How do you explain the principle of the red shift?
It indicates if a object is moving away.
How are blue shift and red shift the same?
Light received by an observer is affected if the observer or the source are moving towards or away from one another. This is the Doppler Effect.This is sort of like a race car.As it's approaching you, its noise sounds higher in pitch, and lower in pitch as it's moving away from you.Light waves - just like sound waves - are affected by relative movement between the observer and source.When the observer is moving away from the light source, the light is shifted to the red end of the light spectrum. The light waves are "stretched". There is further between the peaks of the wave.So, the wavelength increases. That means a shift from blue to red in the spectrum.By convention, the shift towards longer wavelengths is called a redshift.In fact, red light could be shifted to infrared."Redshift" just means a change in the observed light towards longer wavelengths.When the observer is moving towards the light source, th light shifts to the blue end of the light spectrum. We call that a blueshift.Redshifts can also be caused by the effect of gravity.Answer2:Redshift by gravity is F =mGM/r2= vp/rvp/r=vp/ct=(v/c)p/t = (v/c)mv/t = (v/c)ma.Gravity creates the velocity v and v/c is the "redshift" due to gravity v and not due to universe expansion of the recession of the body. The redshift of the earth is v/c = 30k/300M = 1/10k.
What did Hubble use to attempt to prove his theory?
he discovered that there were millions of other galaxies... making the universe unimaginably larger than previously thought. And he discovered that the light from distant galaxies is Red-shifted, and that the further the galaxy is, the more red-shifted its light. This not only demonstrated that the universe was expanding... It ultimately led to the formation of Big Bang theory by working out this expansion in reverse.

Is ammonia neutral?
Ammonia (NH₃) is neutral, however if you add a hydrogen atom, it becomes a positive ammonium molecule (NH₄⁺). Also, ammonia dissociates into it's conjugate acid and conjugate base (which neutralize each other): 2NH₃ ⇌ NH₄⁺ + NH₂⁻
What is a biuret?
A biuret is the compound formed by the condensation of two molecules of urea with the loss of a molecule of ammonia, (NH2-CO)2NH or any of its derivatives.

Nitric oxide gas reacts with hydrogen gas to form ammonia gas and water vapor?
2NO+5H(subscript 2)----->2NH(subscript 3)+2H(subscript 2)O
How many moles of nitrogen are required to react with 3.4 moles of hydrogen to form ammonia feterlizer?
To form ammonia, reaction is N(2) + 3H(2) ---> 2NH(3) + H(2)O. As you can see for 1 mole of nitrogen three moles of hydrogen is required. Hence for your question, 1.13 moles nitrogen is required.
How many moles of nitrogen are needed to convert 9.0 mole hydrogen gas to ammonia gas?
To form ammonia, balanced reaction is N(2) + 3H(2) ---> 2NH(3) + H(2)O. As you can see for 1 mole of nitrogen three moles of hydrogen is required. Hence for your question, 3 moles nitrogen is required to satisfy the ratio.

Determine the speed of an electron moving in a circle about the proton using the attractive electric force between an electron and a proton separated by this distan?
E=zce^2/4pi r = mv^2 =nhv/w wherer w is the wavelength.zce^2/2w = nhv/w and v= zce^2/2nh = c Alpha/n where Alpha is the Fine Structure Constant 7.2e-3.V= 7.2e-3c/n = 2.16e6/n m/s. The speed of the electron is 2.16 mega m/s when n=1 the lowest level.
