Answer:
The Deeper these nodules are, the harder it becomes. To use robotic submersibles eliminates the need for oxygen for people, but they would need an especially designed loader or mechanical “hands” to gather, and Balloons could Raise the mined Mn to the surface for collection.

The patient should be given 285.71 ml.
1000 ml contains 70 gr glucose.
x contains 20 gr glucose.
x=1000*20/70
Answer:
No
Explanation:
The gas will have more volume compared to the liquid.
Gases have no definite shape and no volume. They simply assume the shape of any container they are placed into. They will fill up the entirety of the bottle they are placed into.
Liquids have fixed volume although they do not have fixed shape. As they are held with weak intermolecular interactions, they are limited in space.
Therefore, they will maintain that initial volume at which they were introduced into the container.
- Liquids generally have a fixed volume and gases do not.
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.
