Question

Fluorine gas is placed in contact with calcium metal at high temperatures to produce calcium fluoride powder. What is the formula equation for this reaction?

Answer 1

F₂(g) + Ca(s) → CaF₂(s)

Answer 2

Step-by-step explanation:

Fluorine exists as a diatomic gas and its chemical formula is
`F_(2)`. Whereas calcium exists in solid state and has a chemical formula Ca.

Therefore, when fluorine gas reacts with calcium metal then it results in the formation of compound calcium fluoride.

The chemical reaction will exist as follows.

`Ca(s) + F_(2)(g) \rightarrow CaF_(2)(s)`
