of Cl- , Br- , and I- are soluble, except Ag+ , Pb+2, and (Hg2)+2most sulfate are soluble, except Ba+2, Ca+2,Pb+2, Ag+, Sr+2.most hydroxide salts are only slightly soluble, except NH+4, Li+, Na+, K+Most carbonates are insoluble (CO3 2-) Except group 1 and NH+4most phosphate are insoluble except group 1 and NH+4  

so using the rules above

NaBr , KOH are soluble, Pb(OH)2 is slightly soluble and AgCl is not soluble.

Although the diagram is not shown, i know that the convection is heated by a the core.

It has to be b i hope this
