Recall all the models you described in task 1. think about the results each model would predict for rutherford’s experiment. which atomic models does rutherford’s experimental evidence support? explain why these models are compatible with the experimental results.

You are performing an experiment in a lab to attempt a new method of producing pure elements from compounds. the only problem is that you do not know what element will form. by your previous calculations you know that you will have 6.3 moles of product. when it is complete, you weigh it and determine you have 604.4 grams. what element have you produced?

12. calculate the hydroxide ion concentration of a solution with ph = 3.25. show all calculations leading to an answer

Imagine that you push on a large rock. at what point does your effort change the rock’s mechanical energy?
