Answer:
more/less depending on if it lost or gained electrons during the ionic bond process
The reaction is a hydrogenation reaction of an alkene, and its equation is:
C₂H₄(g) + H₂(g) → C₂H₆(g)
Therefore, this reaction can be sped up just as any other irreversible reaction may have its rate increased, by increasing temperature and pressure to increase the effective collisions of molecules.

reaction is a type of nuclear reaction where two or more nuclei combine or
collide to form an element with a higher atomic number. This happens when the
collision is in a very high speed. In this process, some of the matter of the
fusing nuclei is converted to energy.</span>
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.
