Question

A reaction will occur when CaCl2 is combined with _______. A) F2 B) N2 C) Br2 D) I2

Answer 1

A reaction will occur when CaCl2 is combined with F2.

Step-by-step 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.
