Answer:
Partial molar volumes help to assess the influence of pressure on phase equilibria or reaction equilibria. The prediction of partial molar volumes or excess volumes is a sharp test for theories of the fluid state.
On the other hand, the interpretation of partial molar volumes or excess volumes is usually difficult, if not impossible. Many mixtures exhibit positive and negative excess volumes, depending on composition, temperature, and pressure. Speculations why some mixture exhibits positive or negative excess volumina are futile, particularly if they are based on measurements at ambient pressure and temperature only.
Explanation:
Answer:
Carbon dioxide can be collected over water. Carbon dioxide is slightly soluble in water and denser than air, so another way to collect it is in a dry, upright gas jar.
Explanation:
The answer is B.Desertification
Answer: Ions in ionic compounds are arranged in a repeating pattern of alternating charges, whereas metals consist of fixed cations surrounded by a sea of mobile, or delocalized, electrons. ... Delocalized electrons can move through the solid to conduct an electric current.
