For homonuclear diatomic molecules, two atomic orbitals of the same energy interact. In hydrogen gas (H2), sketch (or describe) the result of such interaction?
1. Ideal gas with internal degrees of freedom. Consider a free gas of diatomic molecules at temperature 7. Diatomic molecules have internal rotational excitations. The rotational energy levels of a single molecule are given by J(J+1) 2/2 J = 0,1,23 where J is the angular momentum and I is the moment of inertia. The degeneracy of the level J is 2J +1. Neglect any interaction between the molecules in the gas. The temperature is high enough so that the statistic...
15. Use the Ideal Gas Law and the answers to questions 12, 13 and 14 to calculate the number of moles of hydrogen gas present. R 0.0821 Leatm/mol K (watch sig figs.) 16. A student reacted 0.7655 g of chromium (at. wt - 51.996 g/mol) with exactly 1.566 g of chlorine (at. wt. - 35.453 g/mol). Convert both these masses to moles and determine the empirical formula (like AX) of the compound of Cr and CL SHOW YOUR WORK 17....

Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
