As a system increases in volume, it absorbs 52.5 J of energy in the form of heat from the surroundings. The piston is working against a pressure of 0.500 atm. The final volume of the system is 58.0 L. What was the initial volume of the system if the internal energy of the system decreased by 102.5 J?
Determine the number of moles of O2 produced by the decomposition of 213 g of NaClO3.
The dispersion of a diffraction grating, such as the one shown at the right, is the angle of separation per μm of wavelength, Î"Φ /Î"λ
Given that the pKa for Acetic Acid is 4.77, calculate the expected pH of the buffer solutions using the Henderson-Hasselbalch equation and the concentrations of Acetic Acid and Acetate added to the 250 ml Erlenmeyer flask.
Many gases are shipped in high-pressure containers. Consider a steel tank whose volume is 65.0L and which contains O2 gas at a pressure of 16,500kPa at 23°C.
How many carbon dioxide molecules are generated by the combustion of one molecule of hexane (C7H14) in ample oxygen?
Ethanethiol is more soluble in water because sulfer has agreater electronegativity value than oxygen. Ethanethiol is more soluble in water because it has a lower molecular mass than 1-propanol.
Calculate the maximum wavelength of light with sufficient energy to dissociate a diatomic chlorine molecule into chlorine radicals.
