Question

I don't understand this question... Plz help

Answer 1

you need to solve the reactions then you need to look on a solubility chart to see if the products of the reactions are soluble or insoluble or one one is soluble and the other is not

Answer 3

ok,

for NH4Cl + Pb(NO3)2

You can look charges up but these are the ions:
NH4 has a charge of +1
Cl has a charge of -1
Pb +2
NO3 -1 charge
Pb +2 charge

Assuming double displacement and also assuming that electromotive force isnt a thing in this question (these reactions are spontaneous)

NH4Cl + Pb(NO3)2 -> NH4NO3 + PbCl2

Look at the ions formed


NH4 +
NO3 -
Pb +2
Cl -

Check your rules or the solubility table

Answer 4

I still don't get it. :| The answers are in the image. I'll ask my instructor to explain it to me later. Thanks for trying to help me (both of you). I appreciate it. :)
