using heat of formation.
Fuel cells can be powered by the reaction between formic acid and oxygen as following HCOOH + 12 02 → CO2 + H2O As formic acid and oxygen react together inside the fuel cell, it produced both electrical power and heat. While there is no shaft work produced by the fuel cells, this electrical power produced by the fuel cells can be considered as the shaft work term when you perform the energy balance. A fuel...

TRODUCTION Chemical processes occur spontaneously when they lower the free energy of the system. The free energy at constant temperature and ressure is the Gibbs free energy, AG, which is defined as follows: AG = AH - TAS where AG is the change in free energy of the system, AH is the change in enthalpy of the system and AS is the change in entropy of the system AG, the change in free energy, must be less than zero for...

.1 Imagine a small fish that lives in a rocky coastal area. The fish is a light color almost white but the rocks in which it hides are dark black and grey. Describe how this population of fish could change to be a darker color (to be more camouflaged in the rocks) through the process of natural selection. Include a list of steps for this fish that would have to take place for natural selection to work. 2. Answer each...
