Question

What is produced when calcium reacts with fluorine in a synthesis reaction?
Ca + F2

Answer 1

calcium fluoride or CaF2 is produced.

Step-by-step explanation:

When calcium reacts with fluorine in a synthesis reaction you would get CaF2

Answer 2

`CaF_(2)` is formed here.

Step-by-step explanation:

`F_(2)` is an oxidizing agent and Ca is a reducing agent because F atom is highly electronegative and Ca atom is highly electropositive.

Therefore Ca is oxidized to
`Ca^(2+)` ion by giving electrons to
`F_(2)` and reduces
`F_(2)` to
`F^(-)` ion.

Therefore an insoluble ionic compound
`CaF_(2)` is formed as a result.

Balanced equation:
`Ca+F_(2)\rightarrow CaF_(2)`
