Why do some chemical reactions occur whereas others do not?
Underpinning the occurrence of every chemical reaction is the driving force to achieve stability, i.e. the second law of thermodynamics. This is usually done by-elections in the outer shell orbiting an atom that interacts with other electrons orbiting other atoms to achieve stability through completing the other atom's valence shell and falling into an energy well that binds the atoms together. The only way to undo this binding is to provide enough energy to raise the bonding electrons out from the energy well or to present another combination of electrons from another atom where the electrons may fall further into an energy well.
What is the fundamental difference between algebra and calculus.
Algebra deals with discrete equations and functions and applies this logic to fixed problems. Calculus on the other hand allows the ability to predict how things change with space or time. This is invaluable in solving real-world problems as most processes deal with change in respect to other variables once you begin to model processes in more detail.

When optimizing a chemical plant, what is the best strategy to achieve the most effect results?
Without setting up a large analysis, you can identify whether you are rejecting excessive raw material in your product stream and install some form of the material separator to recycle the wasted raw material back to your feed stream. In addition, if there are different streams that need to be heated or cooled, the streams may be used to heat/cool the other through a separate heat exchanger to avoid the need for external heating or cooling utilities.
