Calculate molar extinction coefficients from a UV visble spectrometer and use it to determine the geometry of complexes
The rate constant of a reaction is 2.6*10-3s^-1 at 25 c, and the activation energy is 33.6kJ/mol. What is k at
How many g of ethanol do I need to burn in excess oxygen in order to recover 5.0 g of water if the reaction has 75% yield
Starting with 2 different samples of propyne, show how you can make 2-methyl-pent-3-yn-2-ol (condensed formula (CH3)2C(OH)C=CCH3 ). In other words, you can convert propyne into a nucleophile, and convert propyne into an electrophile, and react the..
Write a balanced equation for the formation reaction of (a) HCl(g); (b) C6H6 (l); (c) CuSO4x5H2O (s); (d) CaCO3 (s, calcite). For each reaction, determine delta H not, delta S not, and delta G not from data in Appendix 2A.
