How many moles of each element are in one mole of (nh4)2s? 1 mole of nitrogen, 8 moles of hydrogen, 1 mole of sulfur 1 mole of nitrogen, 6 moles of hydrogen, 1 mole of sulfur 2 moles of nitrogen, 6 moles of hydrogen, 1 mole of sulfur 2 moles of nitrogen, 8 moles of hydrogen, 1 mole of sulfur

2 moles of nitrogen, 8 moles of hydrogen, 1 mole of sulfur.

Explanation:

The ammonium sulfide (NH₄)₂S salt contains:Sulfide anion carries charge of (-2) S⁻².Ammonium group cation carries charge of (-2) NH₄⁺.From the stichiometry of the compound ammonium sulfide (NH₄)₂S: each sulfide anion (S⁻²) combines with 2 ammonium groups (NH₄⁺).If 1.0  mole of (NH₄)₂S dissociated to its atoms, it will give 2.0 moles of nitrogen, 8.0 moles of hydrogen, and 1.0 mole of sulfur.

(NH₄)₂S → 2N + 8H + S

So, 1.0 mole of (NH₄)₂S contains 2.0 moles of nitrogen, 8.0 moles of hydrogen, and 1.0 mole of sulfur.

2.5 L.

Explanation:

We can use the general law of ideal gas: PV = nRT.

where, P is the pressure of the gas in atm.

V is the volume of the gas in L.

n is the no. of moles of the gas in mol.

R is the general gas constant,

T is the temperature of the gas in K.

If n and T are constant, and have two different values of V and P:

P₁V₁ = P₂V₂

P₁ = 5.0 atm, V₁ = 3.5 L.

P₂ = 7.0 atm, V₂ = ??? L.

∴ V₂ = P₁V₁/P₂ = (5.0 atm)(3.5 L)/(7.0 atm) = 2.5 L.
