5.(06.04B MC) In the following reaction, if you wanted to produce more hydrochloric acid (HCI), what should you do?
4HCI + O2 = 2H2O + Cl2 (2 points)
Add more H2O
Add more O2
Remove H20
Remove Cl2

Thanks!

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same

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.
