Classical instability of the H-atom: In the Bohr Model of the H-atom, an electron orbits the nucleus in a circle of radius r0. One serious problem with this model is that a charged particle moving in a circle is accelerating, and an accelerating charge radiates away EM energy according to the Larmor formula (Griffiths 11.70). So the H-atom will lose energy and the electron will quickly spiral into the nucleus, according to classical electrodynamics and mechanics. (a) Derive a formula for the total energy [U(r)

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .

your answer would be “dry”

answer: mole of the gas

answer: mole of the gasexplanation:

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
