Figure 14.42 presents three chemical reactions. Which of the reactions are homogeneous and which are heterogeneous?
S7P2A21 (Identity - Physical Properties)
Pj Problem of Interest is of type identity (physical properties). There is a grouping component to this problem (homogeneous reactions and heteregeneous reactions). However, the problem of interest has to do with the definition of homogeneous and heterogeneous reactions, that is, the characteristics that enables the identification of the reactions. Definition problems are identity problems. It is in this sense that the Pj Problem of Interest is of type identity.
A homogeneous reaction is a single phase reaction, that is, reactants and products exist in the same phase.
A heterogeneous reaction is a reaction involving two or more phases.
Nitrogen and Oxygen react reversibly to form Nitric Oxide (formation of nitric oxide in the electric arc) .
Both reactants and product are gases. So reaction is single phase and therefore homogeneous.
Chemical reaction (2):
Crystalline potassium perchlorate react with crystalline carbon to form crystalline potassium chloride and gaseous carbon dioxide.
There are two phases in this reaction (solid and gas). So, reaction is heterogeneous.
Chemical reaction (3):
Crystalline zinc in acid reacts with hydrogen ion to form zinc ion and hydrogen gas.
There are three phases in this reaction (solid, liquid and gas). So, reaction is heterogeneous.
The point . is a mathematical abstraction. It has negligible size and a great sense of position. Consequently, it is front and center in abstract existential reasoning.

The Universe is composed of matter and radiant energy. Matter is any kind of mass-energy that moves with velocities less than the velocity of light. Radiant energy is any kind of mass-energy that moves with the velocity of light.
