what are the chemical properties of wood?
243835
A chemical property is a characteristic that can only be seen when the material changes and a new material is formed. Examples of chemical properties are ability to burn, ability to rust and ability to sour. So a chemical property of wood is its ability to burn. When it burns, it gets hot and changes to ash.

Chemical properties that are important in characterizing materials include composition, structure, molecular weight, boiling and melting points, vapor pressure, octanol-water partition coefficient, water-solubility, reactivity, and stability.

Wood is obtained from trees. Trees are not an element. They have cells not molecules or atoms. If there are no atoms then there would be no electrons.

Properties. The physical properties of organic compounds typically of interest include both quantitative and qualitative features. Quantitative information includes a melting point, boiling point, and index of refraction. Qualitative properties include odor, consistency, solubility, and color.

4. Characteristic Properties of Matter—The Key Ideas The physical properties of matter include color, odor, density, solubility, melting point, boiling point, and electrical conductivity. These are properties that can be observed without chemically changing the substance. 5.

Summary. Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Reactivity is the ability of matter to react chemically with other substances.

Chemical properties include things like reactivity to oxygen, flammability, and ability to hold on to electrons during a chemical reaction. The periodic table is a table that organizes elements based on their atomic number and properties.

The important chemical properties of organic compounds are Combustion: Carbon in all its allotropic forms burns in air or oxygen to give carbon dioxide and releases energy in the form of heat and light. Most carbon compound also release a large amount of heat and light on burning.

The chemical composition of wood varies from species to species, but is approximately 50% carbon, 42% oxygen, 6% hydrogen, 1% nitrogen, and 1% other elements (mainly calcium, potassium, sodium, magnesium, iron, and manganese) by weight.

Classifying how a substance looks and how it smells does not require changing its composition. Thus, nitrogen's lack of color and odor are physical properties. Some other examples of physical properties are viscosity, density, melting point, volume, and ductility.
