Combined Graduated Level Examination (SSC CGL or CGLE) is an examination conducted by the Staff Selection Commission to recruit Group B and C officers to various posts in ministries, departments and organizations of the Government of India. The Staff Selection Commission was established in 1975.
An electron's being solvated in a solution means it is bound by the solution. [2] The notation for a solvated electron in formulas of chemical reactions is "e − ". Often, discussions of solvated electrons focus on their solutions in ammonia, which are stable for days, but solvated electrons also occur in water and many other solvents – in ...
The commission is headed by a Chairman [5] and two members after him. Besides, there are one Secretary, one Director, one Deputy Secretary, two Joint Directors, nine Under Secretaries, four Deputy Directors, one Finance & Budget Officer, one Assistant Director (OL), 24 Section Officers and more than 183 supporting officers/staff are at the Headquarters for discharging the duties and ...
There are three common types of chemical reaction where normality is used as a measure of reactive species in solution: In acid-base chemistry, normality is used to express the concentration of hydronium ions (H 3 O +) or hydroxide ions (OH −) in a solution. Here, 1 / f eq is an integer value. Each solute can produce one or more ...
The assumption that solution properties are independent of nature of solute particles is exact only for ideal solutions, which are solutions that exhibit thermodynamic properties analogous to those of an ideal gas, and is approximate for dilute real solutions. In other words, colligative properties are a set of solution properties that can be ...
The enthalpy of solution is the solution enthalpy minus the enthalpy of the separate systems, whereas the entropy of solution is the corresponding difference in entropy. The solvation energy (change in Gibbs free energy) is the change in enthalpy minus the product of temperature (in Kelvin) times the change in entropy. Gases have a negative ...
The propensity for any two substances to form a solid solution is a complicated matter involving the chemical, crystallographic, and quantum properties of the substances in question. Substitutional solid solutions, in accordance with the Hume-Rothery rules, may form if the solute and solvent have: Similar atomic radii (15% or less difference)
The Odisha Public Service Commission (OPSC) is a government agency of the state of Odisha, India, responsible for the recruitment of candidates for various state government jobs through competitive examinations.
