The symbol for atomic hydrogen is H. But hydrogen as a gas molecule consists of two hydrogen atoms, so the formula for molecular hydrogen is H2.
Hydrogen is a diatomic element, so the formula would be H2.The chemical symbol is H, but hydrogen usually appears as H2.
H is the atomic symbol for hydrogen. H2 is the chemical formula for the hydrogen molecule, which is the most common and stable form of hydrogen gas.
"H" is the chemical symbol for Hydrogen. "H2" is the symbol for a molecule that contains two atoms of hydrogen. Under normal conditions in the Earth's atmosphere, hydrogen gas is usually found in the form of molecules consisting of two atoms.
A chemical equation, like all equations, contains an equals sign ( = ). It shows a chemical reaction, where something turns into something else. You probably mean the chemical symbol that would represent hydrogen. The symbol for an atom of hydrogen is H. In hydrogen gas the atoms usually pair up into hydrogen molecules for which the symbol is H2. If the gas is very hot the molecules dis-associate, so then the symbol will be just H, or sometimes (H) to make it clear that monatomic hydrogen is referred to. If you want an equation : H2 + heat = 2 (H)
Hydrogen is a gas. H2 is the description of its molecular structure (2 hydrogen atoms bound together).

I don't know what "hot water gas" means exactly, but water gas is a mixture of CO and H2.
Hydrogen gas is H2
H2S is the formula of Hydrogen sulfide.
