Answer:

<u>The two different celestial bodies:</u>

There about eight planets inside the solar system, as the different planets and stars hold greater significance inside the system when it comes to there position inside the solar system. While, the distances of the planets from the Sun inside the solar system also plays a great value and holds different properties with respect to each other.

  • Mercury is considered as the planet which is the most closest of all the planets to the sun inside the solar system. As it gains more amount of energy, resulting from a higher level of exposure to the Sun's ultraviolet rays. Now, the temperature,T of the planet is far much higher then any other planet inside the solar system, just because its surface receives the much high level of UV lights from the red giant.Mars is far hot for any living life to spend on it, as the planet lacks any back up for the objects to shield itself from any foreign entities or any amount of energy.
  • While, the Earth is far away from the Sun to receive the optimum level of heat from the Star inside the solar system. As earth has much distance to cover for the sunlight to reach it. Along, with which the Earth has a set of layers to shield itself from any Ultra violet rays coming from the star in the middle of the solar system. The temperatures,T value of the Earth is far less and is able to sustain life on the planet. And that is also due to the balance formed of energy,E levels in the layers of the planet.

The difference would be that Mercury has a denser, warmer atmosphere and Earth has a not that dense and gassy atmosphere. The Earth's atmosphere also has a lot of layers while Mercury's doesn't. Those would be the reasons for them both being different. Hope this helped!

What is the index of hydrogen deficiency of a compound with a molecular formula of c6h15n?
7nadin3 [17]

Answer:

IHD = 0

Explanation:

Given that

C₆H₁₅N

Number of carbon atoms(n) = 6

Number of hydrogen atoms(x') = 15

Number of nitrogen atoms = 1

There is nitrogen atoms then x = x' -1

The index of hydrogen deficiency given as

IHD=\dfrac{2n+2-x}{2}

So

IHD=\dfrac{2n+2-x}{2}

IHD=\dfrac{2\time 6+2-(15-1)}{2}

IHD = 0

The index of hydrogen deficiency is zero.

What temperature would 3.54 moles of xenon gas need to reach to exert a pressure of 1.57 atm at a volume of 34.6 l
ira [324]

Answer:

186.9Kelvin

Explanation:

The ideal gas law equation is PV = n R T

where

P   is the pressure of the gas

V   is the volume it occupies

n  is the number of moles of gas present in the sample

R  is the universal gas constant, equal to  0.0821 atm L /mol K

T  is the absolute temperature of the gas

Ensure units of the volume, pressure, and temperature of the gas correspond to R ( the universal gas constant, equal to  0.0821 atm L /mol K )

n = 3.54moles

P= 1.57

V= 34.6

T=?

PV = n R T

PV/nR = T

1.57 x 34.6/3.54 x 0.0821

54.322/0.290634= 186.908620464= T

186.9Kelvin ( approximately to 1 decimal place)
