As the name implies, anaerobic means there is no presence of oxygen. So if it will take place, it will only take place in little or no oxygen which is in the last sentence in the following choices. First and second choice are wrong for there is a need of oxygen required when there is no oxygen is needed and the presence of nitrogen in water.
Answer:
Explanation:
The nuclear model of the atom was suggested by Ernest Rutherford based on his experiment on a thin gold foil.
To explain his observations, he suggested the atomic or nuclear model.
In this model, the atom has a small positively charged center called the nucleus.
All the mass of the atom is concentrated here in the nucleus.
Surrounding the nucleus is a large space
It is the extranuclear part
This part contains electrons.
A nucleus surrounded by electrons forms the nuclear model of the atom.
Answer:
The answer will be...
B.) skeleton
C.) impenetrable coating
E.) protection
Explanation:
The cell wall provides the cell with both structural support and protection, and also acts as a filtering mechanism.

Answer:
The vapor pressure of benzaldehyde at 61.5 °C is 70691.73 torr.
Explanation:
- To solve this problem, we use Clausius Clapeyron equation: ln(P₁/P₂) = (ΔHvap / R) (1/T₁ - 1/T₂).
- The first case: P₁ = 1 atm = 760 torr and T₁ = 451.0 K.
- The second case: P₂ = <em>??? needed to be calculated</em> and T₂ = 61.5 °C = 334.5 K.
- ΔHvap = 48.8 KJ/mole = 48.8 x 10³ J/mole and R = 8.314 J/mole.K.
- Now, ln(P₁/P₂) = (ΔHvap / R) (1/T₁ - 1/T₂)
- ln(760 torr /P₂) = (48.8 x 10³ J/mole / 8.314 J/mole.K) (1/451 K - 1/334.5 K)
- ln(760 torr /P₂) = (5869.62) (-7.722 x 10⁻⁴) = -4.53.
- (760 torr /P₂) = 0.01075
- Then, P₂ = (760 torr) / (0.01075) = 70691.73 torr.
So, The vapor pressure of benzaldehyde at 61.5 °C is 70691.73 torr.
