A high school student developed the following model to explain indicators of a chemical reaction. Is the student’s model a correct representation of a chemical reaction taking place? Question 14 options: No, a chemical reaction always have more products than reactants. Yes, the model shows atoms rearranging to produce a new compound. No, a chemical reaction always produces more complex compounds. Yes, the model shows atoms changing states of matter to form a product.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
