Explain the problem surrounding the ammonia-making process in terms of chemical equilibrium.
bazaltina [42]

Answer is: at lower temperatures the reaction rate would decrease.

The lower is the temperature, the slower the reaction becomes.

The Haber process is procedure for the production of ammonia, in this process atmospheric nitrogen (N₂) is converted to ammonia (NH₃):

N₂ + 3H₂ ⇄ 2NH₃ ΔrH = -92 kJ/mol.

Because this is exothermic reaction (enthalpy is less than zero), at lower temperatures, the equilibrium is in favor of ammonia, but the reaction doesn't proceed at a detectable rate.

If the temperature changes in a chemical reaction, what has occurred?
bazaltina [42]

Answer:

Energy was transferred

Explanation:

If the temperature changed, energy must have been added or lost, but not created. Energy can't be created or destroyed.

In acidic solution, the sulfate ion can be used to react with a number of metal ions. One such reaction is SO42−(aq) Sn2 (aq)→H2
Sav [38]

Answer:

SO₄²⁻(aq) +Sn²⁺(aq) +4H⁺ → H₂SO₃(aq) + Sn⁴⁺(aq) + H₂O

Explanation:

At first calculate the oxidation state of that element which undergoes oxidation as well as reduction.

for SO₄²⁻ the oxidation state of sulphur is +6 and H₂SO₃ the oxidation state of sulphur is +4

So balance equation is

(Reduction)      SO₄²⁻ + 4H⁺+ 2e⁻ → H₂SO₃ + H₂O.........................................(1)

(oxidation)        Sn²⁺ → Sn⁴⁺ + 2e⁻ .............................................................(2)

Adding equation 1 & 2

we get

SO₄²⁻(aq) +Sn²⁺(aq) +4H⁺ → H₂SO₃(aq) + Sn⁴⁺(aq) + H₂O

An ethylene gas torch requires 3200L of gas at 3.0 atm. What will be the pressure of the gas if the Ethylene is supplied by a 25
drek231 [11]

Answer:

38.4 atm.

Explanation:

  • We can use the general law of ideal gas:<em> PV = nRT.</em>

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 different values of P and V:

<em>(P₁V₁) = (P₂V₂).</em>

P₁ = 3.0 atm, V₁ = 3200 L,

P₂ = ??? atm, ​V₂ = 250.0 L.

∴ P₂ = (P₁V₁)/(V₂) = (3.0 atm)(3200 L)/(250.0 L) = 38.4 atm.
