I have a chemistry scavenger hunt project and I need help finding an example of the following and also the reasoning behind it. Illustrate the difference between weight and mass, a hydrocarbon, a covalent molecule, ions, a material other than water that undergoes sublimation, and describe the difference between fusion and fission-- diagram and models may be used
Answer:
Its a good thing you can bring in a diagram, otherwise your last request would require a nuclear bomb.
Here are some ideas
covalent molecule - sugar
sublimating material - iodine
hydrocarbon - candle
ions - salt
F=ma
F=GmM/r^2
