Answer:
322 mmHg
Explanation:
Step 1: Given data
- Total pressure of the gaseous mixture (P): 756 mmHg
- Partial pressure of helium (pHe): 229 mmHg
- Partial pressure of nitrogen (pN₂): 205 mmHg
Step 2: Calculate the partial pressure of oxygen (pO₂)
The total pressure of the gaseous mixture is equal to the sum of the partial pressures of the individual gases.
P = pHe + pN₂ + pO₂
pO₂ = P - pHe - pN₂
pO₂ = 756 mmHg - 229 mmHg - 205 mmHg
pO₂ = 322 mmHg
ΔG = -nEF
ΔG = Gibbs free energy change
n = moles of electrones participated in
E = Electrode potential
F = Faraday constant
By substituting,
ΔG = -(3 mol) x 96485 A S/ mol x (-0.46) V
= + 133149.3 J
= + 133 kJ
Hence the answer is "b".
Since ΔG is a positive value, the reaction is non spontaneous reaction.
This is known as a molecule.
Answer:
yes, the trash did disappear when she burned it however it releases smoke into the air (and harmful chemicals)
Explanation:
burning trash doesn’t only allow the waste to go down, it will also produce heat and electricity-while producing less greenhouse gas pollution than burning fossil fuels. However trash fires in burning barrels can smolder and, as a result, produce more harmful chemicals in smoke. Harmful contaminants can also be found in dirt. in conclusion, yes trash does disappear when burned but realeases many harmful chemicals.

D = m / V
D = 108 / 12
D = 9.0 g/cm³
