HF is a very corrosive gas at room temperature. It can even etch glass!
it is at liquid state in room temprature
Na2S
Its melting point is -83.6 °C and boiling point is 19.5 °C. This implies that hydrogen fluoride would be in the gaseous state at room temperature. Its chemical formula is HF.
The Hreaction is the difference between Hf, products and Hf, reactants
No, it is not ionic. HF is covalent.
Hreaction = Hf, products - Hf, reactants
HF
It is a halogen, its most common oxidation state is -1, it is a gas at room temperature (F2), It forms a weak acid (hydrofluoric acid, HF), and it has seven valence electrons.
Na2S
boron
Its melting point is -83.6 °C and boiling point is 19.5 °C. This implies that hydrogen fluoride would be in the gaseous state at room temperature. Its chemical formula is HF.

HF is hydrogen fluoride.
Hreaction = Hf, products - Hf, reactants
Hf is the element hafnium. A dense gray metal. HF is the compound hydrogen fluoride, a toxic, acidic gas.
Hreaction = Hf products - Hf reactants
hf is the energy of photons incident on the surface
