Answer: 4.0 moles of sodium will react with water to produce 2.0 mol of hydrogen

Step-by-step explanation:

The balanced chemical equation is:


2Na(s)+2H_2O(l)\rightarrow 2NaOH(aq)+H_2(g)

According to stoichiometry :

1 mole of
H_2 is produced by = 2 moles of
Na

Thus 2.0 moles of
H_2 are produced by =
(2)/(1)* 2.0=4.0moles of
Na

Thus 4.0 moles of sodium will react with water to produce 2.0 mol of hydrogen
