3. A simple model of a Neutron star is an ideal gas of neutrons (each with spin 1/2 in units of h). Aside from the kinetic energy of the neutrons, one must consider the gravitational energy, which for a homogeneous star of mass M and radius R, is 3GM2 5R where G 6.67 x 10-11m3kg-'s-2 is the universal gravitational constant (i) We suppose in this problem that the Fermi temperature is large enough for T0 What general condition determines the...

Consider a simplified model of a triply ionized beryllium-9 atom (Be^1+): four protons plus five neutrons in the atom's nucleus, "orbited" by just one electron at a constant distance of 4.50 times 10^-12 m. You can solve (a) & (b) in either order. Label your work clearly: a. What is the strength (magnitude) of the attractive electric force between the nucleus and the electron? Show your work. b. What is the magnitude of the electric field at the electron's location?...

1.) An isotope has 9 protons and 10 neutrons. The isotope has a charge of -1. How many electrons does this isotope have? 2.) An atom called X is bonded to another atom by a triple bond. What is the maximum number of additional atoms that can be bonded to X and still conform to the octet rule? 3.) One tablet of Tums antacid contains 500.0 mg of calcium carbonate. When calcium carbonate reacts with hydrochloric acid (from gastric juices), carbon dioxide gas,...
