Demonstrate Pauli principle for the wavefunction describing bond between two hybrid orbitals in Q2 (you need to show using spin wavefunction that interchange of the labels changes the sign of wavefunction) .

The molar mass of a substance is defined as the mass of 1 mol of that substance, expressed in grams per mole, and is equal to the mass of 6.022 × 10 23 atoms, molecules, or formula units of that substance.

The answer is false because: gravitational force is independent of medium and depends only on the masses of the two objects and the distance between them

In reversible reaction chemistry equilibrium is attained when the forward and reverse reactions are taking place at the same rate, thus, the concentrations of reactants and products remain the same. a reversible reaction is a chemical reaction where the reactants form products that, in turn, react together to give the reactants back. in irreversible reactions on the other hand, the reactants react to form the products, which cannot revert back into reactants.
