homologous series is a sequence of compounds with the same functional group and similar chemical properties in which the members of the series can be branched or unbranched, or DIFFER by -CH2.

Four characteristics of a homologous series are: (i) The general formula of all compounds in the series is the same. (ii) They have the same functional group. (iii) Their physical properties such as melting POINT, boiling point, DENSITY, generally show a gradual CHANGE with increase of molecular formula in the series.

Answer:

carbon compounds have low melting and BOILING POINT because these compounds are bonded with COVALENT bomd and also forces of attraction between these molecules are not very strong. This is because carbons form covalent bond and are easy to BREAK therefore have low melting and boiling points.

The degeneracy of d-orbitals in an atom depends on the environment in which the atom is present. In a free atom all the five d-orbitals in a subshell are degenerate. In a magnetic field, however, degeneracy is lost.

If the atom is part of a molecule, as,say , the central atom in a transition metal complex, the degeneracy of d-orbitals depends on the geometrical arrangement of ligands around the central atom. In the common cases of tetrahedral and octahedral complexes , the five d-orbitals are split into two sets t2 and e in the former and t2g and EG in the latter. The orbitals in the t2 or t2g sets are triply degenerate while those in the e or eg are doubly degenerate. Remember that a slight distortion in the ideal geometry CHANGES the SPLITTING pattern somewhat. A tetragonal distortion of a regular octahedral complex removes the degeneracy of the dz^2 and dx^2-y^2 orbitals as also of dxy and dxz, dyz. Degeneracy of d-orbitals is also subject to the Jahn Teller effect in NONLINEAR complexes.

For the splitting of d-orbitals in other geometries please look into a good Inorganic Chemistry textbook, e.g., Coordination Chemistry by D Bannerjea or Inorganic Chemistry by Huheey.

Answer:

Electron affinity increases upward across PERIODS of a periodic table for the groups and from left to right, because the electrons ADDED to the energy levels GET closer to the NUCLEUS, making the nucleus and its electrons more attractive.

Explanation:

a)the third period contains eight elements : sodium, magenisum , aluminium, silicon, phosphorus, sulfur, chlorine, and argon.

b) the second period contains the element lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon. In a quantum mechanical descripition of atomic structure , this period corresponds to the filling of the seonds ( n=2) shell, more specially its 2s and 2p subshells.

Answer:

Key point:

Energy flows through an ecosystem and is dissipated as HEAT, but chemical ELEMENTS are recycled.

The ways in which an element—or compound such as water—moves between its various living and nonliving forms and locations in the biosphere is called a biogeochemical cycle.

Biogeochemical cycles important to living organisms include the water, carbon, nitrogen, phosphorus, and sulfur cycles.

Introduction:

What is your body made of? Not to put too fine a point on it: atoms. Lots and lots of them. About 7,000,000,000,000,000,000,000,000,000 to be precise.^1

start superscript, 1, END superscript Where did all of those atoms come from?

If we really walk it backwards, most of the elements that make up our bodies—and those of every other living thing!—were born in dying stars billions of years ago. That's pretty cool, but it doesn't capture the whole picture. What have the atoms of your body been doing more recently, during their time on Earth?

Energy flows, but matter is recycled.

Energy flows directionally through Earth’s ecosystems, typically entering in the form of sunlight and EXITING in the form of heat. However, the chemical components that make up living organisms are different: they get recycled.

What does that mean? For one thing, the atoms in your body are not brand new. Instead, they've been cycling through the biosphere for a long, long time, and they've been part of many organisms and nonliving compounds along the way. You may or may not believe in REINCARNATION as a spiritual concept, but there's no question that atoms in your body have been part of a huge number of living and nonliving things over the course of time

ANSWER: The ABUNDANCE in % for other two ISOTOPES of the oxygen is 99.762% and 0.201%

Explanation :

The average atomic mass of an ELEMENT is the total of isotopic mass times the percent abundance for all the isotopes.

Oxygen has 3 isotope, 160, '70 and 180.

The average atomic mass of oxygen can be calculated as follows.

Average Atomic Mass = (Isotopic mass of 160 x % abundance of 160) + (isotopic mass of "0 x % abundance of "O) + (Isotopic mass of 180 x % abundance of 180)

17 The mass of "O = 16.999 amu and its % abundance is 0.037% which is 0.00037

The mass of 160 = 15.995 amu. Let us assume its % abundance as a

The mass of 180 = 17.999 amu

The total % abundance for all the isotopes is 100% or 1.

Therefore % abundance for 180 would be 1- (a + 0.00037) = 0.99963 a =

Let us plug in the above values in the average atomic mass formula.

Average atomic mass = ( 15.995)(a) + = (16.999)(0.00037) + (17.999)(0.99963 - a)

The average atomic mass of element O is 15.9994

Therefore we have,

15.9994 = 15.995a + 0.0062896 + 17.99234 - 17.999a

15.9994 = -2.004a + 17.99863

-1.99923 = -2.004a

a = 0.99762

a = 99.762%

The percent abundance of 16 O is

99.762%

The percent abundance of 180 is 0.99963 - 0.99762 = 0.00201 or 0.201%
