A hydrated compound of chromium (III) nitrate is found to be 40.5% water by mass. What is the empirical formula for the hydrate, Cr(NO3)2 * x H2O

According to the vsepr theory what is the shape of a molecule that has a central atom valence three other items with no lone pairs of electrons

Hey guys so i need to know what is _nh3+> nh4oh ~chemistry~

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.
