what is produced when calcium reacts with fluorine in a synthesis reaction? ca + f₂ → \no caf\no caf₄\no 2caf\no caf₂
Answer
Explanation:
Step1: Determine ion charges
Calcium (Ca) is in Group 2, so it forms a $Ca^{2 + }$ ion. Fluorine (F) is in Group 17 and forms $F^{-}$ ions.
Step2: Balance charges
To balance the charges in the compound, we need 2 fluoride ions for every calcium ion.
Step3: Write chemical formula
The chemical formula of the compound formed is $CaF_{2}$.
Answer:
D. $CaF_{2}$
