Answer:
Explanation:
Q3.What did you observe about the wavelengths and frequencies of the different colors of light?
Q4. Do the frequencies of colors of light increase from red to violet?
Q5. What did you observe about the corresponding energies from red to violet?
wavelength times frequency =c=the speed of light
the higher the frequency, the shorter the wavelength
the different colors of visible light are our good friend ROY G BIV
RED ORANGE YELLOW GREEN BLUE INDIGO VIOLET
As we go from red to violet, the wavelength decreases and the energy increases because the wave is vibrating at a higher number of vibrations per secomd. This is what "frequency' means, how many vibrations are there per second, how FREQUENT are thee.
the higher the frequency the more energy because the wave is vibrating faster.
the equation that relates this is Energy = h times frequency, where h is
Planck's constant = 6.262 x 10^-27 ERG-SEC
the frequency of vibration and therefor the energy of visible electromagnetic radiation (light) increase as we go across
ROY G BIV
Answer : The mass of Ni is, 80.346 g
Solution :
First we have to calculate the number of moles.
Now we have to calculate the number of atoms of 
As 1 moles contains 
number of molecules
So, 1.369 moles contains 
number of molecules
One molecule has one nitrogen atom then number of molecules of will contain number of nitrogen atoms
As per question number of Ni atoms is equal to the number of nitrogen atoms
Number of Ni atoms= atoms
Number of moles = 
Mass of Nickel = 
Molecular mass of Nickel = 58.69 g/mol
Mass of nickel =
