c. AgNO3( s)
d. KNO3( s)

An answer would be really appreciated! Need it as soon as possible!

Respuesta :

Answer: a. [tex]Ag_2CrO_4( s)[/tex]

Explanation:

[tex]2AgNO_3(aq)+K_2CrO_4(aq)\rightarrow Ag_2CrO_4(s)+2KNO_3(aq)[/tex]

When silver nitrate [tex]AgNO_3[/tex] combines with potassium chromate [tex]K_2CrO_4(aq)[/tex] ,they undergo double displacement reaction in which exchange of ions take place.

The products formed are silver chromate [tex]Ag_2CrO_4[/tex] which is insoluble in water and thus formed as precipitate and potassium nitrate [tex]KNO_3(aq)[/tex]is soluble in water.

Answer:

The answer is A). Ag2CrO4(s)
