Explanation:1) Diatomic Gas Consider a gas of noninteracting diatomic molecules. The rotational energy of the molecules can be MODELLED as a rigid quantum rotator with energy levels Erot(l) with degeneracy g(l) given by: Erot(l) = l(l + 1) ~ 2 2I g(l) = 2l + 1 l = 0, 1, 2, ... Where I is the moment of inertia. The Hamiltonian for the system is then: H = P 2 2m + Erot a) Find the canonical partition function of a gas of N non-interacting diatomic molecules. Write this as a product of the partition function for an IDEAL monatomic gas, ZI , and a contribution from the rotational energy, Z = ZIZR. Leave the partition function in the form of a sum. b) This sum can be evaluated at the limits of high and low temperature. For the high temperature limit you can approximate the sum as an INTEGRAL to find the partition function. Use the partition function to find the energy and the specific heat of this gas. This should agree with the equipartition theorem for energy. c) For the low temperature limit, calculate the sum in the partition function for the lowest temperatures where the rotational motion of the molecules MAKES a contribution. This will be where only the lowest rotational levels are significant, for l = 0, 1. Calculate the energy and specific heat of the gas. SOLUTION: a) Z = 1 N! V N Λ3N ( X∞ l=0 (2l + 1)e −βl(l+1)~ 2/2I ) N b) U = 5/2N kT c) Keep only l = 0, 1, 2 in the sum for the partition function. Cv = 3/2N k + 6Nθ2 e 2βθ+3 1 kT2

The MOLAR VOLUME is the volume occupied by one mole of any gas, at room TEMPERATURE and pressure. ... The molar volume is EQUAL to 24 dm 3 (24,000 cm 3).

More the chelation TENDENCY, more is the STABILITY of complex because ENTROPY DECREASE as chelation occurs and stability increases.

0.9gms metal REQUIRES 100ml of 1N HCl⇒ Volume of HCl=100mlNormality of HCl=1N⇒ Weight of HCl= 1000N.Eq.Wt×V [∵ Normality formula] = 10001×1×100 =0.1gmWe KNOW, Equivalent Weight of Metal is the mass of metal required to produce 1GM of H 2 ⟶(1)Also, We know 0.1gm of HCl gives 0.1gm H 2 ⇒ 1gm HCl Gives 1gm H 2 Now, if 0.9gm metal requires 0.1gm HCl⇒1gm HCl will require 0.11×0.9 gm metal∴ Mass of metal which produces 1gm H 2 =9gm∴ From (1) Equivalent Weight of Metal= 9gm

n-rich and electron-deficient atoms. It is best for ammonia and carbon dioxide.Explanation:A Coordinated bond is formed between electron-rich and electron-deficient atoms. The donor atom should have at least one lone pair of electrons and the ACCEPTOR atom should have at least one vacant orbital.In NH₄⁺, the nitrogen in NH₃ is electron-rich and H⁺ ions do not any electron. Thus nitrogen from NH₃ shares a pair of electrons with H⁺ to make a coordinate bond.Each of the covalent bonds that we have looked at so far has involved each of the atoms that are bonding contributing one of the electrons to the shared pair. There is an alternate type of covalent bond in which one of the atoms provided both of the electrons in a shared pair. Carbon MONOXIDE, CO, is a toxic gas that is released as a by-product during the burning of fossil fuels. The bonding between the C atom and the O atom can be THOUGHT of as proceeding in this way.

Groups cannot be DEFINED simply as three or more people TALKING to each other or meeting TOGETHER. Instead, a PRIMARY characteristic of groups is that members of a group are dependent on one another for the group to MAINTAIN its existence and achieve its goals.

Now, among all the ions GIVEN to us, the Al+3 ion is the smallest in size because it has lost 3 electrons so it becomes very small as compared to other ions (the effective nuclear charge increases to a MAXIMUM amount). So, It will have maximum POLARIZING power.

tion:Therefore, to CALCULATE the atomic mass of element X, we need to calculate the mass of 6.022 × 1023 ATOMS of X. HENCE, the atomic mass of element X is 12 u. Carbon has an atomic mass of 12 u; therefore, element X is carbon.

mistry LABORATORY stereotypically uses various forms of laboratory glassware. HOWEVER glassware is not central to chemistry, and a great DEAL of EXPERIMENTAL (as well as applied/industrial) chemistry is done without it.

tion:The Solid State Conference series was founded by Prof. Frumar as a symposium for scientists working in the field of solid state chemistry, chemistry and physics of novel inorganic MATERIALS. New concepts, approaches, fundamental understanding, as well as the application aspects of inorganic materials have been discussed. The conference is a truly international event with a worldwide geographical distribution of the participants.The SSC2020 is planned to be a forum for presentation of new results in the area of solid state chemistry and also for bridging the gap between scientific understanding and technical requirements and application, emphasizing enormous potential of solid state chemistry, materials and technologies, in today’s world.Special attention will be paid to participation of young scientists and early STAGE researchers, who will have an opportunity to meet the leaders in their particular field of research and present their result. A student poster competition is planned, with prize allocated for the 3 best posters, to encourage further scientific development of PHD students.In 2020 the conference will be for the first time organised by FunGlass Centre of the ALEXANDER Dubček UNIVERSITY of Trenčín.
