Consider two gaseous systems: one for which the Vrms of the particles is low and another for which the Vrms of the particles is high. What can you say about the relative temperatures of

each system?

See explanation

Explanation:

According to chemistry libretexts(2020); "The rms velocity is directly proportional to the square root of temperature and inversely proportional to the square root of molar mass. Thus quadrupling the temperature of a given gas doubles the rms velocity of the molecules. ... As the temperature of a gas is increased, the velocity of the molecules is also increased."

Hence considering two gases for which the  Vrms of the particles of one is high and that of the other is low, we can conclude that the gas having the higher  Vrms is at a higher temperature than the gas having a lower  Vrms according to the foregoing.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
