Question

What would you expect to observe if hydrogen selenide were passed into PBNO3 solution?

Answer 1

electron transfer?

Answer 2

really?I hv no idea yo><

Answer 3

i'd expect a black lead(II)sulfide precipitate

Answer 4

is it NO2 gas?

Answer 5

\(H_2S + Pb(NO_3)_2 = PbS(s) + 2HNO_3\)

Answer 6

Opps sorry u cant observe a gas-.-

Answer 7

you can observe a gas :P its bubbles

Answer 8

Ohyah my bad><

Answer 9

@thomaster y didnt i think of that?

Answer 10

>< My brain..

Answer 11

I cant thank you enough!:D

Answer 12

I see i made a mistake i think...
\(H_2S + PbNO_3 = PbS(s) + H_2NO_3\)

Answer 13

u sure its not Pb(NO3)2?

Answer 14

But isnt it HSe or H2Se?

Answer 15

Yes that one!Sorry mines was wrong><

Answer 16

Its Pb(NO3)2 my bad

Answer 17

no selenium has 6 electrons and it needs 8 to compelte its outer shell so it needs to share 2 electrons. Hydrogen has only 1 electron to share so 2 hydrogen atoms share 1 electron with selenium
