Tetrachloromethane

In the carbon tetrachloride molecule, four chlorine atoms are positioned symmetrically as corners in a tetrahedral configuration joined to a central carbon atom by single covalent bonds. Because of this symmetric geometry, CCl4 is non-polar. Methane gas has the same structure, making carbon tetrachloride a halomethane.

Phosphorus pentafluoride is a phosphorus halide.

CO is carbon monoxide, and it is a compound. Carbon monoxide is made of atoms of carbon bonded to atoms of oxygen. It is made up of 1 atom of carbon and 1 atom of oxygen. Whereas, Co is Cobalt, which is an element.

A compound is the substances that are formed by combining two are more chemical elements. A mixture is a substance created from two or more matter that can be separate with the help of physical methods. Compound substances are always homogeneous in nature.

Compounds can be broken down into smaller compounds, or their basic elements, by chemical change. Electrolysis is a chemical change produced by sending an electric current through a compound. Using electrolysis, we can break down water into its elements, hydrogen and oxygen.

Compounds differ from mixtures in that the elements in a compound are held together by chemical bonds and cannot be separated by differences in their physical properties. Compounds can be separated into their components only by chemical change.

Distillation works best for purifying compounds that are liquids at room temperature. Solids are more likely to be purified by recrystallization, which takes advantage of differences in the solubility of various components of a mixture in different solvents.

Distillation is used to separate liquids from nonvolatile solids, as in the separation of alcoholic liquors from fermented materials, or in the separation of two or more liquids having different boiling points, as in the separation of gasoline, kerosene, and lubricating oil from crude oil.

These can be separated by distillation in a laboratory using a burner placed under a beaker containing the salt water. Distillation may seem like a chemical process, but in fact it is purely physical, because the composition of neither compound—salt or water—has been changed.

Scientific definitions for compound compound. [ kŏm′pound′ ] A substance consisting of atoms or ions of two or more different elements in definite proportions joined by chemical bonds into a molecule. The elements cannot be separated by physical means.

Compound means to combine; a compound is a combination or mixture of two or more things. Compound has several specialized uses. In linguistics, a compound is a word that consists of two or more independent words. In chemistry, a compound is a substance created when atoms from chemical elements join together.

A compound is a substance formed when two or more chemical elements are chemically bonded together. Example 1: Pure water is a compound made from two elements – hydrogen and oxygen. The ratio of hydrogen to oxygen in water is always 2:1. Each molecule of water contains two hydrogen atoms bonded to a single oxygen atom.

A compound sentence is made up of two independent clauses joined by a coordinating conjunction (for, and, nor, but, or, yet, or so) and a comma or by a semicolon alone. Example: The pirate captain lost her treasure map, but she still found the buried treasure.
