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.
0.45 g of anhydrous oxalic acid is reacted with 50 ml of KMNO4 . Then normality of KMnO4 is??
Question: Does the number of steps in a reaction process affect the enthalpy change of the overall reaction? Hypothesis: To compare experimental data to functionality of He
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
The quantity of heat liberated of absorbed when one mole of compound is formed in its standard state from its elements in their standard state is known as standard heat of formatio
Quantum numbers of an atom can be defined on the basis of: (1) Hund's rule (2) Aufbau's principle (3) Pauli's exclusion principle (4) Heisenberg's uncertainty principl
