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.

What occurs when energy is removed from a liquid-vapor system in equilibrium
yulyashka [42]

<span>The answer is that the number of water molecules  increases and that of vapor decreases.  When energy is removed from the system it would do so mostly as heat. Therefore the energy in the system would decrease and the molecules would vibrate at lower energies. Therefore, several water vapor molecules would turn back to water.  </span>

Alika [10]

Answer:

Explanation:

Cadmium:(Cd)

Cadmium is transition metal present in group twelve. It is soft metal and properties are similar to the other group members like zinc and mercury. Its atomic number is forty eight and have two valance electrons.

Electronic configuration:

Cd₄₈ = [Kr] 4d¹⁰ 5s²

Vanadium: (V)

It is present in group five. It is malleable and ductile transition metal. Its atomic number is twenty three. Vanadium have five valance electrons.

Electronic configuration:

V₂₃ =[Ar] 3d³ 4s²

Xenon: Xe

Xenon is present in group eighteen. It is noble gas. Its outer most valance shell is complete that's why it is inert. its atomic number is fifty four. Xenon have eight valance electrons.

Electronic configuration:

Xe₅₄ = [Kr] 4d¹⁰ 5s² 5p⁶

Iodine: (I)

Iodine is present in group seventeen. Its outer most valance shell have seven electrons. Iodine is the member of halogen family. It gain one electron to complete the octet. its atomic number is fifty three.

Electronic configuration:

I₅₃ = [Kr] 4d¹⁰ 5s² 5p⁵

Potassium: (K)

Potassium is present in group one. it is alkali metal. Its atomic number is nineteen. Its valance shell has one electron. Potassium loses its one valance electron and gets stable electronic configuration.

Electronic configuration:

K₁₉ = [Ar] 4s¹

Strontium: Sr

Strontium is present in group two. it is alkaline earth metal. its atomic number is thirty eight and have two valance electrons.

Electronic configuration:

Sr₃₈ = [Kr] 5s²
