Hydrogen sulfide is composed of two elements: hydrogen and sulfur. in an experiment, 6.500 g of hydrogen sulfide is fully decomposed into its elements. (a) if 0.384 g of hydrogen is obtained in this experiment, how many grams of sulfur must be obtained? (b) what fundamental law does this experiment demonstrate? (c) how is this law explained by dalton’s atomic

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.
