I'll show you the steps and hopefully you learn from it!

1) First we do double displacement reaction

K2CrO4 + AgNO3 ---> KNO3 + Ag2CrO4

Then we look for compound that remains a solid. Theres usually a chart for this, Ag2CrO4 is insoluable so it doesnt dissociates

Now we split every single compound to its basic components except for Ag2CrO4

2K + CrO4^-2 + Ag + NO3 ---> K + NO3 + Ag2CrO4

Now we match and cancel

CrO4^-2 + Ag ----> Ag2CrO4

I hope you understand :)

a)
CrO4{2-} + Ag{+} → Ag2CrO4

b)
CrO4{2-} + Pb{2+} → PbCrO4

c)
CrO4{2-} + Hg(2+} → HgCrO4

d)
Ag(+) + Cl{-} → AgCl

e)
Pb{2+} + Cl{-} → PbCl2

f)
Hg(+) + Cl{-} → HgCl

g)
Ag{+} + 2 NH3 → [Ag(NH3)2]{+}
