Balance the following chemical reaction and tell what type it is. Explain why you chose that type of reaction in your answer.
AlPO4 + CaF2 → AlF3 + Ca3(PO4)2

the answer would be c

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.

you need to have a picture of the atom that way we can answer it
