From the reaction;
2SO2(g) + O2(g) = 2SO3(g) + 394 kJ
In the reaction a mixture of plantinum and vanadium (V) oxide may be used as a catalyst for the reaction. The sulfur trioxide produced is then used to make sulfuric acid.
The energy that is required to release 1 mole of sulfur trioxide is +394 joules
For one mole of sulfur trioxide;
the energy that will be released will be 394/2 = 197 kJ
Thus; the amount of energy released is +197 kJ
Answer:
Basee is the answer hope its write xd
6 molls
As a result, if two moles of dinitrogen gas are specified, six moles of dihydrogen gas are needed.
Answer:
7.63 L is the produced volume of ammonia.
Explanation:
The balanced reaction of decomposition is this:
(NH₄)₂CO₃ (s) → 2NH₃ (g) + CO₂ (g) + H₂O (g)
We convert the mass of carbonate to moles → 15 g . 1mol / 96g = 0.156 mol
Ratio is 1:2, so the 0.156 moles will produce the double of moles of ammonia. → 0.156 . 2 = 0.312 moles
We use now, the Ideal Gases Law to determine the volume
Pressure . Volume = moles . R . T
T → 25.5°C + 273 = 298.5K
1 atm . V = 0.312 mol . 0.082 L.atm/mol.K . 298.5K
V = (0.312 mol . 0.082 L.atm/mol.K . 298.5K) / 1 atm → 7.63 L
