Q:

What are true solutions in chemistry?

A:

Quick Answer

True solutions, or homogenous solutions, exist as air, oxygen and brass, and are mixtures that contain two or more substances. Homogenous solutions can be broken down into separate substances, and the substances used to form them vary according to the amount of each that is used to create the complete solution.

Full Answer

Homogenous solutions exist in several different states, but are most commonly found as liquids. Some solutions are made of gases and solids as well, however; air is one of the most prevalent examples of a gaseous homogenous solution. Air is comprised of the elements of oxygen and nitrogen, and contains trivial amounts of other gases. Brass is an example of a solid homogenous solution, and is made of zinc and copper.

    What is standard enthalpy change?

    A:

    Standard enthalpy change is the energy exchange that occurs when the surroundings are at standard conditions, which includes constant atmospheric pressure, a room temperature of 25°C, normal physical states for all substances involved, and a concentration of 1 mol per liter for solutions. The types of standard enthalpy changes are reaction, formation and combustion.

    What is an extinction coefficient?

    A:

    In chemistry and biology, the extinction coefficient can refer to the mass attenuation coefficient or the molar absorptivity, which both relate to calculations of how different substances absorb light wavelengths. In physics, the extinction coefficient relates to index of refraction and absorption and is based on intensity and electric field.
