Explanation:
Answer : The mass of oxygen will be, 36.8 grams
Solution : Given,
Moles of water = 2.30 moles
Molar mass of
= 32 g/mole
First we have to calculate the moles of oxygen.
The balanced chemical reaction will be,

From the balanced reaction we conclude that
2 moles of water decomposes to give 1 mole of 
2.30 moles of water decomposes to give
moles of 
Now we have to calculate the mass of oxygen.


Therefore, the mass of oxygen will be, 36.8 grams
Answer:
Triphorphorus Pentanitride
Explanation:
since there are three phosphorus use the prefix tri-, since there are five nitrogen use the prefix penta. tri=3, penta=5. then add a suffix -ide to the end of nitrogen. that will give you triphosphorus pentanitride.
The answer is A because it does
