Q:

Is sucrose polar or nonpolar?

A:

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.

  • Q:

    Is sucrose ionic or covalent?

    A:

    Sucrose is a covalent compound. Whether a compound is ionic or covalent depends on the relative attraction the compound's atoms have for electrons. Sucrose is composed of carbon, hydrogen and oxygen, all of which have similar enough attractions for electrons to form covalent bonds with each other.

  • Q:

    How do you make oxygen?

    A:

    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.

  • Q:

    Where does hydrogen come from?

    A:

    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.

  • Q:

    Is sucrose soluble in ethanol?

    A:

    Sucrose or sugar is only slightly soluble in ethanol. In fact, if the alcohol is cold, even less of the sucrose is going to dissolve. The sugar that does not dissolve within the ethanol settles at the bottom of the container.
