Consider the following reaction, in which two electrons are transferred from cytochrome-c (reducted): 2 cyt-c[fe2+] + pyruvate + 2h+ → 2 cyt-c[fe3+] + lactate calculate the standard gibbs free-energy change for the reaction at ph 7 and 25oc. [express your answer in units of kj/mol]

Select the correct answer. which statement is true about a polarized object? o a. it gains electrons and becomes negatively charged. ob. it gains protons and becomes positively charged. oc. the number of positive and negative charges can be the same. od. it has to be a metal. o e. there is no change in the distribution of the charge in the object. reset next what

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same

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.
