Answer:
D. 0.063 mol
Explanation:
We can calculate the number of moles by using the <em>definition of molarity</em>:
- Molarity = moles / liters
As we are given both the <em>molarity and the volume</em>:
We can <u>calculate the number of moles</u>:
Thus the answer is option D.
Answer:
C.
Explanation:
This is a reaction of elimination, because the water was removed and because of it double bond is formed.
Explanation:
As the given reaction equation is as follows.
Hence, expression for of this reaction is as follows.
Now, putting the given values into the above expression as follows.
=
=
Thus, we can conclude that the value of is .
4Na + O2 - 2Na2O
Moles= 4:1 ratio
3.82 x 4 = 15.28 moles
Answer:
