(a) Given a cyclohexane framework in a chair conformation, label each position as axial (ax.) or equatorial (eq.). (b) On the same figure, label all positions that are gauche (ga.) to the Y group on carbon 1. A bin may hold more than one label.

The equilibrium constant, Kp, equals 3.40 for the isomerization reaction: cis-2-butene trans-2-butene If a flask initially contains 0.250 atm of cis-2-butene and 0.145 atm of trans-2-butene, what is the equilibrium pressure of each gas?

Determine the relative error for the following quantities If there is no uncertainty given for a specific value, assume an absolute error of 1 in the last digit. For example, if there is no uncertainty provided for the value of 0.024, you will assume the absolute error to be 0.001 or 0.0240.001 (i.e. an uncertainty of 1 in the last significant

Part A - Practice Reading and Comparing Graphs Consider the following graph containing line plots for the moles of Product 1 versus time (minutes) and the moles of Product 2 versus time in minutes. The plot shows product amount in moles as a function of time in minutes. There are two curves: for product 1 and for product 2. Both curves start at

Product Amount (moles) 1 Product 1 B (12,10) Product 2 A (12,5) Time (minutes)

The emission spectrum below for a oneelectron (hydrogenlike) species in the gas phase shows all the lines, before they merge together, resulting from transitions to the first excited state from higher energy states. Line A has a wavelength of 434 nm. Increasing wavelength, A (a) What are the upper and lower principal quantum numbers
