The mass of 2.0 x 10-5 moles of uranium is 4.8 x 10-3 grams.

The molar mass of a substance is the mass of 1 mole of the substance.

The molar mass of uranium is 238 g.

This is the mass of 1 mole of uranium.

The mass of 2.0 x 10-5 moles of uranium = 238 g × 2.0 x 10-5

The mass of 2.0 x 10-5 moles of uranium = 0.00476 g = 4.8 x 10-3 grams

Therefore, the mass of 2.0 x 10-5 moles of uranium is 4.8 x 10-3 grams.

Answer:

Melting ice causes more warming.

Because they are darker in color, the ocean and land absorb more incoming solar radiation, and then release the heat to the atmosphere. This causes more global warming. In this way, melting ice causes more warming and so more ice melts.

Explanation:

Geologic erosion influences soil formation and distribution. Accelerated erosion results from the removal of natural vegetation by human activities such as farming, ranching, forestry, and construction. The production of agricultural and forest products can be affected by excessive erosion

Answer:

75%

Explanation:

percent yield is the actual yield divided by the theoretical (predicted) yield, then multiplied by 100 to get a percentage.

60/80 = 0.75

0.75 x 100 = 75%

Answer:

33.34 %

Explanation:

Given that,

Actual yield = 60 g

Theoretical yield = 80 g

We need to find the percentage yield. It can be calculated as follows :

[tex]\%=\dfrac{Acutal-theoretical }{Actual}\times 100\\\\=\dfrac{60-80}{60}\times 100\\\\=33.34\%[/tex]

So, the required percentage yield is 33.34 %.

Answer:

no so boring........................

A square hot air balloon would be hard to make because the round shape of traditional hot air balloons allows for even distribution of heat, which is necessary to maintain the balloon's lift and stability.

A hot air balloon is a balloon filled a heated air which can rise above the atmosphere. In a round balloon, the heat from the burner is evenly distributed around the circumference of the balloon, causing the air inside to heat up and rise, which in turn causes the balloon to lift.

If a hot air balloon were to be made in a square shape, the heat would be distributed unevenly and concentrated in certain areas. This could cause the balloon to become unstable, as the hot air would rise in some areas but not others, leading to uneven lifting and potential loss of control.

Additionally, the corners of the square shape would be more susceptible to damage and could create weak points in the structure of the balloon.

Therefore, while it is possible to create hot air balloons in other shapes, the traditional round shape has been found to be the most effective and efficient for maintaining the necessary heat distribution and stability required for safe and successful flight.

Answer:

The final volume of the balloon is 24.480 liters.

Explanation:

Let consider that no leakages occur in the balloon during the isobaric process and that helium behaves ideally. From Equation of State for Ideal Gases, we construct the following relationship:

[tex]V_{o}\cdot T_{o} = V_{f}\cdot T_{f}[/tex] (1)

Where:

[tex]V_{o}[/tex], [tex]V_{f}[/tex] - Initial and final volume, measured in liters.

[tex]T_{o}[/tex], [tex]T_{f}[/tex] - Initial and final temperature, measured in Kelvin.

If we know that [tex]V_{o} = 30\,L[/tex], [tex]T_{o} = 288.15\,K[/tex] and [tex]T_{f} = 353.13\,K[/tex], the final volume of the balloon is:

[tex]V_{f} = \frac{V_{o}\cdot T_{o}}{T_{f}}[/tex]

[tex]V_{f} = 24.480\,L[/tex]

The final volume of the balloon is 24.480 liters.

Answer:

it compresses under the pressure.

Explanation:

when she comes up, it will re-expand as pressure goes down- this is why they have to be very careful how fast they come back up.

Answer:

If a diver goes through too great of pressure change too quickly, their body cannot eliminate all of the expanding nitrogen and the excess nitrogen forms bubbles in their tissues and blood. These nitrogen bubbles can cause decompression sickness (DCS) by blocking blood flow to various parts of the body, causing strokes, paralysis, and other life-threatening problems.
