Question

The solutions of Pb(NO3)2(aq) and Na2S(aq) represented above are mixed, causing a precipitate to
To form.The Balanced equalion for the actions shown below
Pb(NO3)2 (aq) + Na2S(aq) Pbs(s) + 2 NaNO3(aq)
which of the following diagrams best represents the mixture after the reaction has proceeded as
Completely as possible?​

Answer 1

Answer:

C.

Explanation:

Hello there!

In this case, according to the given chemical reaction:

$Pb(NO_3)_2 (aq) + Na_2S(aq) \rightarrow PbS(s) + 2 NaNO_3(aq)$

We can see that at the end of the reaction solid PbS remain on the bottom of the beaker as it is a precipitate product whereas free sodium and nitrate ions remain in solution as sodium nitrate is an aqueous species. Therefore, the correct diagram would be C.
