Question

If you rewrite the following word equation as a balanced chemical equation, what will the coefficient and symbol for fluorine be?
nitrogen trifluoride → nitrogen + fluorine

a) 3F2

b) 6F2

c) F3

d) 6F

Answer 1

The given word equation is:

Nitrogen trifluoride-->Nitrogen + Fluorine

The chemical formula of nitrogen trifluoride is $NF_{3}$ and that of nitrogen gas is $N_{2}$and fluorine gas is $F_{2}$.

The balanced chemical equation representing the decomposition reaction of nitrogen trifluoride to nitrogen and fluorine will be,

$2NF_{3}-->N_{2}+3F_{2}$

The chemical formula of fluorine gas will be $F_{2}$ as fluorine exists as a diatomic gas in it's pure state. The coefficient of fluorine will be 3

Therefore, the correct answer is a) 3F2

Answer 2

The correct answer is 3f2
