Plagiarism is when you just copy exactly what someone else says, without their permission, or without citing where you got it from.
Common knowledge should be your own words. unless you take it from somewhere else, it doesnt need anything.
<u>Answer:</u> The spacing between the crystal planes is 
<u>Explanation:</u>
To calculate the spacing between the crystal planes, we use the equation given by Bragg, which is:
where,
n = order of diffraction = 2
= wavelength of the light = 
(Conversion factor: 
)
d = spacing between the crystal planes = ?
= angle of diffraction = 22.20°
Putting values in above equation, we get:
Hence, the spacing between the crystal planes is
Answer:
Depends on different states.
Explanation:
The wavelength of the photon that is emitted from the atom during the transition depends on the transition from different states. If the photon is emitted from n=4 state to n=3 state, the wavelength of photon is 1875 while on the other hand, if the photon is emitted from n=5 state to n=3 state, the wavelength of photon is 1282. If the photon is emitted from n=3 state to n=2 state, the wavelength of photon is 656.
Answer: Boiling chips provide surfaces on which bubbles can form as the liquid boils.
Hope this helps!
The answer is c O2:H2O
502:6H2O
SO THAT IS 5:6
