A sample of a gas in an 11.2 L container is at 1.0 atm and 0°C, as shown. The mass of the sample is 16 g Which of the following is most likely to be the identity of the gas, and why? SOs, because there is 0.25 mol of gas in the container and the mass of 0.25 mol of SO, is 16 %
Oz, because there is 0.50 mol of gas in the container and the mass of 0.50 mol of O, is 16 g
CH, because there is 1.0 mol of gas in the container and the mass of 1.0 mol of CH is 16
He, because there are 4.0 mol of gas in the container and the mass of 4.0 mol of He is 16g

The table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.

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.
