Ahydrocarbon, containing only c and h, can react with excess oxygen gas to produce carbon dioxide and water. the result of the complete reaction of an unknown hydrocarbon with formula cxhy is shown in the table. what is the formula of the hydrocarbon?

Identify arrows pointing to bonding electrons. done h-0-0-h ) intro

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.

To calculate percent by mass, use the equation below: calculate the percent by mass of each element. %n = % %h = % %o = %
