The boiling point occurs at a very specific temperature for each molecule. That is why it is often used to identify an unknown substance in qualitative chemistry. The reason that the boiling point is predictable is because it is controlled by thestrength of the bondsholding the atoms in the m...

The principle of solubility, "like dissolves like," emphasizes the importance of polarity in determining whether substances will mix. Polar molecules, such as water and ethanol, dissolve in each other due to their similar net dipoles. Understanding the polarity of various organic compounds...
Suppose you are given a sample of a homogeneous liquid. What would you do to determine whether it is a solution or a pure substance? Apart from boiling point of water, what are other test used to identify water from other colorless liquids? What labor...
The homogenous liquid mixture is characterized by the presence of an equal quantity of the sub-components. It can also de defined as the fixed ratio of solute to solvent in the solution. The particles will not be visible to the normal ...
NMR is commonly known as the main technique used for structural characterization of organic compounds, in elucidating the nature of functional groups in petroleum, distillates or synthetic fuels either by one or two-dimensional methods, as well as in the study of the chemical composition of these ...
Minimum conversion efficiency of about 14% was obtained for high-nitrogen fuels at high oxygen content and aromaticity, and low sulphur content and boiling point. Minimum conversion efficiency of about 26% was obtained for low-nitrogen fuel at high aromaticity, boiling point and sulphur content, ...

the smallest complete unit of an element is an atom. A large chunk of matter can consist of trillions of atoms of a single element, such as a pound of pure gold. More often, different elements combine to form compounds, such as hydrogen (H) and oxygen (O) combining to form wa...
