7. Uranium-233 and Uranium-235 are the only two isotopes of uranium used as fuels in nuclear fission reactors. If you had 2.5 kg samples of each, which one would contain the least amount of the original
radioisotope after 1 billion years? Explain your answer. The half life of U-233 is 160,000 years, the
half-life of U-235 is about 700,000,000 years.

How many moles of carbon dioxide will form if 2.5 moles of c3h8 is burned

Which of the following best supports the concept that genetic information is passed on to offspring from both of their parents, not just one?

Since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, pbutane, alone. to do this, consult a reference and record the partial pressure of the water vapor, pwater, at the temperature you recorded. use the following formula to compute the partial pressure of the butane. pbutane = atmosphere - pwater use the following combined gas law formula and compute the volume that the butane sample will occupy at stp. (hint: convert both temperatures to kelvin.) pbutane x voriginal = pstandard x vfinal troom tstandard use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. grams of butane you used “x” grams of butane ml of butane corrected to stp = 22,400 ml compute the theoretical molar mass of butane based on its formula and the atomic masses on the periodic table. compare your experimental results from #3 to the theoretical value of #4, computing a percent error of your findings using this formula: % error = measured value - accepted value x 100 accepted value use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. need asap
