An endothermic reaction is the one that absorbs heat and reveals that heat is consumed in the reaction from the surroundings, hence q>0 (positive). If q is positive, then ΔH is also positive, at constant pressure and temperature for the above equation. in 85/2020 tcu

"WebThe lab had concluded that the molar enthalpy of combustion of magnesium metal was -478kj/mol. Using Hess’s Law the enthalpies for each reaction were calculated and then added. The enthalpy for reaction one was -261kj/mol, and the enthalpy for reaction two was 69/mol. The third reactions enthalpy had been given, which was -286kj/mol. " - Enthalpy crash course

WebEnthalpy (H) is defined as the sum of the total internal energy stored in the reactants or products. However, one cannot determine absolute enthalpy due to numerous un-controlled variables involved, but the change in enthalpy can be calculated. Change in enthalpy of combustion or ΔH is equal to the amount of heat lost or gained by the system. WebPV=k (at a constant temperature) pressure x volume = constant. Boyle's Law. PV=k. Charle's Law. volume divided by temperature equals a constant as long as the pressure remains the same. Avogadro's Law. volume divided by the number of moles in the container at a constant pressure and temperature gave yet another constant. The Ideal Gas Law.
