Asked by Narasaq
I'm doing the single replacement reaction Mg +FeF3. Would it yield MgF3+Fe? What about the single replacement reaction Li+K2SO4? Would that yield LiSO4+K2? Thanks for checking.

You have to balance the charges of the ions in the compound.
Fluorine has a charge of -1, so when magnesium replaces the iron (III), the new compound is MgF2. Now all that is left to do is balance the reaction.
The sulfate group has a charge of -2, meaning lithium sulfate is Li2SO4. Potassium doesn't exist as a diatomic, so the actual reaction is:
Li + K2SO4 yields Li2SO4 + K
Also balance the above reaction.
Hope this helps.
