Enthalpy change is the change of material energy.
Negative q of reaction enthalpy divided by molar multiplication coefficient
In the enthalpy circle, the formula of enthalpy of formation is the enthalpy change of products minus the enthalpy change of reactants.
Enthalpy of formation is the energy that changes at normal temperature and pressure, and its reactant is simple substance.
It can release heat and absorb heat.
Enthalpy of combustion is exothermic.
The path in the enthalpy circle
Enthalpy of combustion is the enthalpy change of reactants minus the enthalpy change of products.
The reactant of solubility enthalpy is ionic bond.
The reactant of hydration enthalpy is dissolved.
The reactants with intermediate enthalpy are acid and base.
atomization
The reactant of enthalpy is simple substance.
The formula of reaction enthalpy is negative q divided by mole.
The enthalpy of combustion is exothermic in nature.
The reactant of solubility enthalpy is ion.
The reactant of hydration enthalpy is dissolved in water.
The enthalpy of neutralization is the reaction between acid and base.
Enthalpy of atomization changed from normal to gas.
Exothermic and endothermic must be remembered.
Do you know the calculation method between enthalpy changes?
Catalysts are substances that change energy.
Gus's law holds the enthalpy circle in hand to mark the reaction path.
Enthalpy circle formula depends on the enthalpy of formation or combustion.
Lattice energy's reactant is ion.
It's usually gaseous.
All are exothermic.
The formula is to subtract all the numbers
Ionization energy is the absorption of electrons.
It depends on the radius.
It can only be endothermic.
Electron affinity energy
The change of lattice energy depends on the charge.
Also depends on the radius of the atom.
Subtract each number from the enthalpy circle.
The numerical change of ionization energy is always positive.
The affinity energy of the first electron is negative.
In order to attract that electron
The second electron affinity energy
Starting to absorb energy is always positive.
Lattice energy, ionization energy, electron affinity energy.
Are three separate enthalpy changes.
If ionization is negative
So for whom do electrons exist?
The numerical change of lattice energy depends on the charge.
Also depends on the radius of the atom.
Subtract each number from the enthalpy circle.
The numerical change of ionization energy is always positive.
