- A carbon atom, with a half-full outer shell of electrons—four in a shell that can hold eight—readily shares its electrons with other atoms and forms a vast number of molecules, many of which are the organic molecules that form the bulk of living matter. Looking at the periodic table, what other element do you think might play a role like carbon in life forms on some other planet?arrow_forwardThis lab has two goals: (1) to determine the specific heat of an unknown metal, (2) to determine the latent heat of fusion for H2O.arrow_forwardQuestion: A Coal Sample Gave The Following Analysis By Weight, Carbon 66.9 Per Cent, Hydrogen 6.58 Per Cent, Oxygen 8.77 Per Cent,...

- Lithium has only two naturally occuring isotopes: lithiumi-6 and lithium-7. Lithium-6 has a mass of 6.01512 and makes up 7.42 percent of all naturally occuring lithium. Lithium-7 has a mass of 7.016 and makes up the remaining 92.58 percent. What is the atomic mass of lithium?arrow_forwardPotassium is a crucial element for the healthy operation of the human body. Potassium occurs naturally in our environment (and thus our bodies) as three isotopes: Potassium-39, Potassium-40, and Potassium-41. Their current abundances are 93.26%, 0.012% and 6.728%. A typical human body contains about 3.0 grams of Potassium per kilogram of body mass. How much Potassium-40 is present in a person with a mass of 80 kg? If, on average, the decay of Potassium-40 results in 1.10 MeV of energy absorbed, determine the effective dose (in Sieverts) per year due to Potassium-40 in an 80-kg body. Assume an RBE of 1.2. The half-life of Potassium-40 is 1.28 x 109 years.arrow_forwardWhat are the masses of sulfur’s two most dominant isotopes? Which ones are capable of generating NMR signals?arrow_forward
