One mole of CaCO3 (solid) is place in an evacuated cylinder that is fitted with a frictionless piston. It is heated to 800 degrees, at which point it decomposes to CaCO (solid) and CO2 (gas). Calculate the work done assuming complete decomposition at 1.00 bar. How much work would be done if there was no piston and the container was open to the atmosphere?
How much heat is released to the surroundings when 1.5 moles of water cools from 150 to 20 at 1 atm? Note that the constant pressure heat capacities, , for water in vapor and liquid form are 36.4 and 75.3 respectively.
Calculate the volume of carbon dioxide formed at a pressure of 2.50 atm and a temperature of 1250C.
How much heat is required to vaporize 25.5 g of water at 100 C? The heat of vaporization of water at 100 C is 40.7 rm kJ/mole.
Given the thermodynamic data in the data table below, calculate the equilibrium constant for the reaction: 2SO2 (g) + O2(g/0 2SO3(g), Substance Delta Hf (kj/mol) Delta S (J/K *mol)
A second 25.00-mL aliquot was then treated with an excess of BaCl2 and 25.00 mL of the base; precipitation of all the carbonate resulted, and 7.63 mL of the HCl was required to titrate the excess base. Calculate the composition of the mixture.
The equilibrium constant Kc for the decomposition of phosgene, COCl2, is 4.63 10-3 at 527°C. COCl2(g) CO(g) + Cl2(g) Calculate the equilibrium partial pressure of all the components
What is the calculated mass of K4Fe(CN)63h2o needed to prepare 100.00ml of .0250M solution. I just need help with the whole thing including units and significant figures.
Pure 2-methylpentane is held in a closed container at 150F. Both gas and liquid are present. What is the pressure in the container
What's the reaction mechanism when n-butyl acetate reacts with sodium bromide to form n-buytl bromide
When most Fe^3+ salts are dissolved in dilute nitric acid, the solution is often yellow to orange-yellow in color. Why could you not visually detect these colors in Fe(NO3)3 stock solution
N-Phenylmaleimide, can act as a dienophile in the Diels-Alder reaction Draw the structure of the product that would be formed by the treatment of N-phenylmaleimide with
what is the likely magnitude of the equilibrium constant K? Hydrogen is used as a rocket fuel because it is very light and reacts explosively and completely with oxygen. For the combustion reaction
