might be due to common ion effect
According to Fajan, if two oppositely charged ions are brought together, the nature of the bond formed between them depends upon the effect of one ion on the other. Whenever two oppositely charged...
Here the answer will be [Fe(CO)5] here the presence of lone pair is 4 which is greater than the other three .Here we will be having four lone pair of back bonding in the presence of CO
melting point depends on the metallic bonding.The stronger the metallic bonding the higher the melting point.The metallic bonding depends on the number of unpaired electron.The more the unpaired...
But the answer is three
Hello Student Ionization potential depends on the size of atom. Smaller the atomic size, higher would be the ionization potential. We know that atomic size of elements decreases along the period and...
Hello Student Melting point highly depends on the number of unpaired electrons. Higher the number of unpaired electrons higher would be the melting point. Melting point increases down the group as we...
Hi Pallavi, 1 dm 3 = 1L so, 2.8 dm3 of oxygen = 2.8 L of oxygen. Now we know tthat at STP, 1 mole of any gas = 22.4 L or 22.4 L = 1 mole so, 2.8 L = (1/22.4) x 2.8 = 0.125 mole

Soxhlet extraction is carried out when the desired compound has a limited solubility in a solvent,and the impurity is insoluble in that solvent. If the desired compound has a significant solubilityin...
Alkali metals constitute the 1 group in periodic table.Thermal Stability is the decomposition of a compound on heating.The higher the temperature required to decompose something, the more thermally...
It is because of the spin. The electrons while spinning creates a magnetic field which can be cancelled by an oppositely spinning electrons. In paramagnetic substances , there are unpaired electrons...
Acomplex ion can be defined ion which consists of a central metal cation to which several anions or molecules are bonded.Now this complex ion may be positively or negatively charged.The metal cation...
it will be the molecular mass of k2cr2o7 devided by 2
because it contains glycerine which is remov
When the ratio of number of cation to anion becomes different from that indicated by the ideal chemical formula, then the defects which arises are called as non – stoichiometric defects.These...
Ligand can be defined as anionormolecule that can binds to a centralmetalatom to form acoordination complex.The bonding between metal and ligand generally involves donation of one or more of the...
Titration with kMnO 4 solution is done in acidic media. . the titration gives unsatisfactory results when carried out in the presence of hcl, because kMnO 4 solution can oxidise hcl to chlorine gas...
ligands are lewis bases and F - is a better base.
i think J D Lee
Beryllium is the first member of alkaline earth metals series which constitute the group II of the periodic table.But Al is the member of boron family of group 13 in periodic table.Beryllium being the...
here 6 is n- factor of k2cr207 (moles of electrons needed to reduce 1 mol. of k2cr2o7)
It is found that ionic mobility of Ca 2+ ,Sr 2+ and Mg 2+ ions in free solution follow the order which is – Sr 2+ > Ca 2+ > Mg 2+ The above order is same for the ionic mobility of the...
