A plough or plow (US; both / p l aÊ /) is a tool or farm implement used in farming for initial cultivation of soil in preparation for sowing seed or planting to loosen or turn the soil. Ploughs were traditionally drawn by working animals such as horses or cattle, but in modern times are drawn by tractors.
Nonpolar molecule. Definition. noun, plural: nonpolar molecules. A molecule with nonpolar bonds or with polar bonds but arranged symmetrically. Supplement. Polar bonds may occur in both polar and nonpolar molecules.However, the polar bonds in nonpolar molecules are arranged symmetrically causing dipoles to cancel out each other. As a result, nonpolar molecules have no net dipole.efinition. noun, plural: nonpolar molecules. A molecule with nonpolar bonds or with polar bonds but arranged symmetrically. Supplement. Polar bonds may occur in both polar and nonpolar molecules.
When there are no polar bonds in a molecule, there is no permanent charge difference between one part of the molecule and another, and the molecule is nonpolar. For example, the Cl2 molecule has no polar bonds because the electron charge is identical on both atoms.It is therefore a nonpolar molecule.None of the bonds in hydrocarbon molecules, such as hexane, C6H14, are significantly polar, so hydrocarbons are nonpolar molecular substances. A molecule can possess polar bonds and still be nonpolar.t is therefore a nonpolar molecule.
