The equation demonstrates a reaction of sodium chloride and fluorine.


2NaCl + F2 → 2NaF + Cl2

In order for the reaction to proceed, for every two moles of sodium chloride, there must be at least how many mole(s) of fluorine?

the equation clearly shows just one mole of F2

Note that "moles of fluorine" means moles of F2, not moles of F.
Why is that?

To balance the equation and ensure that the reaction proceeds, there must be at least one mole of fluorine for every two moles of sodium chloride.

To determine how many moles of fluorine are needed for the reaction to proceed, we need to examine the balanced equation:

2NaCl + F2 → 2NaF + Cl2

According to the equation, for every 2 moles of sodium chloride (NaCl), there are 1 mole of fluorine (F2) required.

So, to find out how many moles of fluorine are needed, we can set up a ratio:

2 moles NaCl : 1 mole F2

From this ratio, we can deduce that at least 1 mole of fluorine is needed for every 2 moles of sodium chloride.

Therefore, the reaction can proceed if there is at least 1 mole of fluorine present.
