$\frac{1}{2} N_{2} (g) + \frac{3}{2} F_{2} (g) \to N F_{3} (g)$ $1/2N_2(g) + 3/2F_2(g) rarr NF_3(g)$

Explanation:

$N F_{3}$ $NF_3$ is in fact not so nasty .... it is much safer than $N C l_{3}$ $NCl_3$ or $N I_{3}$ $NI_3$ .. Of course the direct synthesis with fluorine gas is the province of specialist inorganic chemists...

$N_{2} + 3 F_{2} \to 2 N F_{3}$ $N_2 +3 F_2 -> 2NF_3$

Explanation:

Nitrogen molecule is $N_{2}$ $N_2$

Flourine molecule is $F_{2}$ $F_2$

Nitrogen triflouride is $N F_{3}$ $NF_3$
(tri- means 3, and $N$ $N$ usually has 3 covalent bonds, $F$ $F$ has 1,
so 3 $F$ $F$ to 1 $N$ $N$ )

write unbalanced eqn for reaction

$N_{2} + F_{2} \to N F_{3}$ $N_2 + F_2 -> NF_3$ (not balanced)

now balance the number of atoms on each side:
at least 2 atoms of nitrogen so at least 2 molecules of $N F_{3}$ $NF_3$
2 molecules of $N F_{3}$ $NF_3$ need 6 $F$ $F$ atoms = 3 $F_{2}$ $F_2$ molecules.

$N_{2} + 3 F_{2} \to 2 N F_{3}$ $N_2 +3 F_2 -> 2NF_3$ (now balanced, 2 $N$ $N$ and 6 $F$ $F$ atoms each side)
