In which of the following is the name and formula paired correctly? A) ammonium sulfate, (NH4)2S
B) lithium carbonate, LiCO3
C) iron (III) phosphate, FePO4
D) magnesium dichromate, MgCrO4

C is the correct formula.

Iron, given the charge of 3, (III) combined with phosphate, which also has a charge of 3, causes them to cancel each other out, so there’s no charges that cross over. So the answer is C :)

Sorry if I didn’t explain this clear enough. If you need anymore help, feel free to ask

I’d have to say no because without oxygen in the water the fish would all be dead. so if you want to fish for dead fish, pick the ponds with the lowest oxygen concentrations.
