How many moles of oxygen gas are produced when 0.500 mol #Na_2O_2# reacts with water?

Answer 1

As far as I know NONE.....

Dioxygen gas can be produced through thermolyzing sodium peroxide.

#Na_2O_2(s) +Delta rarr Na_2O(s) + 1/2O_2(g)uarr#

However, all that occurs when we use water is an acid-base reaction.

#Na_2O_2(s) +2H_2O(l) rarr 2NaOH(aq) + H_2O_2(aq)#...

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
