What is the theoretical number of moles of hydrogen gas should be produced when 0.068 mol of sodium metal reacts?

Respuesta :

transitionstate
Sodium Metal when reacted with water produces Hydrogen gas and NaOH,

                     2 Na (s) + 2 H₂O (l)    →    2 NaOH (aq)  +  H₂ (g)

According to equation,

                     2 moles of Na produces  =  1 mole of H₂ gas
So,
          0.068 moles of Na will produce  =  X moles of H₂ gas

Solving for X,
                        X  =  (0.068 mol × 1 mol) ÷ 2 mol

                        X  =  0.034 moles of H₂
