Complete the mechanism for the electrophilic addition wtien the alkene is treated with water in acid. b. complete the structure of the carbocation a. use curved arrows to show the attack on the intermediate by adding the missing positive electrophilic hydrogen by the alkene. charge. use a curved arrow to show the attack of the water on the carbocation.

Iwill give extra points to who gets this right

How many protons, electrons, and neutrons are in each of the following isotopes? a. zirconium-90 b. palladium-108 c. bromine-81 d. antimony-123

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. despite its name, silica gel is a solid. it is a chemically inert, highly porous, amorphous form of sio2. because water vapor readily adsorbs onto the surface of silica gel, it acts as a desiccant. despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided you should be able to make an educated guess about the thermodynamic characteristics of the process. predict the signs for δg, δh, and δs for the adsorption of water.
