Find out the amount number of mol of negative charge present in a sample of an ionic compound that contains 23.1 g of a 3- anion whose molar mass MM is 96.07 g/mol.
Please contraste the ideas of Prebisch, Frank, Reinert and various structuralists and dependency theorists with the conclusions
many people think salt is added to water to increase the boiling poing so pasta will cook faster. how much salt would
If we assume that the atmosphere of the earth is an ideal gas mixture, then each component is described by a separate barometric equation. This model predicts that the concentrations of heavier molecules, and therefore their partial pressures, dec..
How many moles of carbon dioxide would have to be added at constant temperature and volume to increase the amount of carbon monoxide to 0.300 mol once equilibrium has been reestablished?
An unknown metal m reacts with sulfur to form a compound with te formula M2S3. If 3.12g of m reacts with 2.88g of S, what are the names of M AND M2S3
a. A solid in contact with a gas at 12 kPa and 25°C adsorbs 2.5 mg of the gas and obeys the Langmuir isotherm. The enthalpy change when 1.00 mmol of the adsorbed gas is desorbed is +10.2 J. What is the equilibrium pressure for the adsorption of 2.5 m..
Hydrocarbons are often reacted with steam to form H2, as shown for propane- C3H8(g) + 6 H2O(g) 3 CO2(g) + 10 H2(g) Calculate Kp for this reaction at a particular temperature
