Stoichiometry Heat of neutralisation of a strong acid and strong base is always a constant value, i.e., 57 KJ/Kg mole. This is because The strong base and strong acid reacts completely The strong base and strong acid reacts in aqueous solution Only OH⁻ and H⁺ ions react in every case The salt formed does not hydrolyse The strong base and strong acid reacts completely The strong base and strong acid reacts in aqueous solution Only OH⁻ and H⁺ ions react in every case The salt formed does not hydrolyse ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry No cooling occurs, when an ideal gas undergoes unrestrained expansion, because the molecules Exert no attractive force on each other Are above the inversion temperature Do work equal to loss in kinetic energy Collide without loss of energy Exert no attractive force on each other Are above the inversion temperature Do work equal to loss in kinetic energy Collide without loss of energy ANSWER DOWNLOAD EXAMIANS APP
