Answer 1

Answer: 4 moles of Na are needed to produce 4 moles of NaCl

Step-by-step explanation:

The balanced chemical equation is :

`2Na+Cl_2\rightarrow 2NaCl`

According to stoichiometry :

2 moles of
`NaCl` are formed from = 2 moles of
`Na`

Thus 4 moles of
`NaCl` will be formed from =
`(2)/(2)* 4=4moles` of
`Na`

Thus 4 moles of Na are needed to produce 4 moles of NaCl
