Question

165. How many moles of sodium will react with water to

produce 4.0 mol of hydrogen in the following reac-
tion?
2Na(s) + 2H2O(l) + 2NaOH(aq) + H2(g)

Answer 1

Step-by-step explanation:

Hello,

In this case, based on the given rewritten reaction:

The stoichiometry leads to the following theoretical moles of oxygen:

As sodium and hydrogen as a 2 to 1 molar relationship.

Step-by-step explanation:

Answer 2

mol Na (s) = (4.0 mol H2 (g) ) * ( 2 mol Na (s) / 1 mol H2 (g) ) = 8.0 mol Na (s)
