When a solution of AgNO3 is mixed with a solution of NaBr (pick all correct answers):

1) NaNO3 precipitate will spontaneously form.

2) After a few minutes pass, the concentration of Ag+ and Br- will be lower than when
the two solutions were first mixed.

3) After a few minutes pass, the concentration of Ag+ and Br- will be the same as when the two solutions were first mixed

4) The concentration of Ag+ and Br- are momentarily greater than in a saturated solution of AgBr.

5) AgBr precipitate will spontaneously form.
