Detailed explanation-1: -Chemical properties are very useful in identifying substances. However, unlike physical properties, chemical properties can only be observed as the substance is in the process of being changed into a different substance.

Detailed explanation-2: -A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products. Substances are either chemical elements or compounds.

Detailed explanation-3: -Chemical property of a substance tells about how it will react with other substances. It also predicts how oxidation number increases/decreases of a substance during the reaction. It shows the mechanism of the chemical reaction. Toxicity, flammability, and reactivity of a substance come under chemical properties.

Detailed explanation-4: -This is called a chemical reaction. Gas may form, heat may be produced, and color may change. These types of changes indicate that a chemical reaction has occurred. Also explain that some substances when mixed together produce no chemical reaction.

Detailed explanation-5: -A chemical property is a characteristic of a particular substance that can be observed in a chemical reaction. Some major chemical properties include flammability, toxicity, heat of combustion, pH value, rate of radioactive decay, and chemical stability.
