Using the periodic table, which isotope is probably the most abundant isotope of potassium (K)? 41 K 39 K 38.10 K 19 K 40 K Lithium forms compounds which are used in dry cells and storage batteries and in high-temperature lubricants. It has two naturally occurring isotopes, Li (atomic mass = 6.015121 amu) and 7Li (atomic mass 7.016003 amu). What is the percent abundance of lithium-6? You should use the periodic table to help you answer this. 7.5% 92.5% 86.7%...
The mass density of silver at room temperature is 10.5 x 103 kg/m3 and its atomic mass is 108g/mol. If we assume there is one free electron per silver atom, what is the free-electron desity for silver, in electrons/m3? How does this compare to the free electron density of Copper?
2. 23 U is a fissile isotope of uranium, used in the atomic bomb dropped on Hiroshima in 1945. The critical mass is 56 kg. The primary isotope is not fissile and had to be removed by a process which required synthesis of UFs, a gas. How much 235UF was required to produce a critical mass of the element? [Molar masses: U, 235.0439 g; F, 18.9984 g)

D | Question 4 1 pts Which of the resonance forms provided contributes least to the resonance hybrid for CH20? H C-H :O All provided forms contribute equally
Enter your answer in the provided box. The 235U isotope (atomic mass = 235.00) undergoes fission when bombarded with neutrons. However, its natural abundance is only 0.72 percent. To separate it from the more abundant 238U isotope (atomic mass = 238.00), uranium is first converted to UF, which is easily vaporized above room temperature. The mixture of 23SUF, and 238UF gases is then subjected to many stages of effusion. Calculate how much more quickly 235UF, effuses than 238UF. Give the...
