Amixture of dry air and nh3 enters an absorption tower at 80 of and 740 mm hg with 95 % saturation. water was used to absorbed part of the nh3. the gas leaves the tower at 730 mm hg and 60 oe and contains 0.2 % mol nh3 and is saturated with water vapor the nh3 in feed is absorbed. calculate what % of vapor pressure of ammonia at 80 of is 50 mm hg

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.

Select all that apply. using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 (s) pb+2(aq) + 2cl -(aq). the concentration of the products yield a ksp of 2.1 x 10-2:
