The law of mass conservationis another fundamental law in chemistry. This law states that matter can neither be created nor destroyed, which means that in a chemical reaction where all of the reactants is converted into products, the mass of reactant that reacts must be exactly equal to the mass of product produced. Next week you are going totest the law of mass conservation. To do this you will need to design your own experiment

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.
