When the oxidation number of an element decreases over the course of a reaction, that element has beenwhich of the following chemical reactions is an oxidation-reduction reaction? cuso4 + bacl2 yields baso4 + cucl2 agno3 + nacl yields agcl + nano3 pb(no3)2 + 2nacl yields pbcl2 + 2nano3 zn + h2so4 yields znso4 + h2

Which is mostly likely why many scientists reject the cold fusion theory

Consider the reaction: n2(g) + o2(g) ? 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?

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.
