What is Pauli’s exclusion principle? Pauli’s exclusion principle – “No two electrons in an atom can have the four quantum numbers identical.”

What is solvent extraction? The separation of an organic compound from a mixture by dissolving it in a suitable solvent is known as solvent extraction.

Why does the solubility product increase with increasing temperature? The solubility product (Ksp) is a measure of the solubility of a compound in a solution. It is the product of the concentrations of the ions in solution at equilibrium. The higher the Ksp, the more soluble the compound is. The solubility of a compound is … Read more

Why is 2d orbital not possible? A 2d orbital is not possible because the angular momentum quantum number (l) can only have values from 0 to n-1, where n is the principal quantum number. In the case of a 2d orbital, n = 2, so l can only have values of 0 and 1. A … Read more

What is law of mass action? The law of mass action is a principle in chemistry that states that the rate of a chemical reaction is directly proportional to the product of the concentrations of the reactants. The law of mass action can be used to explain and predict the behavior of solutions in dynamic … Read more

What is a quantum number? A quantum number is a number that describes the state of a quantum system. In the context of atoms, quantum numbers are used to describe the energy, angular momentum, and spin of electrons. There are four quantum numbers that are used to describe electrons: Principal quantum number (n): This quantum … Read more

What is heat of solution? The heat of solution, or enthalpy of solution, is the amount of heat released or absorbed when a substance dissolves in a solvent. It is measured in kilojoules per mole (kJ/mol). The heat of solution can be either positive or negative. A positive heat of solution means that heat is … Read more

Activation energy will influence the rate of reaction-Explain it. The difference between the average energy (EA) of the reactant molecules in the initial stage and the average energy (Ex) of the molecules in the intermediate complex stage is called activation energy. The increase or decrease of activation energy is related to the increase or decrease … Read more
