Draw the electronic absorption spectrum (applying the 1st- order approximation) for peroxide, and briefly explain whether peroxide is paramagnetic or diamagnetic and how it would interact with a magnetic field?
0.032 moles of balls, what are the steps the manager would follow to determine how many balls there are and calculate the final total.
The enthalpy of combustion of acetylene C2H2 is C2H2(g) + 5/2O2(g) ->2CO2(g) + H2O(l) H°rxn= -1299 kJ Calculate the enthalpy of formation of acetylene, given the following enthalpies of formation H°f[CO2(g)] = -393.5 kJ/mol ,H°f[H2O(l)] = -285.8 k..
Suppose you have a mixture of the following solids: iodine (I2), benzophenone (H5C6-C(=O)-C6H5), benzoic acid (C6H5-C(=O)-OH), and oxalic acid (HOOC-COOH). You dissolve a small quantity of the solid mixture in ethanol and spot the solution on a TL..
A 585 g piece of copper tubing is heated to 97.2°C and placed in an insulated vessel containing 51.0 g of water at 26.0°C.

Based on their reduction potentials, what are the most likely cathode products in the electrolysis of an aqueous solution containing 1M LiCl, 1M FeCl2 and 1M CoCl2
A sample of ammonia gas is completely decomposed to nitrogen andhydrogen gases over heated iron wool. If the total pressure is 603mmHg, calculate the partial pressure of N2 and H2
A. In Lewis theory, the two bonds in a double bond look identical. However, valence bond theory shows that they are not.
Reaction of AsCl3 with Cl2 at low temperature yields a product, believed to be AsCl5, which shows Raman bands at 437,369, 295, 220,213, and 3cm-1. Detailed analysis of the 369 and 295 cm-1 bands show them to arise from totally symmetric modes.
