Answer is:

A. Na₂S + FeBr₂ → 2NaBr + FeS.

B. MgSO₄ + CaCl₂ → MgCl₂ + CaSO₄.

E. AgNO₃ + NaCl → AgCl + NaNO₃.

Iron sulfide (FeS) has low solubility in water.

Calcium sulfate (CaSO₄) has low solubility in water and it will form white precipitate.

Silver chloride (AgCl) has low solubility in water and it will form white precipitate.

Gravitational force acts on two objects with which of the following?

ikadub [295]

The correct answer is A.

Gravitational force will attract any object with mass. It's why you're not floating in the air right now, but rather making contact with the ground. At the same time, since you have mass, you're also attracting other objects right now with gravitational force.
