Define why trans-p-anisalacetophenone would be expected to be additional stable than the corresponding cis isomer.
Assuming that the loss of ability to recall Chem 401 material is a first-order process with a half-life of 55 days for the traditional (talking head lecture) and a C of 305 days for the active approach,
suppose 45.0g of water at 85 C is added to 105.0 g of ice at 0 C. The molar heat of fusion of water is 6.01 kJ/mol, and teh specific heat if water is 4.18 J/g C. on this basis of these data (a) what will be the final temperature of the mixture and..
