The potential energy of the two atoms in a diatomic (two-atom) molecule can be written b U(r) = − 6 +12, where r is the distance between the two atoms and a and b are positive constants. 10月 13 Part A Determine the binding energy for this molecule.

十一、 (1) 請求出由溶解1克的甘胺醯胺氯化氢(pKa 值 8.2,分子量為110.54) 與1克的甘胺醯 胺(分子量為74.08)配製成 0.1L 溶液的 pH 值? (2) 1 克的甘胺醯胺氯化氢(pKa 值 8.2,分子量 為 110.54),需加入多少克的甘胺醯胺(分子 量為 74.08)才能配製成 100mL、pH 值為 8 的溶液? (3) 如果(1)的溶液與 5mL 之 0.1M HC1混合,pH 會變為多少? (4) 如果(3)的溶液與 10mL 之 0.1M NaOH 混 合,pH 會變為多少?

近代物理求解：

Problem 28. Consider the process A* + A+), and A* is stationary (at rest). This is the process that an excited atom emits a photon and goes back to the ground state atom A. Assume that the excited atom has a rest mass M6. Show that v-mi (loro) hvo (4.3.14) = 1 2M where v is the photon frequency if the recoil is taken into account, and vo is the photon frequency if the recoil is not taken into account.
