Answer

Explanation:

Step1: Identify reactants and products

Fluorine gas ($F_2$) and calcium metal ($Ca$) are reactants, calcium fluoride ($CaF_2$) is product.

Step2: Determine states of matter

Fluorine is gas (g), calcium is solid (s), and calcium - fluoride powder is solid (s). High - temperature reaction is indicated by $\triangle$ above the arrow.

Step3: Write correct chemical formula

Calcium has a + 2 charge ($Ca^{2 + }$) and fluorine has a - 1 charge ($F^-$), so the formula of calcium fluoride is $CaF_2$.

Answer:

D. $F_2(g)+Ca(s)\xrightarrow{\triangle}CaF_2(s)$
