Determine the enthalpy change for the oxidation of ethanol to acetic acid, CH3CH2OH() + O2(g) -> CH3COOH() + H2O()given the thermochemical equations below. 2 CH3CH2OH() + O2(g) -> 2 CH3CHO() + 2 H 2O() H° = -400.8 kJ/mol-rxn2 CH3CHO() + O2(g) -> 2 CH3COOH() H° = -584.4 kJ/mol-rxn
A cylinder with a moveable piston contains 0.84 mol of gas and has a volume of 328 mL. What will its volume be if an additional 0.27 mol of gas is added to the cylinder? (Assume constant temperature and pressure.)
If you look at a reaction for an esterification reaction, you cannot tell where the oxygen comes from (acid or alcohol). Draw the mechanism of this reaction, and devise an experiment using the mechanism and O18 (O18 isotope) to help prove unequivo..
