Answer to Question #240470 in General Chemistry for jboi

Question

how many moles of oxygen gas are produced when 0.500 mol of NA2O2 with water

Answer 1

Sodium peroxide reacts with water as follows

Na₂O_2(s) + 12 H₂O_(l)→2NaOH_(aq) +H₂O_2(aq)

As we can see from the reaction that oxygen is not evolved on reacting Sodium peroxide with water so we will get zero moles of oxygen on reacting 0.500 moles of Na₂O₂ with water.

We will get zero moles of oxygen.
