With which of the following ions would you expect a precipate to form after the addition of silver nitrate solution? select all that apply.

nitrate
carbonate
sulfite
sulfate
phosphate
chromate

The following ions : carbonate, sulfite, may be sulfate and phosphate  are capable of forming precipitate by exposing them to a solution of silver nitrate.

Explanation:

There are some  solubility rules you should know.

Silver nitrate is a salt that DOES NOT form a precipitate.

AgNO3  >  Ag+  +  NO3-  

2Ag+  +  CO3-2  <>  Ag2CO3

2Ag+  +  SO3-2 <> Ag2SO3

2Ag+  +  SO4-2 <> Ag2SO4

3Ag+   +  PO4-3  <> Ag3PO4

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.

i think it's letter a.
