30.0L of helium gas into moles of helium gas.​
zepelin [54]
<h3>Answer:</h3>

1.25 moles (R.T.P.) or 1.34 moles (S.T.P.)

<h3>Explanation:</h3>
  • 1 mole of a gas occupies a volume of 24 liters at room temperature and pressure (R.T.P.)
  • On the other hand, 1 mole of a gas will occupy 22.4 Liters at standard temperature and pressure (S.T.P.)

Therefore, at R.T.P.

30.0 Liters will be equivalent to;

= 30.0 L ÷ 24 L

= 1.25 moles

At S.T.P

30.0 Liters will be equivalent to;

= 30.0 L ÷ 22.4 L

= 1.34 moles

Thus, 30.0 L of helium gas are equivalent to 1.25 moles of He at R.T.P. and 1.34 moles at S.T.P.

Which chemical in the atmosphere of Titan (a moon of Saturn) plays the same role that water plays on the Earth by producing "rai
ololo11 [35]

Answer:

Methane (CH₄)

Explanation:

Titan refers to the largest moon of the planet Saturn, comprising a very dense atmosphere. This moon is primarily comprised of nitrogen gas, which is similar to the conditions in earth. It is extremely cold having a temperature of about ₋180°C, as a result of which it is difficult for the liquid water to exist.

Acid rain is a type of precipitation that occurs in the earth and it results in the release of a certain amount of methane gas (CH₄). Similarly, there also occurs precipitation in Titan but it releases CH₄ instead of water.  This methane is responsible for the increasing amount of temperature.

Thus, methane is a chemical that is present int the Titan's atmosphere, and it plays a similar role as in earth, the water plays by forming snow, rain, and ice.
