Write an equation for the reaction of iodine in aqueous solution to form iodate ion and iodide ion under acidic conditions, then calculate the electrochemical potential for the reactionPlease write out half reactions and include as much work as possible for explanation.
The heat of vaporization of water is 9.72 Kcal/mol.How much heat (in kilocalories) is required to vaporize 2.70 mol of H2O and how much heat (in kilocalories) is released when 440 grams of steam condenses
Consider a buffer by dissolving .139 M sodium benzoate and .081 M benzoic acid in water and adjusting the final volume of the solution to 500 mL. pKa of benzoic acid = 4.19. What is the pH of the buffer
what is the minimum pressure in kpa that must be applied at 25 degc to obtain pure water by reverse osmosis from water
when heated, sulfuric acid will decompose into sulfur trioxide and water
what is the process for drawing them? is there a procedure to follow to be able to draw the lewis structure of any
Given below is a table ...on the right are the molarities and percent transmittance (at fixed path length and wavelength) For three known solutions and an unknown solution of a compound in water: Which one of the following values is possible as the m..
An equilibrium mixture of PCl5(g), PCl3(g), and Cl2(g) has partial pressures of 217.0 Torr, 13.2 Torr, and 13.2 Torr, respectively. A quantity of Cl2(g) is injected into the mixture, and the total pressure jumps to 263.0 Torr.
If a chalice made of pure gold weighing 1.47 kg as well as initially at 21 C is filled with 150.0mL of water at 78 C, explain what is the final equilibrium temperature of the system. The heat capacities of water as well as gold are 75.29 and 25.42..
The normal boiling point of ethanol is 78.4 degrees C, and at this temperature ?vapHθ = 38.7 KJ mol-1. Calculate the value to which the pressure must be reduced to boil ethanol at 25 degrees C in a vacuum distillation.
