1.
Acetone
is a
carbonyl compound that is found in the atmosphere as a reactive gas. Acetone is
considered to be a volatile organic compound (VOC), which is emitted into the
atmosphere by industrial processes. Acetone has been linked to the formation of
ozone in the troposphere due to the fact that it is a source of free radicals.
2.
Acidification
This process happens when
compounds like ammonia, nitrogen oxides and sulphur dioxides are converted in a
chemical reaction into acidic substances. Most of the compounds are a direct
result of air pollution.
3.
Acid-pulse (dry
deposition)
deposit of powder - like
substance over the ground surface; especially effecting plant leaves; that when
contacted by water has a very low pH.
4.
Addition
reaction
A reaction in which two atoms
or groups of atoms are added to a molecule, one on each side of a double or
triple bond
5.
Antinodes

interference between two waves
6.
Backscattering
Process
by which up to 25% of radiant energy from the sun is reflected or scattered away from the surface by clouds.
Serves the greatest importance in the Atmospheric Heat Budget. Large errors in the assumed value of this
variable may have important effects on
computer models of the atmosphere.
7.
Bayer process

to obtain aluminum from bauxite
8.
Benzene
is
an aromatic hydrocarbon. It can be found in the air by several different ways
of transmission. It can be
produced for use with plastic or produced through the burning of fossil fuels.
9.
Binary compound
A compound consisting of two
elements; may be ionic or covalent.
10. Buffer solution

light.
14. Covalent

Formula
A formula that shows what elements are in a
compound and what it will become.
16. Distillation
A process for separating substances by
evaporating a liquid and recondensing its vapor.

Spreading of particles throughout a given
volume until they are distributed.
18. Diatomic
Molecule
Consists of 2 atoms of the same element in a
covalent compound.
19. Double
Displacement Reaction
Two elements replace another to make a
product.
20. Denature
There
are two common meanings for this in chemistry. First, it can refer to any
process used to make ethanol unfit for consumption (denatured alcohol). Second,
denaturing can mean breaking down the three-dimensional structure of a
molecule, such as a protein is denatured when exposed to heat.
21. Electrolyte
An electrolyte
ionic compound
that dissolves in water to produce ions, which can conduct electricity. Strong electrolytes completely dissociate in water,
while weak electrolytes only partially
dissociate or break apart in water.
22. Element

Positively
or negatively charged, covalently bonded group.
40.
Additivies
something that is added, as one substance to
another, to alter or improve the general quality or to counteract undesirable
properties
41. Affinity
Affinity is the tendency of a molecule to
associate with another. The affinity of a drug is its ability to bind to its
biological target (receptor, enzyme, transport system, etc.)
Tell me more about antinodes, please?
BalasHapusThese are the points that undergo the maximum displacement during each vibrational cycle of the standing wave. In a sense, these points are the opposite of nodes, and so they are called antinodes. Antinodes, on the other hand, are produced at locations where constructive interference occurs. For instance, if a crest of one wave meets a crest of a second wave, a point of large positive displacement results. Similarly, if a trough of one wave meets a trough of a second wave, a point of large negative displacement results. Antinodes are always vibrating back and forth between these points of large positive and large negative displacement; this is because during a complete cycle of vibration, a crest will meet a crest; and then one-half cycle later, a trough will meet a trough. Because antinodes are vibrating back and forth between a large positive and large negative displacement.
Hapusgive an example about diffusion in chemical reaction
BalasHapusoxygen can diffuse through cell membranes and if there is a higher concentration of oxygen outside the cell than inside, oxygen molecules diffuse into the cell. However, because the movement of molecules is random, occasionally oxygen molecules move out of the cell (against the concentration gradient).
HapusWhat are the examples of Distillation in chemistry? Explain.
BalasHapusDistillation is the technique of heating a liquid to create vapor which is collected when cooled separate from the original liquid. It's based on the different boiling point or volatility values of the components. The technique may be used to separate components of a mixture or to aid in purification.
BalasHapusThe equipment used for distillation may be called a distillation apparatus or still.
A structure designed to house one or more stills is termed a distillery.
Distillation Example
Pure water can be separated from salt water through distillation. Salt water is boiled to create form steam, but the salt remains in the solution. The steam is collected and allowed to cool back into salt-free water. The salt remains in the original container.
