Answer:
.46 moles H2O2
3,014 grams Au
Explanation:
H2O2:
15.78g (1 mol/34g) = .46 moles H2O2
Au:
15.3mol (197g/mol) = 3,014 grams Au
The balanced chemical equation is :

Moles of
,

Now, by given chemical equation , we can see 2 mole of
react with 1 mole of
.
So , 2.27 mole react with :

Mass of oxygen is :

Therefore, mass of oxygen in grams produced is 18.16 g.
Hence, this is the required solution.
Answer:
#2.
Explanation:
Look at the charges. Both are positive, therefore both are cations.
