Stoichiometry Heat of transition is the heat evolved or absorbed, when a substance is converted from One allotropic form to another allotropic form Solid to liquid Vapor to liquid Vapor to solid One allotropic form to another allotropic form Solid to liquid Vapor to liquid Vapor to solid ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry No cooling occurs, when an ideal gas undergoes unrestrained expansion, because the molecules Are above the inversion temperature Exert no attractive force on each other Do work equal to loss in kinetic energy Collide without loss of energy Are above the inversion temperature Exert no attractive force on each other Do work equal to loss in kinetic energy Collide without loss of energy ANSWER DOWNLOAD EXAMIANS APP
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 Only OH⁻ and H⁺ ions react in every case The strong base and strong acid reacts in aqueous solution The salt formed does not hydrolyse The strong base and strong acid reacts completely Only OH⁻ and H⁺ ions react in every case The strong base and strong acid reacts in aqueous solution The salt formed does not hydrolyse ANSWER DOWNLOAD EXAMIANS APP
