Aluminum chloride can be formed from its elements:
(i) 2Al(s)+3Cl2(g)⟶2AlCl3(s) ΔH°= ?
Use the reactions here to determine the ΔH° for reaction (i):
(ii) HCl(g)⟶HCl(aq) ΔH∘(ii)=−74.8kJ
(iii) H2(g)+Cl2(g)⟶2HCl(g) ΔH∘(iii)=−185kJ
(iv) AlCl3(aq)⟶AlCl3(s) ΔH∘(iv)=+323kJ
(v) 2Al(s)+6HCl(aq)⟶2AlCl3(aq)+3H2(g) ΔH∘(v)=−1049kJ

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.
