In this article, the effect of the water type and chemistry on the swelling behaviour of the clays was investigated by testing the clay samples with eight different types of water collected from the sea, river, lake and different rock formations. The main result of this research was that the...

Presence of water molecule is evident in its structure indicating that the title compound is in hydrated form. The single crystal X-ray diffraction data corresponding to hydrogen bonding reveals the hydrogen-bond strength sequence as: N─H• • •N > O─H• • •O > N─H• ...

Honing in on nuclei "spin" When broken down, water molecules are made up of a single oxygen atom bonded to a pair of hydrogen atoms. This chemical formula is more commonly known as H2O and is generally assumed to be an all-inclusive term. However, when analysing the "spin" of the nucl...

In adecomposition reaction, a compound is broken into smaller chemical species. AB → A + B The electrolysis of water into oxygen andhydrogen gasis an example of a decomposition reaction: 2 H2O → 2 H2+ O2 Single Displacement or Substitution Reaction ...
A chemical product is what is produced in a biochemical reaction. For example, a common biochemical reaction in our cells involves the breakdown of hydrogen peroxide into water and oxygen. This reaction can be written as: $$2H_2O_2⇒ 2H_2O + O_2 $$ In this example, the reactant is...
Naturalists did concede that environmental factors may have played a role in the differences among species, but it was well understood that each individual species, with all its uniqueness, was the work of a creator. Darwin, however, thought differently. Darwin's theory of Natural Selection ...
