Suppose you put some water in your ice-cube tray and then place the tray in the freezer. Consider a single ice cube that starts out as 31.0 ml of liquid water at 20.0°C. To determine the energy that must be removed from the water to convert it to an ice cube, we must consider the process in three stages. For stage 1, determine how much energy must be removed from the water to cool it to water at 0.00°C Enter...

Thank you! A ketone is added to acidic water (i.e., water that has some HCl added to it), and, to some extent, a hydrate is formed. What are the mechanistic steps for this reaction? To answer, use the following numbering scheme: 1-pt., 2 Nu attack, 3-Loss of L, 4 = SN2, 5-no reaction. For example, if you felt that two proton transfers were followed by loss of a leaving group, you would write: 1,1,3 or 1, 1, 3 A secondary...
