Detailed explanation-1: -Chemical properties describe the characteristic ability of a substance to react to form new substances; they include its flammability and susceptibility to corrosion. All samples of a pure substance have the same chemical and physical properties.

Detailed explanation-2: -A chemical property is a characteristic of a substance that indicates whether it can undergo a change that results in a new substance.

Detailed explanation-3: -In a physical change the nature of the substance, the particles of which it is composed and the numbers of particles remain unchanged. In a chemical change the properties of the new substances are different from the original, the particles are different and the number of particles can change.

Detailed explanation-4: -A property of matter that describes a substance’s ability to participate in chemical reactions is a chemical property. When wood is burned, smoke and ash are created. These have very different properties than the wood. Two types of chemical properties are flammability and reactivity.

Detailed explanation-5: -In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition.
