Answer:
So the answer would be 10 moles
Explanation:
1) Start with the molecular formula for water: 
2) If there are 10 moles of water use a mole ratio to calculate the moles of oxygen it would produce.
(This question is... interesting... since they chose an element that is diatomic in free state so It could TECHNICALLY be two answers, moles of O or moles of 
)
The mole ratio is 1 moles of 
to 1 moles of O. This is because the coefficient for oxygen in water is simple 1, so the ratio is 1:1.
3) that means if 10 moles of water decompose, they decompose into 10 moles of 
and 10 moles of O.
Extra:
About what I was saying before about the question being slightly interesting:
10 moles of pure oxygen is produced but free state oxygen exists as so it could possibly be 10 OR 5! However, notice it says elements. This leads me to believe the answer is 10 (monatomic oxygen) instead of 5 (free state/diatomic oxygen).
I hope this helps!
Answer:
The amount of solute added.
Explanation:
The amount of solute added is directly proportional to the number of ions.
The higher the amount added the higher the number of moles.
The number of moles is multiplied by the Avogadro's constant to get the number ions.
No of ions= No of moles × L
L is the Avogadro's number.
Answer:
the changing tempure in rocks causing it to back apart
Answer:
B
Explanation:
B It’s a physical change because the water and the salt kept their original properties.
