Answer:
A reaction will occur when CaCl2 is combined with F2.
Explanation:
Let us know the terms at first.
Ca- Calcium
Cl2- Chloride, therefore CaCl2 is Ca+ Cl2 and that is calcium chloride.
Now, F2 is fluorine which is a yellow compressed gas.
When CaCl2 combines with F2, it gives out products like CaF2 or calcium fluoride, which is a white crystalline solid in powder form, and Cl or chlorine, which appears as a greenish-yellow compressed liquid gas with a pungent smell.
Here is the equation,
CaCl2+ F2= CaF2+ Cl.
