A student builds three Class 1 levers. Lever A has an effort arm of 2 m and a load arm of 3 m. Lever B has an effort arm of 1.5 m and a load arm of 3.5 m. Lever C has an effort arm of 4 m and a load arm of 1 m. Which lever has the largest mechanical advantage? Show your work.

Calculate the number of moles of ethane in 100 grams

The missing component to the table to the right or indicated with orange letters complete the table by filling in the corresponding numbers or symbols

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.
