Answer:
Chlorine gas.
Explanation:
Hello!
In this case, the undergoing chemical reaction is:
[tex]2Na+Cl_2\rightarrow 2NaCl[/tex]
Thus, given the moles of reacting both sodium and chlorine, we compute the moles of sodium chloride yielded by each reactant by considering the 2:2 and 1:2 mole ratios:
[tex]n_{NaCl}^{by\ Na}=6.70molNa*\frac{2molNaCl}{2molNa}=6.70molNaCl \\\\n_{NaCl}^{by\ Cl_2}=3.20molCl_2*\frac{2molNaCl}{1molCl_2}=6.40molNaCl[/tex]
Thus, since chlorine yields less moles of sodium chloride, we infer it is the limiting reactant.
Best regards!
