The first ionization potentials for Na, K, and Rb are 5.138, 4.341, and 4.166 eV, respectively. Assume that the energy level of the outer electron can be represented by a hydrogenl
Block diagram of atomic fluorescence spectrometry: The instrumentation for AFS consists of atom reservoir that might be a flame or a furnace etc., a basic source emitting the
The determination of k is not a strait forward exercise. Model it from first principles using Bernoulli's equation would produce a square root relationship and would probably have
An aqueous solution has a hydroxyl concentration of 1.75 x 10^-7mol/L. Find the concentration of hydrogen ions in this solution.
The magnetic quantum number for an electron when the value of principal quantum number is 2 can have: (1)3 values (2) values (3)9 values (4)6 values Ans: 3 values
Geometrical or cis-trans isomerism The compounds that have similar molecular formula but differ in the relative spatial arrangement of atoms or groups in space are termed a
The bond energy of an O- H bond is 109 kcal mol 1. When a mole of water is formed from H and O atoms, then 218 kcal is released. Two O-H bonds are there is H2O so 2*109 kcal an
Step growth or condensation polymerisation In this form of polymerisation monomers usually consist of two functional sets, that is difunctional monomers. In that method no init
