S stands for Sulphar.H stands for Hydrogen.
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'.
H2(g) + S(s) H2S + 20.6 kJ
The oxidation number of sulphur in H2S is 2.
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.
CdS(s)+H2SO4(aq)--> Cd2SO4(aq)+H2S(g) one of the byproducts of this reaction will be gas Hydrogen Sulfide, H2S

H2(g) + S(s) H2S + 20.6 kJ
The oxidation number of sulphur in H2S is 2.
The elements in hydrogen sulfide (H2S) are hydrogen (H) and sulfur (S).
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.
H stands for hydrogen and S stands for sulfur combine them together it makes H2S
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).
CdS(s)+H2SO4(aq)--> Cd2SO4(aq)+H2S(g) one of the byproducts of this reaction will be gas Hydrogen Sulfide, H2S
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.
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)
sure (S)
Hydrogen gas (H2) plus sulfur (S) produce hydrogen sulfide (H2S).H2 + S ---> H2S
