Use the observations about each chemical reaction in the table below to decide the sign (positive or negative) of the reaction enthalpy AH and reaction entropy A.S. Note: if you have not been given enough information to decide a sign, select the "unknown" option. reaction A B с observations This reaction is always spontaneous, but proceeds faster at temperatures above 76. °C. This reaction is spontaneous only above -1. °C but proceeds at a faster rate above 42. °C. The reaction is never spontaneous. conclusions AH is (pick one) (pick one) AS is AH is AS is AH is AS is positive negative unknown (pick one) (pick one) ✓ (pick one) ✓ (pick one)

How many neutrons does a 81Br1- anion have?
Please only answer part b. Thank you! (b) The negative muon (μ−) behaves like a heavy electron, with the same charge as the electron but with a mass 207 times as large as the electron mass. As a moving μ− comes to rest in matter, it tends to knock electrons out of atoms and settle down onto a nucleus to form a "one-muon" atom. For a system consisting of a nucleus of platinum (Pt195 with 78 protons and 117 neutrons) and just one negative muon, predict the energy in eV of a photon emitted in a transition from the first excited state to the ground state. The high-energy photons emitted by transitions between energy levels in such "muonic atoms" are easily observed in experiments with muons.
