Hydrogen and helium are the lightest elements in the periodic table.

<h3>What is helium and hydrogen made of?</h3>
  • Hydrogen and helium are uniformly mixed and form a layer on the surface of gas giants.
  • Scientists predicted in the 1970s that the two lightest elements might separate and form a region of demixing or immiscibility at the high temperatures and pressures found inside gas giants.
  • They are the two most prevalent elements in the universe and are gases at room temperature, with hydrogen constituting roughly 75% of all matter.
  • A helium atom consists of a nucleus with two neutrons and two positively charged protons, which is surrounded by two negatively charged electrons in orbit.
  • One proton and one electron make up one hydrogen atom.

translational = 3

rotational = 2

vibrational = 1

Total = 6

Internal energy = 6N  x 1 /2 k T where N is no of molecules

E₁ = 3 N kT

At the temperature of 1000K , helium  will have following degree of freedom

translational = 3

rotational = 0

vibrational =  0

Total = 3

Internal energy = 3N  x 1 /2 k T where N is no of molecules

E₂ = 3 / 2 N kT

Ratio =  E₁ / E₂

=  2

Which symbol can be used to indicate a chemical reaction that takes place in the presence of a catalyst? mc032-1. Jpg mc032-2. J
lys-0071 [83]

The catalyst has been represented with the formula above the arrow in the chemical equation.

The catalyst has been the compound or element in the chemical reaction that helps in the lowering of the activation energy of the system and thereby leads to an increase in the rate of the reaction.

The chemical equation has been represented in the form of the chemical formula of the reactants and the products.

The catalyst has not been consumed in the chemical reaction, thus it has been represented with the formula above the arrow in the chemical equation.

For more information about the catalyst, refer to the link:
