Cohesion is seen in a droplet of water, when water is "pulled" by other water molecules up the stem of a plant by sticking to one another and when water has a high surface tension. All of these are due to the bonds between the molecules of water. What is cohesion in simple terms?

Examples of Chemical Bonds The two main types of bonds arecovalent bondsandionic bonds. Covalent bonding is where atoms share electrons more or less equally between each other. In an ionic bond, an electron from one atom spends more time associated with the nucleus and electron orbitals of the...
summer, producing shallow ponds. During this time, lichens and flowering plants typically grow. Because of the ice that covers the land in the tundra, this type of ecosystem is important in regulating the earth’s temperature. It also serves as a water reservoir (in the form of ice or ...
The energy goes into breaking hydrogen bonds. It takes a lot of energy to make water increase in temperature. The reverse is true too; it takes a lot of energy to lower the temperature of water. Basically, water really doesn't want to change temperature. We're pretty lucky to be made ...
or triple. A single bond (-) is when the atoms share two electrons. It is usually a sigma (σ) bond. For example, a water molecule has two hydrogen atoms and a central oxygen atom that are held together by two single covalent bonds. Each hydrogen atom shares a pair of electrons with...
Examples of Molecules with Polar Covalent Bonds Water (H2O) is a polar bonded molecule. The electronegativity value of oxygen is 3.44, while the electronegativity of hydrogen is 2.20. The inequality in electron distribution accounts for the bent shape of the molecule. The oxygen "side" of the ...
Examples of Revenue Bonds: Let’s explore some real-world examples of revenue bonds: The New York City Transportation Revenue Bonds, issued to fund the construction and maintenance of bridges, tunnels, and roads in the city. The California State University Revenue Bonds, used to finance the expa...
Molecules such as water or a carbohydrate are formed through chemical reactions and held together by chemical bonds. A chemical reaction is a process by which one or more reactants are converted into one or more products. In this process, chemical bonds are either broken or formed. Reactants...
Chemical reactions occur when the bonds between atoms in a substance break and reform to produce new compounds. The formation of new substances via chemical reactions is dependent upon the ability of molecules to break down into their constituent atoms and ions. ...
