Definition of chemical properties：chemical property is the nature of matter in chemical change. Such as the chemical connectivity of the substances categories of acid and alkaline, oxidation, reduction, thermal stability and other characteristics. The chemical properties and chemical change is inherent in any material properties, such as oxygen in the combustion of substances, with its chemical properties; while the oxygen can react with water to produce hydrogen, its chemical properties. Any material is different with other substances through the chemical properties and chemical changes, and the chemical properties of the material are relatively static and chemical change is the relative movement of the material.
The basic definition of chemical properties：The nature of substances in the chemical changes when they show is called chemical property Such as: flammability, stability, acid and alkali, oxidation, reduction, combustion, corrosive, toxic, dehydration etc.. It involves a change in the chemical composition of the material molecules (or crystals).
After mastering the definition of chemical properties,we need to understand its judgment method
.Such as flammability, stability, stability, thermal stability, acid and alkali, oxidation, reduction, combustion, complex, toxic, corrosive, metal, non-metallic substances react with some present phenomenon. The chemical nature of the substance can be found by means of a chemical reaction of the substance.
According to the definition of chemical properties to distinguish the change.
Chemical properties: the nature of matter in chemical change is called chemical properties.
Chemical change: when the material is changed, it is called a new substance, which is called chemical change.
Should pay attention to the differences between chemical and chemical properties, change is a process, the nature of the category of capacity, such as candle burning is the reaction of paraffin and oxygen, water and carbon dioxide, chemical changes; this change to prove that candles can burn, it is the chemical nature of paraffin. The chemical properties of matter are determined by its structure, and the structure of matter can be reflected by its chemical properties. The use of matter is determined by its nature. Differences in chemical and physical properties of the two concepts.
