N2(g) + 3H2(g) ⇌ 2NH3(g) At equilibrium [N2] = 0.0800M , [NH3] = 1.80M , The Keq = 8.70
Calculate the[ H2].

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums? (2 points) the spectrum of a motionless star is difficult to be viewed separately using oridinary telescopes. the spectrum of a motionless star is identical to the spectrum of a star which moves towards earth. the spectrum of a star shifts towards the red region when the star moves towards earth. the spectrum of a star shifts towards the blue region when the star moves towards earth.
