Calculate whether or not a precipitate will form if 2.00 mL of 0.60 M NH3 is added to 1.0 L of 1.0 × 10−3 M FeSO4. I want the final number too

The answer to this is the 3rd choice!

The net force is 100

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.
