I think it’s C. Marshmallow and toothpicks are used to show the composition of a water molecule
It occurs as detrital grains in sedimentary rocks. It forms under extreme pressure.
The chemical change occurred. Electrolysis is used by scientists to make chemical reactions that wouldnt normaly spontaniously ocur. In this case we are getting new gases from water molecul which is change in structure of elements ( we are getting new moleculs)
Explanation: White light is all colors of light in one, so when white light passes through a prism, the light gets refracted and breaks apart into all of the colors on the visible light spectrum.
