How many moles of hydrogen sulfide are contained in a 64.6-g sample of this gas?
H2S 63.1 g H2S * 1 mol H2S / 34.076 g H2S = 1.85 mol H2S
Mass And No Of Molecules In 18000 cm3 Of H2S gas at S.T.P?
No of molecules in 18000 cm3 of H2S
How many moles of oxygen are needed to react completely with 2.3 moles of H2S 2H2S plus 3O2 2SO2 plus 2H2O?
H2S (g) + 2 O2 (g) --> H2SO4 (l) 1 mole + 2 mole --> 1 mole You will need 2 moles of O2
How many moles of oxygen are needed to react completely with 2.3 moles of H2S?
Balanced equation: 2H2S + 302 = 2SO2 + 2H20
What is the oxidation number of sulphur in the equation of combustion of H2S?
The oxidation number of sulphur in H2S is 2.
How many moles of hydrogen sulfide are contained in a 64.6-g sample of this gas?
H2S 63.1 g H2S * 1 mol H2S / 34.076 g H2S = 1.85 mol H2S
How many grams of iron II sulfide have to react with hydrochloric acid to generate 12 g of hydrogen sulfide?
FeS+2HCl-->FeCl2+H2S Moles of H2S produced equal to moles of FeS used. Moles of H2S=12\34=0.353mol Grams of Fes=0.353*88=31.05g
Mass And No Of Molecules In 18000 cm3 Of H2S gas at S.T.P?
No of molecules in 18000 cm3 of H2S
How may moles of hydrogen are in H2S?
There are no moles.There are 2 atoms in one molecule.
How many moles of oxygen are needed to react completely with 2.3 moles of H2S 2H2S plus 3O2 2SO2 plus 2H2O?
H2S (g) + 2 O2 (g) --> H2SO4 (l) 1 mole + 2 mole --> 1 mole You will need 2 moles of O2
How many moles of oxygen are needed to react completely with 2.3 moles of H2S?

What is the oxidation number of sulphur in the equation of combustion of H2S?
The oxidation number of sulphur in H2S is 2.
What is H2S?
H2S stands for Hydrogen Sulphide.It is a gas.
How many grams of oxygen are needed to react with 2.5 grams of dihydrogen sulfide?
The molar ratio of oxygen to dihydrogen sulfide in the reaction is 3:1. First, find the number of moles of dihydrogen sulfide by dividing its mass by its molar mass. Then, use the mole ratio to calculate the moles of oxygen needed. Finally, convert the moles of oxygen to grams.
Determine the Theoritical yield of H2S in moles if 4.0 mol Al2S3 and 4.0 mol H2O are reacted?
The balanced chemical equation for the reaction between Al2S3 and H2O to produce H2S is: Al2S3 + 6 H2O -> 2 Al(OH)3 + 3 H2S From the balanced equation, 1 mol of Al2S3 produces 3 mol of H2S. Therefore, if 4.0 mol of Al2S3 is reacted, the theoretical yield of H2S would be 3 * 4.0 mol = 12.0 mol.
How many molecules are there in 17.04g of hydrogen sulfide?
One mole of hydrogen sulfide (H2S) has 34 g (2+32) and 6.022 x 10^23 molecules (Avogadro Constant). Therefore 17.04g is equal to 0.5012 moles (17.04/34), which is equivalent to 3.0182 x 10^23 molecules (0.5012 x 6.022 x 10^23).
How many moles of H will react with 1.72 moles of S?
Hydrogen reacts with sulfur in the proportions dictated by this equation:H2 + S --> H2S. The reactants are in a 1:1 proportion with each other, so 1.72 moles of hydrogen will react with 1.72 moles of sulfur.
