Sucrose is a polar molecule because the bond between the oxygen and the hydrogen atoms gives the oxygen a slight negative charge and the hydrogen a slight positive charge. The negative and positive areas attract the polar water molecules, and this allows the sucrose to dissolve in water.
A polar molecule can be identified because it will always have a partial positive and partial negative charge as a result of the polar bonds that are arranged asymmetrically. Water is another example of a polar molecule. In contrast, a nonpolar molecule is one where there is an equal sharing of electrons between the two atoms of a diatomic molecule.Learn More
Water is formed when oxygen and hydrogen atoms combine, and it takes a total of three atoms to make a water molecule. Two of the atoms are hydrogen and the last atom is oxygen, hence the chemical formula H2O.Full Answer >
There are several different ways to create oxygen, but the easiest is by passing an electric current through water to separate the hydrogen atoms from the oxygen atoms. This process is called electrolysis, and is one of the primary ways in which space stations create breathable air for the astronauts. Electrolysis is a relatively easy procedure, which is why it is a common technique for extracting oxygen form water.Full Answer >
Hydrogen does not exist in pure form in nature and instead is produced from a primary energy source, such as fossil fuels, solar, geothermal and wind energy, or extracted from other elements such as oxygen. Hydrogen is found embedded in, or coexisting with, other elements on Earth, in water and in the atmosphere. Hydrogen is quite abundant but is often difficult to extract and separate from surrounding minerals and elements.Full Answer >
Two individual hydrogen atoms can be bonded together by a covalent bond. Since each hydrogen atom contains one electron, they can evenly share their electrons and form a strong covalent bond.Full Answer >
