Why do the properties change when a compound forms?

Why do the properties change when a compound forms?

A compound always has the same elements in the same proportions. The properties of compounds are different from the properties of the elements that form them sometimes very different. That s because elements in a compound combine and become an entirely different substance with its own unique properties.

What would happen to the properties of a monomer as it became a polymer?

During polymerization, chemical groups are lost from the monomers so that they may join together. In the case of biopolymers of carbohydrates, this is a dehydration reaction in which water is formed.

What chemical reaction is used to make polymers?

polymerization
The chemical reaction in which high molecular mass molecules are formed from monomers is known as polymerization. There are two basic types of polymerization, chain-reaction (or addition) and step-reaction (or condensation) polymerization.

Do chemical properties change when a compound is formed?

Chemical change results in one or more substances of entirely different composition from the original substances. The elements and/or compounds at the start of the reaction are rearranged into new product compounds or elements.

What are changes of matter?

There are two types of change in matter: physical change and chemical change. Many physical changes are reversible (such as heating and cooling), whereas chemical changes are often irreversible or only reversible with an additional chemical change.

What happens to the properties of the element which forms a compound?

Answer: When elements combine to form compounds, their individual properties are lost. In comparison, elements retain some (or many) of their property when they are mixed to form a mixture.

How would you modify a polymer and this affect its properties?

Overall, the main ways to change and tune the properties of a polymer include changing the length of the polymer chains, creating branched chains from linear polymer chains, crosslinking the polymer chains and adding plasticizers into the polymer.

What factors affect polymer properties?

Polymer properties depend on the chemicals that the polymer is made from and polymerization conditions that ultimately set molecular architecture: chemical linkage type, chain length, and the nature of the end groups. The type of the monomer-repeat unit that forms a polymer has a strong effect on polymer properties.

What is a polymer and what type of chemical reaction produces a polymer?

polymerization, any process in which relatively small molecules, called monomers, combine chemically to produce a very large chainlike or network molecule, called a polymer. The monomer molecules may be all alike, or they may represent two, three, or more different compounds.

What is polymer reaction?

In polymer chemistry, polymerization (American English), or polymerisation (British English), is a process of reacting monomer molecules together in a chemical reaction to form polymer chains or three-dimensional networks. There are many forms of polymerization and different systems exist to categorize them.

What is chemical change properties?

The change of one type of matter into another type (or the inability to change) is a chemical property. Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion.

What properties change in a chemical reaction?

The signs of chemical change include changes in color, temperature, the production of light, changes in odor, and the formation of gases.
