Potassium hexafluoroantimonate can be prepared by reacting potassium pyroantimonate K 2 H 2 Sb 2 O 7 with hydrogen fluoride or by treating the product of the reaction of a mixture of solid antimony(III) oxide and potassium hydroxide with hydrogen peroxide solution (30%) with hydrochloric acid (48%).
Exothermic refers to a transformation in which a closed system releases energy (heat) to the surroundings, expressed by > When the transformation occurs at constant pressure and without exchange of electrical energy, heat Q is equal to the enthalpy change, i.e.
In technical terms, the reaction zone (chemical combustion) is a self-driven shock wave where the reaction zone and the shock are coincident, and the chemical reaction is initiated by the compressive heating caused by the shock wave. The process is similar to ignition in a Diesel engine, but much more sudden and violent.
A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. [1] When chemical reactions occur, the atoms are rearranged and the reaction is accompanied by an energy change as new products are generated.
