Expert Answers

Substances can be classified as either element, compound or mixtures. Elements are the purest form of substances, since they contain only one type of atoms. Examples of elements include, iron, silver, gold, copper, etc. Compounds are formed when two or more elements combine in a fixed ratio, in such a manner that the final product has different properties than its individual components. An example of a compound is water (H2O) which is formed by combination of hydrogen and oxygen in a fixed 2:1 ratio. Mixtures are formed by a combination of two or more elements or compounds in a non-specific ratio. 

Wood is a mixture and consists of various components such as lignin, cellulose, etc. The relative concentration of these components is not fixed and hence wood can be classified as a mixture. In fact, wood can be termed a heterogeneous mixture.

Is wood a compound, element, or mixture?   

A material can be classified as either an element, compound or mixture. An element is composed of identical atoms bound together. A compound is composed of two or more elements in a certain ratio and can be broken into individual elements by breaking the bonds between them. Mixtures contain two or more elements in non-specific ratios and can be easily separated into individual elements.

Wood is composed of a number of compounds such as lignin, cellulose, water, hemicellulose, etc. The relative composition of wood varies from plant to plant. Unlike a compound, wood does not have a fixed chemical formula. Hence, wood is a mixture. In fact, wood is a heterogeneous mixture, since these constituent compounds are mixed unevenly in a given wood sample.

Is wood a compound, mixture, or element?

Any material can be classified as either an element, a compound or a mixture, depending on its properties. An element is composed of identical atoms and cannot be further divided. An example is copper. A block of copper will contain only atoms of copper and any division of this block will still yield copper. A compound is composed of elements in a certain fixed ratio and has different properties than its constituent elements. An example is carbon dioxide (CO2), which is made up of oxygen and carbon in a 2:1 ratio. A mixture is composed of two or more elements or compounds in a non-fixed ratio and can be divided into individual constituents. An example is trail mix, which can be easily separated into constituents. 

Wood is an example of a mixture. It contains cellulose, lignin and hemicellulose, in a variable ratio. Wood can actually be classified as a heterogeneous mixture, since the constituents are distributed non-uniformly.

Is wood an element, a compound, or a mixture?

An element is a pure substance that cannot be further subdivided into purer or simpler forms. A compound is made up of two or more different elements and can thus be divided into simpler forms (individual elements).  A compound contains these elements in a fixed ratio and has properties that are different from each constituent element. A mixture is made up of different elements or compounds, where each constituent retains its original properties. A mixture can also be separated into individual constituent by physical means. Wood is composed on a number of compounds, including water, cellulose, lignin and hemicellulose. The relative concentration of each of these varies from plant to plant. All these compounds are in turn made up of elements, such as carbon, hydrogen and oxygen. In essence, wood is a heterogeneous mixture.
