Answer: 4 moles of Na are needed to produce 4 moles of NaCl
Explanation:
The balanced chemical equation is :
[tex]2Na+Cl_2\rightarrow 2NaCl[/tex]
According to stoichiometry :
2 moles of [tex]NaCl[/tex] are formed from = 2 moles of [tex]Na[/tex]
Thus 4 moles of [tex]NaCl[/tex] will be formed from = [tex]\frac{2}{2}\times 4=4moles[/tex] of [tex]Na[/tex]
Thus 4 moles of Na are needed to produce 4 moles of NaCl
