Water contains two hydrogen and one oxygen atom. It is bent in the shape of an "L". The position of the hydrogen allows the hydrogen to interact with other highly electronegative atoms in other molecules. Oxygen is a highly electronegative atom. The hydrogen forms hydrogen bonds with other water molecules' oxygen atom. This occurs throughout a solution of water. A tremendous amount of heat (energy) has to be applied to break these bonds for water to change from one state to another. This is why it has a high boiling point when you try to go from liquid to gas.
It is possible to explain data structure in layman's terms. Simply put, in computer terms, a data structure is a commonly used method of data organization.
There is no difference in terms of molecular structure but the phase it is in, can be varied in ammonium trihydride. Gas for ammonia gas.

copper is an element, so in terms of molecular structure, it extremely simple(Cu or Cu2) In terms of atomic structure and electron/proton/neutron configuration it is obviously more complex.It contains 29 protons and electrons, an 35 neutrons. Finally, in terms of crystal structure, its pretty simple because it is face-centered cubic
This site can explain everything pertaining to the strengths of ceramics, first an excerpt then the site:Abstract The key features of the processes underlying the failure of ceramics are considered for a wide temperature range. The brittleness and high-temperature plasticity of ceramics are correlated with their crystal chemistry. The general issues related to the strength of ceramics are treated in terms of synergetics, which deals with the spatiotemporal ordering and self-organization in nonequilibrium systems. The strength of ceramics is shown to be governed by its structure on different scales-from atomic to macroscopic. The conclusion is drawn that, in the strict sense, strength is not a property of the material; rather it characterizes its quality.* http://www.springerlink.com/content/lf6yr4pjf5wmh425/
due to hydrogen bonding no of molecular rearrangement in the structure is more than viscoce in viscose hydrogen bonds break up is more in terms of molecular arrangement so wet strength of cotton is higher than viscose fibre rajarahul28@gmail.com
a chemical change destroys the old atoms and molecules to make completely new ones and a completely new substance.
Trigonal pyramidal (see wikipedia article "Trigonal pyramidal molecular geometry" for a picture. In terms of VSEPR it is an AX3E compound so the three N-H bonds and the lone pair are approximately tetrahedrel- but as the lone pair repels a little more the bond angle is less than 109.50 at 1080
