What is a compound? Properties of compounds differ from those of their elements. For example, salt is made up of two elements: chlorine, which is poisonous; and sodium, which reacts explosively with water. See related question below for the distinction between a compound and a molecule. it is made up of two or more different elements. e.g. carbon dioxide = CO2 = 1carbon + 2oxygen atoms.

In chemistry, what does w/w mean? Best Answer: w/w- an abbreviation for by weight, used in chemistry and pharmacology to describe the concentration of a substance in a mixture or solution. Properly speaking, 2% w/w means that the mass of the substance is 2% of the total mass of the solution or mixture. The metric symbol g/g has the same meaning as w/w.

- A compound is a substance made from two or more elements that have reacted chemically with each other. Remember this definition as you might need it in the exam! A compound is a completely new material that will often have totally different properties from the elements that made it. For example The element sodium is a highly reactive metal. The element chlorine is a yellow-green poisonous gas (non-metal). When the two react together they form a compound called sodium chloride.

Rotenone Rotenone is an odorless, colorless, crystalline ketonic chemical compound used as a broad-spectrum insecticide, piscicide, and pesticide. It occurs naturally in the seeds and stems of several plants, such as the jicama vine plant, and the roots of several members of Fabaceae.otenone works by interfering with the electron transport chain in mitochondria. To be specific, it inhibits the transfer of electrons from iron-sulfur centers in complex I to ubiquinone.

Difference Between Compound and Mixture Chemical compound. A chemical compound is a pure material made out of a combination of two or more chemical elements that have been bonded through chemical procedures. Unlike an element, which is quite basic and simple because it is made up of only an atom and electrons, a chemical compound is more complex.

Chemical compound A chemical compound is a chemical substance consisting of two or more different chemically bonded chemical elements, with a fixed ratio determining the composition. The ratio of each element is usually expressed by chemical formula. For example, water (H2O) is a compound consisting of two hydrogen atoms bonded to an oxygen atom. The atoms within a compound can be held together by a variety of interactions, ranging from covalent bonds to electrostatic forces in ionic bonds. A continuum of bond polarities exist between the purely covalent bond (as in H2) and ionic bonds. For example H2O is held together by polar covalent bonds. Sodium chloride is an example of an ionic compound.

Definition of Compound A compound is a substance formed when two or more chemical elements are chemically bonded together. Two types of chemical bonds common in compounds are covalent bonds and ionic bonds.The elements in any compound are always present in fixed ratios.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.Example 2: Pure table salt is a compound made from two elements-sodium and chlorine.he elements in any compound are always present in fixed ratios.

What is the difference between a compound and a molecule? A compound is a molecule that contains at least two different elements. All compounds are molecules but not all molecules are compounds. Molecular hydrogen (H 2), molecular oxygen (O 2) and molecular nitrogen (N 2) are not compounds because each is composed of a single element.

Water activity Water activity or a w is the partial vapor pressure of water in a substance divided by the standard state partial vapor pressure of water. In the field of food science, the standard state is most often defined as the partial vapor pressure of pure water at the same temperature.ater migrates from areas of high a w to areas of low a w. For example, if honey (a w ≈ 0.6) is exposed to humid air (a w ≈ 0.7), the honey absorbs water from the air. If salami (a w ≈ 0.87) is exposed to dry air (a w ≈ 0.5), the salami dries out, which could preserve it or spoil it.

Is Water a Compound or an Element? Here's the answer to the question and the explanation for it. Answer: Yes, water is a compound. A compound forms whenever two or more atoms form chemical bonds with each other. The chemical formula for water is H 2 O, which means each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms. Thus, water is a compound. It's also a molecule, which is any chemical species formed by two or more atoms chemically bonded to each other. The terms molecule and compound mean the same thing and can be used interchangeably.
