Different Changes in Enthalpy symbols -ΔH

[Joshua Hughes 1L]

Can someone go over with me the different meanings of the different symbols, please. I think I know the one with the degree symbol in the corner and the enthalpy of formation ΔHf and ΔHfus and the like but there a few others I was kind of unfamiliar with:
ΔHc
ΔHL
ΔHb

[SPandya1F]

ΔHc is the enthalpy of combustion.
ΔHL is the lattice enthalpy (ions).
ΔHb is bond enthalpy.

[Anna Li 2E]

ΔHc=enthalpy of combustion. This is when one mol of a compound is burned completely in oxygen.
ΔHL=lattice enthalpy of formation. An example of this would be how the gaseous form of Na+ and Cl- come together to create NaCl solid.
ΔHb=bond enthalpy which is the energy released when bonds are made.

[Warda Sahib 2J]

ΔHc-enthalpy of combustion; ΔHL-lattice enthalpy; ΔHb is bond enthalpy.
