Calculate the mean free path and the binary number of collisions per liter per second between HI molecules at 300 K and 1.00 atm. The collision diameter of the HI molecules may be taken to be 5.10 A. Assume ideal-gas behavior.
Fifty percent of that sunlight is captured by the collector and heats the water flowing through it. What would be the temperature rise of the water as it leaves the collector?
Sucrose (C12H22O11, table sugar) is oxidized in the body by O2 via a complex set of reactions that ultimately produces CO2(g) and H2O(g) and releases 5.64 x 103 kJ/mol sucrose. What is q (heat change) per gram of sucrose oxidized
A solution is prepared by condensing 5.01L of a gas, measured at 27.0 degrees celcius and 769 mmHg pressure, into 72.1g of benzene. Calculate the freezing point of this solution.
The final volume of the balloon is 1500 mL. The atmospheric pressure is 1.00 atm. What was the original pressure of HI in the cylinder before the release of HI
Nitartion of ferrocene not possible why, Ferrocene cannot be nitrated using the conventional HNO3-H2SO4 mixed acid conditions, even though nitration is an electrophilic aromatic substitution reaction. Explain.
what is the order of increasing steric hindrance within these reactions and what is the reason for that order in terms of calculated energies, distance, and structures.
Assume your solution contains lead and iron but not silver or nickel. Explain how will you know that: - Either silver or lead is present ( that is, describe what you will see that will tell you at least one of these is there)
A collapsed balloon is filled with He to a volume of 11.2L at a pressure of 1.00 atm. Oxygen (O2) is then assed so that the final volume of the ballon is 21
A 4.78 L sample of H2O(g) reacts at a temperature of 375°C and a pressure of 692 mm Hg. How many grams of NH3 can be produced?
Briefly explain whether the following procedural errors would result in either an incorrectly high or incorrectly low calculated percent Cu recovery for this experiment.
A cylinder contains 28.5L of oxygen gas at a pressure of 1.8 atm and a temperature of 298k. How much gas (in moles) is in the cylinder
if the empty cylinder has the mass of 94.2g and the cylinder with water has the mass of 138.7 g what is the mass of water, volume of water and the density of water.
