What is the correct compound name for h2s?
No such compound as 'h2s'. If you mean ' H2S'. then it is hydrogen sulphide. NB . When writing elemental symbols in a formula, single letter symbols are ALWAYS a CAPITAL letter. Hence Hydrogen is 'H' ; not 'h' Similrly Sulphur is 'S' . not 's'.
Which reaction shows that the enthalpy of formation of H2S is Hf -20.6 kJ mol?
H2(g) + S(s) H2S + 20.6 kJ
What is the oxidation number of sulphur in the equation of combustion of H2S?
The oxidation number of sulphur in H2S is 2.
Which reaction shows that the enthalpy of formation of H2S is Hf -20.6 kJmol?
The reaction that shows the enthalpy of formation of H2S as -20.6 kJ/mol is: 2H2(g) + S(s) → 2H2S(g) with ΔH = -20.6 kJ/mol. This means that forming 1 mole of H2S from its elements H2 and S releases 20.6 kJ of energy.

What is the oxidation number of sulphur in the equation of combustion of H2S?
The oxidation number of sulphur in H2S is 2.
What are the elements in H2S?
The elements in hydrogen sulfide (H2S) are hydrogen (H) and sulfur (S).
Which reaction shows that the enthalpy of formation of H2S is Hf -20.6 kJmol?
The reaction that shows the enthalpy of formation of H2S as -20.6 kJ/mol is: 2H2(g) + S(s) → 2H2S(g) with ΔH = -20.6 kJ/mol. This means that forming 1 mole of H2S from its elements H2 and S releases 20.6 kJ of energy.
What is the compound chemical formula for h2s?
H stands for hydrogen and S stands for sulfur combine them together it makes H2S
What is H2S on the periodic table?
You will not find H2S on the periodic table. The periodic table contains only elements, and H2S is a compound, made of two elements, hydrogen (H) and sulfur (S).

Is H2S O2 equal to S H2O?
No, H2S and O2 are not equal to S and H2O. H2S is hydrogen sulfide, O2 is oxygen gas, S is sulfur, and H2O is water. The equation for the reaction between H2S and O2 to form S and H2O is 2H2S + 3O2 → 2S + 2H2O.
How many grams of sulfur can be prepared from 1.40 kg of H2S?
1.40 kg is equal to 1.40 / 0.03418= 40.96 mole H2S, thus 40.96 mole of S (sulfur) which is 40.96 * 0.03207= 1.31 mole S(0.03418 and 0.03207 are molar masses of H2S and S respectively in kg/mol)
In the h2s molecule which atom is more electonegative?
sure (S)
What compound is made by hydrogen and sulphur?
Hydrogen gas (H2) plus sulfur (S) produce hydrogen sulfide (H2S).H2 + S ---> H2S
