The Calorific Value for Hydrogen is 141,790 kj/kg, taken from Engineering Toolbox.
scale pH <--- HUH? hehe
Hydrogen gas is not edible or safe for human consumption. Inhaling hydrogen can be harmful and it does not provide any nutritional value to the body. It is important to only consume substances that are safe and intended for human consumption.
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.
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
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.
The expectation value of kinetic energy for a hydrogen atom is -13.6 eV.

hydrogen calorific value is 150000 kJ/kg
No, sulfur is more electronegative than hydrogen. Hydrogen has an electronegativity value of 2.20 on the Pauling scale, while sulfur has a value of 2.58. This means sulfur has a greater tendency to attract electrons in a chemical bond compared to hydrogen.
Hydrogen has the highest calorific value, which should make it good fuel
scale pH <--- HUH? hehe
The pH scale indicates the concentration of hydrogen ions in a solution. A lower pH value indicates a higher concentration of hydrogen ions, while a higher pH value indicates a lower concentration of hydrogen ions.
Coal
If you think to electrical charge the hydrogen ion (H+) is a cation. In water other species as (H3O)+ can exist.
Water has a pH value of 7, meaning it is neutral. The hydrogen ions (H+) and hydroxide ions (OH-) are balanced in water, resulting in a neutral solution.
The atomic weight (not mass) of hydrogen is: [1,00784; 1,00811]; the conventional value is 1,008. The atomic weight (not mass) of oxygen is: [15,99903; 15,99977]; the conventional value is 15,999.
