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
Step-by-step 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.
