What is the Appropriate half-reactions for the Haber process? Explain.
What are Two environmental aspects of the Haber process? Explain.
Magnesium metal is easily deformed by an applied force, whereas magnesium fluoride is shattered. Why do these two solids behave so differently
When 1.28 mg of hydrogen peroxide decomposes in the presence of manganese dioxide to form water and oxygen, how many miligrams of each are produced?
The mass percent of a three component gas sample is 58.0% C2H4O2, 14.6% NH3 and 27.4% CH2O. Calculate the partial pressure (atm) of CH2O if the total pressure of the sample is 0.340 atm.
Question- The sun emits many wavelengths of light. The brightest light is emitted at about 0.483 um. What frequency (in Hz) does this corresponds to?
Explain why the first ionization energy trend tends to increase as one proceeds left to right across a period. Why is the first ionization of aluminum lower than that of magnesium and the first ionization of sulfer lower than that of phosphorus
What mass of sucrose should be combined with 493 g of water to make a solution with an osmotic pressure of 9.00 atm at 320 K? (Assume the density of the solution to be equal to the density of the solvent.)
15.00mL of radiator liquid (water + ethylene glycol) from a car has a mass of 15.69g. Is the denisty of ethylene glycol greater or less than that of water. Explain.
At equilibrium the vessel contains 0.40 mol of PCl3 (g) as well as Cl2(g) and undissociated PCL5(g). What is the equilibrium constant for the decomposition of PCl5 to PCl3 and Cl2 at this temperature.
Ammonia will react with oxygen in the presence of a copper catalyst to form nitrogen and water. From 164.5 degrees C to 179 degrees C, the rate constant increases by a factor of 4.27. What is the activation energy of this oxidation reaction
Calculating the Moles of Aspirin, The molecular formula for aspirin is HC9H7O4, Calculate the molecular weight for aspirin
What is the change in entropy in entropy in the system in J/K when 39.3 grams of steam at 1 atm condenses to a liquid at the normal boiling point.
A deep-sea diver uses a gas cylinder with a volume of 10.0 L and a content of 51.0g of O2 and 32.5g of He. Calculate the partial pressure of each gas and the total pressure if the temperature of the gas is 15 deg C.
