The enthalpy of combustion is the enthalpy change
when one mole of the pure compound is formed from its elements under standard conditions
when 1 mole of pure substance is completely burned in excess oxygen, under the given temperature and pressure of the reaction
when 1 mole of H+ (aq) ions from acid reacts with 1 mole of OH- (aq) ions from an alkali to form 1 mole of water under the stated condition of the experiment
the magnitude of the enthalpy change of a chemical reaction depends only on the difference in the enthalpy content of the products and the reactants, and does not on how the reaction is completed

What is the name of this enthapyl change
Enthalpy change of formation
Enthalpy change of combustion
Enthalpy change of reaction
Enthalpy change of atomisation
MgCl2(s) ---> Mg2+(g) + 2Cl-(g)
This equation represents
Enthalpy of hydration
Enthalpy of solution
Lattice enthalpy of dissociation
Lattice enthalpy of formation
Which of the following equations represents the enthalpy change of combustion?
2C4H10(g) +13O2(g) → 8CO2 (g) + 10H20(g)
C4H10(g) +13/2O2(g) → 4CO2 (g) + 5H20(g)
C4H10 + 9/2O2 = 4CO (s)+ 5H2O
C4H10 + 5/2O2 = 4C(s) + 5H2O(g)
