This is an attractive interaction between a hydrogen atom from a molecule or a molecular fragment X-H in which X is more electronegative than H, and an atom or a group of atoms in the same or a different molecul
The most widely known example of a solvent is water. Solvents are classified as being either polar or nonpolar. Solvents can also either be polar aprotic or polar protic. Other examples of solvents include toluene, benzene, acetone, and others....
Water is “wetting”, while mercury is non-wetting. Water is polar and attracted to substances. This is why water creeps up the walls of the container, and mercury does not. We can easily see the difference when the liquids are placed in capillaries and and observe the curvatures....
planets, asteroids, comets and highly rarefied intergalactic gas. But, if this is so, then accelerated expansion is contrary to the law of gravity, which says that bodies are attracted to each other. Gravitational forces tend to slow down the expansion of the universe, but cannot accelerate ...

Abnormally bright radar reflections below the Martian south polar layered deposit were originally interpreted as evidence of subglacial liquid water. However, unlike on Earth, conditions beneath the Martian ice are too cold to create or maintain meltwater. In this work, we use radar reflectivity ...
Explain why pregnancy is referred to as a diabetogenic condition. What makes an OH group stretch broad on an IR spectrum? Explain the difference between K_P and K_c. When is each used? Is basin of water equivalent to basin of ice, why or why not? Explain in your own words. ...
Explain why, when a thermometer is placed in hot water, the column of mercury first descends slightly and then rises. (a) Briefly cite the main differences between ionic, covalent, and metallic bonding. (b) State the Pauli ex...
In terms of structure and bonding explain why water is a liquid and hydrogen sulfide is a gas at room temperature?Temperature and Pressure Standards:Room temperature is a standard temperature used in chemistry and is equal to 25 Celsius degrees. It is ...
