The equation below describes a precipitation reaction:
MgO(aq) + CaCl₂(aq) -> MgCl₂(aq) + CaO(s)
Will this reaction actually happen as written?
a. No, because MgO is insoluble in water
b. No, because CaCl₂ is insoluble in water
c. No, because MgCl₂ is insoluble and will form the precipitate
d. No, because CaO is soluble and will not form a precipitate
e. Yes, the equation describes a valid precipitation reaction
