PLEASE HELP! 35 POINTS I just don't understand. First evaluate these three models. One represents fission, one fusion, and one radioactive decay. Write three sentences about each one according to the following framework:
1. State what reaction the model represents, including what it demonstrates about mass and/or energy.
2. State whether you think the model accurately represents the reaction. Explain why or why not.
3. Suggest one way to improve the model.

Model A: Two sponge balls representing two atoms are soaked in water. You hold one ball, and your friend holds the other. Then you press the two balls together. As you press them together, water leaks out. What type of reaction does this model represent?
Model B: You draw a tree diagram showing a large atom splitting into two parts and neutrons being released. Your diagram also shows the released neutrons hitting other large atoms, which then each split in two and release more neutrons, which hit more large atoms, and so on. What type of reaction does this model represent?
Model C: You have 100 candies with the letter "M" on one side. You pour the candies into a pan. You count and remove all the candies with the "M" facing upward. Then you shake the pan and again count and remove all the candies with "M" facing upward. You shake, count, and remove candies four more times. What type of reaction does this model represent?
