In the reaction, fluorine and chlorine are present as reactants. Fluorine is a stronger oxidizing agent than chlorine, as fluorine has the tendency to be reduced. Keep in mind that oxidation is when there is an increase in the oxidation number of a substance and reduction is when there is a decrease in the oxidation number. Therefore, the correct statement becomes:
Cl- oxidizes to Cl and F reduces to F-.
Assuming ideal gas law applies to the problem, we find the pressure from the given volume, temperature and number of moles. The ideal gas equation is PV=nRT. R is 0.0821 L atm/ mol K. Substituting the data given, P= (2.50 moles)(0.0821 L atm/ mol K)(27+273 K)/(50 L)= 1.2315 atm. This is equivalent to 936 mm Hg.
The answer I believe would be A
It will react by being a chemical change because something new is formed
