The Calorific Value for Hydrogen is 141,790 kj/kg, taken from Engineering Toolbox.
calorific value of hydrogen is 150 kilojoule per mole
218 mJ per Mol

Hydrogen chloride is an acid and its acidity depends on the concentration of the solution. For example, a 0.1M solution of HCl has a pH value of 2.0
The conjugate acid is Hydrogen (H2), the pKa of which is 35.
scale pH <--- HUH? hehe
According to the definition, to form a hydrogen bond, a bond with hydrogen and another element should have a higher value for electronegativity such as H-N, H-O and H-F. H-Cl does not meet with sufficient polarity to form a hydrogen bond.
This is because in ammonia there is a nitrogen atom (with a high electronegativity value) that has a lone pair of electronsavailable to form a hydrogen bond with the hydrogen atoms in water. On the other hand although the Phosphorous atom has a lone pair of electrons, it doesn't have a high enough electronegativity value to form a strong hydrogen bond.
It depends on the temperature and pressure of hydrogen or to have the hydrogen density value.

Hydrogen
hydrogen calorific value is 150000 kJ/kg
Hydrogen has the highest calorific value, which should make it good fuel

An admitted value now is 10 ppm.

If you think to electrical charge the hydrogen ion (H+) is a cation. In water other species as (H3O)+ can exist.
Since hydrocarbons do not dissolve in water, they have no pH. That is to say, they do not influence the concentration of either hydrogen or hydroxide ions. They do contain hydrogen, but the hydrogen in a hydrocarbon does not ionize.
The pH value of a particular solution is equivalent to -log[hydrogen ion concentration].
