Answer: a) 3
On the right side of the equation you have 6F, so you need 3 copies of F2 to balance the equation.
Answer:
a) 3
Explanation:
The unbalanced combustion reaction is shown below as:-
[tex]N_2+F_2\rightarrow 2NF_3[/tex]
On the left hand side,
There are 2 nitrogen atoms and 2 fluorine atoms
On the right hand side,
There are 2 nitrogen atoms and 6 fluorine atoms
Nitrogen atoms are balanced and only fluorine atoms have to be balanced by applying a stoichiometric coefficient of 3 in from of [tex]F_2[/tex] in the reactant side.
Thus, the balanced reaction is:-
[tex]N_2+3F_2\rightarrow 2NF_3[/tex]
Coefficient in front of the [tex]F_2[/tex] in the balanced equation - 3
