Show that wavefunction ψ1(x) = (2/L)1/2sin(πx/L) of a particle in a box is an eigenfunction of the operator d2 /dx2 and also calculate the corresponding eigenvalue.
The enthalpy change (ΔH) in a reaction is equal to the heat input under conditions of constant pressure and temperature. It is not equal to the total energy change, as work may be
Ion mobility: Ion mobility is related to molar conductivity by the equations: which allows the mobilities, u+ and u- of the cation and anion to be determined from mol
Explain cesium fluoride Compound (2), cesium fluoride, would be most likely to exist as an ionic species, due to Cs and F come from opposite corners of the periodic table.
Principle underlying the quantitative analysis: In flame photometry, the thermal energy from flame is utilized to convert the analyte within gaseous atoms and then to excite t
What is Standard deviation? Standard deviation tells about the widely spread out of the measured analytical data points. Highly precised measurements are less standard deviation.
Purification of organic compounds Several methods are available for the purification of substances. Though, the selection of method, depends upon the nature of substance (if s
