1. "You can't win" most be the 1. law of thermodynamics that states that energy can neither be created nor destroyed. It can only change forms. In other words you can’t get more energy out of the system than you put into it."You can't break even" most be the 2. law of thermodynamics that states that the entropy of an isolated system not in equilibrium will tend to increase over time, approaching a maximum value at equilibrium. Or as the following that more apeals to the sentence "any transfer of energy will result in some waste of energy." (unless you have 0 K in the system)
2. Chemical diffusion occurs in a presence of concentration (or chemical potential) gradient and it results in net transport of mass. This is the process described by the diffusion equation. This diffusion is always a non-equilibrium process, increases the system entropy, and brings the system closer to equilibrium
3. Molecules or ions tend to follow their own concentration gradient and diffuse into an adjoining region of fluid in which they are less concentrated
7. Catalase breaks down hydrogen peroxide in two steps. A hydrogen peroxide molecule is broken apart, with an iron ion in the catalase latching onto an oxygen molecule. The rest of the…
