a. Calculate the minimum wavelength of light (in nm) that could break an oxygen-oxygen double bond given that it takes 499 kJ to break on mole of these bonds.
b. What portion of the electromagnetic spectrum does this wavelength of light correspond to? If this is in the visible region, what color of light would it be?
A 9.780 g. gaseous mixture contains ethane (C2H6) and propane (C3H8). Complete combustion to form carbon dioxide and water requires 1.120 mol of oxygen. Calculate the mass percent of ethane in the original mixture.
If 60.0g of Cu metal at 85C were added to 60.0g ethanol at 10C in a calorimeter of heat capacity 30.0 J/K what would the final temperature be assuming no heat losses? cp for Cu= 0.380 J/K/g and Cp for ethanol = 60.0 J/K/mol
