Explanation:
At each reflecting surface (benzene and glass) there will be 180 degree phase change.
Now, for constructive interference the optical path in benzene is .
Formula to calculate thickness of a benzene thin film is as follows.
Optical path length through benzene () =
Hence, substituting the given values into the above formula as follows.
Optical path length through benzene =
d =
=
= (as 1 nm =
= 204.9 m
Thus, we can conclude that minimum thickness of benzene is 204.9 m.
Answer: The pull of the moon's gravity on Earth's water causes tidal bulges to form on the side closest to the moon and farthest from the moon. In the place where there are tidal bulges, high tide occurs along coastline.
Explanation:
Balanced equation:
2 moles of Al react with 6 moles of HCl. 2 moles of AlCl₃ and 3 moles of H₂ are produced.
The answer is C.
Answer:
<h2>36 atm </h2>
Explanation:
The pressure required can be found by using the formula for Boyle's law which is
Since we are finding the required pressure
From the question we have
We have the final answer as
<h3>36 atm</h3>
Hope this helps you
Answer:
The mass is 20, 89 grams of He.
Explanation:
We calculate the weight of 1 mol of He, from the atomic weight of each element obtained from the periodic table: Weight 1 mol He= 4, 0020602 g. 1 mol He-----4, 0020602 g. 5,22 mol He---x= (5,22 mol He x4, 0020602 g)/ 1 mol He= 20, 89 g
