Answer:
This is the tendency for particles in suspension to settle out of fluid in which they are contained and come to rest against a barrier.
Explanation:
In sedimentation, the particles are in a fluid and under the influence of forces , for example, gravitational forces, they settle and then come to rest when faced with a barrier.
The settling process is the process in which the particles fall out of liquid and sedimentation is the end of the process.
Octet rule says that elements with less electrons in their valence shell either tend to lose electron or combine with other element to attain configuration of its nearest noble gas. For example, Na has electronic configuration of 1s2, 2s2, 2p6, 3s1 whereas Cl has electronic configuration of 1s2, 2s2, 2p6, 3s2, 3p5. Chlorine is one of the most electronegative element therefore it will accept one electron from donor and complete its octet. Whereas, Na is one of the electropositive element therefore it will lose its one electron from valence shell to attain stable octet.
<span>The scientific knowledge that
was necessary for Schrodinger’s work is the Bohr’s model. Unlike the Bohr
model, the quantum model does not define the exact path of an electron. The electron
is likely to be in a less dense area of cloud.</span>
Answer: An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts

Answer:
V₂ = 4.0L
Explanation:
Decreasing temperature => Decreasing Volume (Charles Law)
For a given volume, use a temperature ratio that will give a smaller volume.
Volume at lower temp = 4.6L(70K/82K) = 4.0L ... Using (82K/70K) would give a larger volume => contrary to temperature effects on gas volumes when pressure and mass are kept constant.
Pressure effects on Gas Volumes:
Note: The same idea is applied to pressure effects on gas volumes also except that changes in pressure affect gas volumes indirectly. That is, an increase in pressure => decrease in volume, or a decrease in pressure => increase in volume. Boyles Law => V ∝ 1/P.
Given a gas volume of 4.60L at 760mmHg, what is volume at 848mmHg?
Increasing pressure => Decreases Volume (Boyles Law)
For the given volume use a pressure ratio that will give a smaller volume.
Volume at higher pressure = 4.6L(760mm/848mm) =4.1L. Using (848mm/760mm) would give a larger volume => contrary to pressure effects on gas volume when temperature and mass of gas are kept constant.
