Question

Input the sum of the coefficient for the net ionic equation for strontium hydroxide reacting with sulfuric acid.   

Input the sum of the coefficient for the net ionic equation for calcium hydroxide reacting with hydrofluoric acid.   

Input the sum of the coefficient for the net ionic equation for potassium nitrate reacting with copper(II) chloride.

I need help understanding what compounds break up in the net ionic and which do not.

Answer 1

1) Input the sum of the coefficient for the net ionic equation for strontium hydroxide reacting with sulfuric acid.   

complete equation :

Sr(OH)2 + H2SO4 -----------------------------> SrSO4 + 2H2O

net ionic equation : 2OH- + 2H+ ---------------------> 2H2O

here it is acid base reaction . net ionic equation takes place between H+ and OH-

sum of coefficients : 2 + 2 + 2 = 6

2) Input the sum of the coefficient for the net ionic equation for calcium hydroxide reacting with hydrofluoric acid.

complete equation : Ca(OH)2 + 2HF ---------------------> CaF2 + 2H2O

net ionic : 2 OH- + 2HF -------------------> 2F- + 2H2O

sum of coefficients = 8

3) Input the sum of the coefficient for the net ionic equation for potassium nitrate reacting with copper(II) chloride.

2 KNO3 + CuCl2 ------------------------> Cu(NO3)2 + 2KCl

net ionic :

2K+ + 2NO3- + Cu+2 + 2Cl- -----------------> Cu+2 + 2NO3- + 2K+ + 2Cl-

sum of coefficents = 14
