Answer:
2NF3------->N2 +3F2
Explanation:
For the equation to be balanced, there must be six fluorine atoms on both left and right hand sides of the chemical reaction equation. Hence the coefficient of chlorine on the right hand side must be three for the equation to be balanced.
complete 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
Choices are:
a) 3F2
b) 6F2
c) F3
d) 6F
Answer:
a) 3F2
Explanation:
According to the word equation, the reaction is the decomposition of nitrogen trifluoride to nitrogen and fluorine.
nitrogen trifluoride → NF3. The tri indicates their is 3 atoms of fluorine atoms.
The chemical equation can be represented as follows :
NF3 → N2 + F2.
To balance the equation the number of atom of element on both sides of the equation should be same.
NF3 → N2 + F2.
2NF3 → N2 + 3F2
The nitrogen atom is 2 on both sides and fluorine has 6 atoms on both sides.
