what is produced when calcium reacts with fluorine in a synthesis reaction? ca + f₂ → \n○ caf\n○ caf₄\n○ 2caf\n○ 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 a $F^{-}$ ion.
Step2: Balance charges
To balance the charges in an ionic compound, we need 2 fluoride ions ($F^{-}$) for every calcium ion ($Ca^{2+}$).
Step3: Write the product
The chemical formula of the product is $CaF_{2}$.
Answer:
D. $CaF_{2}$
