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?

Explanation:

Fluorine exists as a diatomic gas and its chemical formula is . 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.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

if you mean hydrogen and oxygen then water is the product
