Answer:
V₂ = 145.35 L
Explanation:
Given data:
Initial volume = 400 L
Initial pressure = 300 mmHg (300/760 =0.39 atm)
Initial temperature = 20 °C (20 +273 = 293 K)
Final temperature = 273 K
Final volume = ?
Final pressure = 1 atm
Solution:
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
P₁V₁/T₁ = P₂V₂/T₂
V₂ = P₁V₁T₂ /T₁ P₂
V₂ = 0.39 atm × 400 L × 273 K / 293 K × 1 atm
V₂ = 42588 atm.L.K /293 K.atm
V₂ = 145.35 L
Answer:
D. association with bacterial species.
Explanation:
Methanogens -
These are the organisms , that falls under the category of the prokaryotes , in the domain archaea .
Methanogens are a type of microorganism , which is capable to produce methane as one of the by product during a hypoxic condition .
These organisms are found in the wetland , inside the digestive system of the humans and animals .
They have an important space for the treatment of the anaerobic wastewater .
Hence , from the question ,
The correct option is d.
Answer:
D
Explanation:
The potential energy curve of a system of atoms define the potential energy of the atoms with respect to the inter-nuclear separation. The minimum point of the curve represents the equilibrium bond length of the bond.
The energy of the system depends on the distance between the two interacting atoms.
Looking at the potential energy curve for hydrogen molecule in option D, we can assert that a chemical bond indeed exists between the two atoms of hydrogen and the minimum point of the curve is the equilibrium bond length of the bond.
