The united states uses 1.4×1019 j of electrical energy per year. assume, that all this energy came from the fission of 235u, which releases 200 mev per fission event. assume that all fission energy is converted into electrical energy. part a how many kilograms of 235u would be used per year? express your answer to two significant figures and include the appropriate units. m m = nothing nothing request answer part b how many kilograms of uranium would have to be mined per year to provide that much 235u? (recall that only 0.70% of naturally occurring uranium is 235u.) express your answer to two significant figures and include the appropriate units.

Consider the reaction 2x2y2+z2⇌2x2y2z which has a rate law of rate= k[x2y2][z2] select a possible mechanism for the reaction.

For this option, you will work individually. the pythagorean theorem can be used in many real-world scenarios. part 1 write your own real-world scenario where the pythagorean theorem can be applied to find a missing piece. you may choose to write a problem that is two- or three-dimensional in nature. be sure that you will be able to draw a diagram of your scenario. write out your problem and submit it for part 1. be sure to end your scenario with a question. part 2 draw a diagram of the scenario you created in part 1. you may draw by hand and scan and upload your drawing or create a computer-generated drawing for submission. be sure to label all parts and dimensions of the drawing. part 3 solve the question that you posed in part 1. show all of your steps in answering the question. for this option, you will need to submit all three parts for full credit—your real-world problem and question, the diagram that you created, and your work solving the problem, showing all steps. * note that your instructor is looking for your own original idea. while it is acceptable to use the internet for research and inspiration, academic integrity policies apply.
