Find deltaH for the combustion of ethanol (C2H6O) to carbon dioxide and liquid water from the following data. The heat capacity of the bomb calorimeter
To resolve an object in an electron microscope, the wavelength of the electrons must be close to the diameter of the object. What kinetic energy must the electrons have in order to resolve a protein molecule that is 7.00 nm in diameter? Take the m..
A system at equilibrium contains I2 (g) at a pressure of 0.41 atm and I (g) at a pressure of 0.32 atm. The system is then compressed to half its volume. Find the pressure of I2 (g) when the system returns to equilibrium.
