b. K2CrO4( s)
c. AgNO3( s)
d. KNO3( s)

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

Answer 1

The answer is A). Ag2CrO4(s)

Answer 2

Answer: a.
`Ag_2CrO_4( s)`

Step-by-step explanation:

`2AgNO_3(aq)+K_2CrO_4(aq)\rightarrow Ag_2CrO_4(s)+2KNO_3(aq)`

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

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