romotes the CHLORINATION of AROMATIC molecules such as benzene, when chlorine (Cl2) is ADDED. The AlCl3 is REGENERATED, and HCl is a byproduct. The Friedel-Crafts reaction is also promoted byAlCl3. In Friedel-Crafts acylation, the PRODUCT is an aromatic ketone, and the byproduct is HCl

Li3N., So the PRDUCT is LITHIUM NITRIDE.

t that we write ALL the chemical COMPOUNDS within brackets. It's only the complex/co-ordination compounds that we write in brackets.The AIM is to separate the two VALANCIES of the metal atom in a coordination compound namely, the primary and secondary valency."GENERALLY" primary valency is written outside square brackets and secondary valency is written inside square brackets, in circular brackets. Example : [Ag(NH3)2]Cl.Here primary valency = one chloride ionSecondary valency = two ammonia molecules.Hope this helps you.

py of the PERIODIC Table of Elements, find the relative atomic mass of each element in the molecule. Then, multiply the atomic mass of an element by the number of atoms of the element in the molecule. To complete the calculation, ADD up the mass of all of theatoms to GET the molecular weight.ex. Methane (CH9).. 1 carbon atom. and 9 hydrogen atom.

m PLATING is done on taps and BICYCLE handled as it acts as a protection for the inside METAL from rusting. Chromium does not rust. ALSO it's shiny appearance is significant

ium or POTASSIUM salts of long chain fatty acids. When triglycerides in fat/oil REACT with aqueous NaOH or KOH, they are CONVERTED into soap and GLYCEROL. This is called alkaline hydrolysis of esters. Since this reaction leads to the formation of soap, it is called the Saponification .

nitrate = 1g lead nitrate in 100g WATER. ( This is TECHNICALLY incorrect I know, but it is the simplest way of doing this problem) Solution = 10G Pb(NO3)2 in 1.0kg water Molar mass Pb(NO3)2 = 331.2200 g/MOL 10g Pb(NO3)2 = 10/331.22 = 0.030 mol in 1kg solvent solution is 0.03 molal Kf for water = 1.86°C /m.kg van't Hoff factor for Pb(NO3)2, i = 3 molality = 0.03m DELTA T = i*Kf*m delta t = 3*1.86*0.03 delta T = 0.168°C The solution will freeze at - 0.168°C.

2OH ➡️ RCH=NOH + H2O.so, the PRODUCT is an OXIME.

SO4---∆->Fe2O3 + SO2 + SO3.(B) THERMAL DECOMPOSITION reaction is taking place. (Endothermic also)

n't ABSORB They CONDUCT ELECTRICITY because electrons can FREELY move inside ionic bonds

n binding energy, ALSO called ionization potential, is the energy required to REMOVE an electron from an atom, a molecule, or an ion. In GENERAL, the binding energy of a single proton or NEUTRON in a nucleus is approximately a million times greater than the binding energy of a single electron in an atom.

ity of a substance is its maximum AMOUNT that can be DISSOLVED in a specified amount of solvent. It depends upon the NATURE of SOLUTE and solvent as well as temperature and PRESSURE.

this question is phrased makes me very uneasy. The GIVEN information only REFERS to the stoichiometry of the reaction[math]HOAc + EtOH → EtOAc + H_2O[/math]But it says nothing about the concentrations or quantities of the reactants prior to the reaction. (I’m assuming the concentrations of the products were both ZERO to start with.)If we make the unwarranted inference that we the reaction mixture consists entirely of 1 mol of HOAc and 1 mol of EtOH and no inert solvent, then it is possible to calculate a Kc. But I want to be clear that the inference is in no WAY justified by the problem statement.At the end of the reaction, we will have 2/3 mol of EtOAc, 2/3 mol of H2O, 1/3 mol of HOAc, and 1/3 mol of EtOH. They are all contained within the same volume, and since there are EQUAL numbers of constituents on reactant and product sides, we don’t have to bother converting quantity to concentration.[math]K_c = \frac{[EtOAc][H_2O]}{[HOAc][EtOH]} = \frac{\frac{2}{3}^2}{\frac{1}{3}^2} = 4[/math]

ydrides (ALSO KNOWN as saline hydrides or pseudohalides). These compounds form between HYDROGEN and the most active METALS, ESPECIALLY with the alkali and alkaline-earth metals of group one and two elements. In this group, the hydrogen acts as the hydride ion (H− ).

ion with a concentration of HYDROGEN ions higher than 10-7mol/Lis acidic, and a solution with a lower concentration is alkaline (another way to say basic). Using the formula, PH=-log[H+], a pH of 7 is neutral, a pH less than 7 is acidic, and a pH GREATER than 7 is basic.

um aluminum SULFATE, ALSO known as potassium alum or potash alum, has a molecular formula of K2(SO4) ... Ammoniumalum is produced by the evaporation of a WATER solution CONTAINING ammonium sulfate and aluminum sulfate. It can also be obtained by treating a mixture of aluminum sulfate and sulfuric acid with ammonia.hope it helps u plz mark me as BRAINLIST

olution of the electron in a circular ORBIT is not expected to be stable. any particle in a circular orbit would undergo acceleration. during acceleration, charged particles would radiate energy. THUS, the revolving electron would lose energy and finally fall into the nucleus. if this were so, the ATOM should be highly UNSTABLE and hence matter would not exist in the FORM that we know. we know that atoms are quite stable.

cting GROUP or protective group is introduced into a MOLECULE by chemical modification of a functional group to obtain chemo selectivity in a subsequent chemical REACTION.. Then, these PARTS, or groups, must be protected.Deprotection of functional group is to remove the protected functional groupHope this HELPS

wer to why chlorine has an ATOMIC WEIGHT of 35.5 not 35 is because of something CALLED isotopes. Isotopes are atoms with the same number of protons (in the case of chlorine that MEANS 17 protons) but different numbers of neutrons. Chlorine has two common isotopes,Chlorine-35 and Chlorine-37.
