Hydrogen sulfide lead nitrate ---> lead sulfide ...?

Question

I'm having slight trouble finishing off this equation:

H₂S Pb(NO₃)₂ ---> PbS ........

Is this one of the 6 (I think) reaction types?

Any assistance is appreciated.

Answer 1

H2S + Pb(NO3)2 → PbS + 2HNO3

By the way, how do you get the subscript? I can't get it.

Answer 2

No problem...H2S + Pb(NO3)2 -----   2 HNO3 + PbS (s)

it is a precipitation reaction in that PbS is a black insoluble compound Ksp ~ 10^-28
