CHEMICAL REACTIONS OBJECTIVES 1. To study reactions
... When two ionic solutions are mixed and there is not an ion combination that is insoluble or gaseous, no reaction will be observed. For example, no reaction occurs between NaCl and KNO3 because all ionic combinations are soluble compounds. Part II. Exothermic and endothermic reactions Reactions that ...

... e. Reaction occurs through homolytic fission to form a free radical (HL only) i. Free radical is a element or molecule with an unpaired electron ii. Homolytic fission vs Heterolytic fission: 1. Fission means splitting apart 2. Homolytic means the bond is split in half – each side takes 1 electron an ...

Cracking (chemistry)
In petroleum geology and chemistry, cracking is the process whereby complex organic molecules such as kerogens or heavy hydrocarbons are broken down into simpler molecules such as light hydrocarbons, by the breaking of carbon-carbon bonds in the precursors. The rate of cracking and the end products are strongly dependent on the temperature and presence of catalysts. Cracking is the breakdown of a large alkane into smaller, more useful alkanes and alkenes. Simply put, hydrocarbon cracking is the process of breaking a long-chain of hydrocarbons into short ones. More loosely, outside the field of petroleum chemistry, the term ""cracking"" is used to describe any type of splitting of molecules under the influence of heat, catalysts and solvents, such as in processes of destructive distillation or pyrolysis. Fluid catalytic cracking produces a high yield of petrol and LPG, while hydrocracking is a major source of jet fuel, Diesel fuel, naphtha, and again yields LPG.
