Answer:
c. F1-
Explanation:
In this chemical reaction the expression is:
HF + NaF → NaHF2
The ion that always keep the negative charge is the fluorine with a -1, if in this mixture there is more positive ions (H1+) the negative ion (F1-) will join with them.
Remember that also the Cl1- will be free, but the fluorine is more reactive than the fluorine.
Both are caused by human ignorance. Both have the ability to kill those in them. Both can become compact to create new material.
C6H12O6 +6O2 —> 6CO2 + 6H2O
