@ arathi no , ncert examples and exempler are sufficient for chemistry only tht too for physical chemistry u need to solve p bahadur . so, ncert is only besic and it can reach you upto the cutoff...
An can element X with to the electronic configuration 1S2 2s2 2p6 3s2 would be expected to form the chlorine with formula
the metal will be from II(A) Group i.e can be Be,Mg,Ca Etc. since, M 2+ PO 4 3- By cross multiplication we get this formula.
From MnO4- MnO4- + Fe2+ ----> Fe3+ + Mn2+ n1 * 5 = n2 * 1 (0.1V)*5 = n2 n2 = 0.5V From K2Cr2O7, Cr2O7^2- + Fe2+ --------> Fe3+ + Cr3+ n0 * 4 = n2 * 1 (0.1V)*4 = n2 n2 =0.4V Comparing both moles that...
pressure is directly prop to temp at constant volume. so here v is const and no of moles is constant.so p= a constant * T …........ P/T = a CONST
If the liquid is in an open container and exposed to normal atmospheric pressure, the liquid boils when its saturated vapour pressure becomes equal to 1 atmosphere. that is called as saturated water...
For immiscible mixtures, the relation in pre partial pressures and mole fractioon is: Pa’/Pb’ = na/nb 0.2P/P = na/(114/114) na = 0.2 moles of solute. Mass of the solute = 0.2 * 40 => 8 grams.
In Lithium metaBorate the no. of hydrogens can be donated is superficcil than in compare to Li tetra Borate. Therfore by definition of acid – base lithium tetra borate is considered as acidic flux...
@ thiyagara u can use the arrhenius theory with dillution experimental setup to proov the debye huckel onsagar equation . which states that del (m ) = del not ( m ) – K root over of C where C is the...
The outer most orbital of Cl is 3rd orbital .In this orbital 1electron jump from 3p^5 subshell to vacant 3d .So two unpaired in P and one unpaired in d .hence 3 F atom comes and bond formed with...
Okay let suppose U find out the i that is von’t hoff factor. And also lets for sake we assume after solving we get something i = 5. And also assume the complex be => Co3+ [(Cl)x (NH3)y]z- The...
HEI THERETHE NORMALITY OF FINAL SOLUTION IS DETERMINED BY THE CONCENTRATION OF OH- INFACT ,SO CALCULATING THAT IT COMES OUT TO BE 23 mmol =23m
@ arjun hydrogen bonding is the third catagory of van der walls force , its just the same as that of dipole dipole interaction , just it got a special name , but its extremly stronger than dipole...
enthalpy is the some of internal energy and pressure volume work or it is the heat q at const...
find interplanar distance d using the brags eqn n-\ = 2dsin theta where n=2 wavelength = 1.0 A’ theeta = 60”
Aluminium reacts with steam to form Aluminium oxide and Hydrogen gas is liberated. 2Al+3H 2 O=Al 2 O 3 +3H 2
Oxygen being more electronegative than Cl, oxygen retains its oxidation stat of -2. So, it mans that Chlorine will have an oxidation state of +1 in this compound.
mole fraction = 0.1= > 1/10 = > 1/(1 + 9) Hence moles of solvent that is of H2O is: = > 9. molality = moles of solute/mass of solvent in Kg = > 1*1000/(9*18) = > 6.1 m
Work done isothermally in reversible process is given as: W = – nRT * log(P1/P2) put all the values, W = – 5R*300*log(10/2) = > 20 KJ (approx.) W = F x displacement = > mgd where d = 1 m. W = 20,000...
