Metals, non-metal and noble gases are the three categories useful for classifying the elements in periodic table.

<u>Explanation:</u>

Elements are defined as a vertical group and a horizontal period in periodic table. Metals, non-metal and noble gases are the three categories useful for classifying the elements in periodic table.

A large number of elements in periodic table flow under the Metals category. Non-metal in the table are mostly gaseous. Noble gases in the table are colorless and non-reactive.

who brought astronomy out of the dark ages by declaring: "finally we shall place the sun himself at the center of the universe.
solong [7]

Nicolaus Copernicus was the one who brought astronomy out of the dark ages.

In one of his books "On the Revolutions of the Heavenly Bodies", he published the renowned line which declares his theory.

Nicolaus Copernicus, A polish astronomer put forward the theory that the is th Sun one that rests in the middle or center of the Universe and the planet Earth revolves around it on its axis every day.which was considered to be called the Heliocentric system.

A sample of argon gas (molar mass 40 g) is at four times the absolute temperature of a sample of hydrogen gas (molar mass 2 g).
qaws [65]

To solve this problem, let us recall that the formula for gases assuming ideal behaviour is given as:

rms = sqrt (3 R T / M)

where

R = gas constant = 8.314 Pa m^3 / mol K

T = temperature

M = molar mass

Now we get the ratios of rms of Argon (1) to hydrogen (2):

rms1 / rms2 = sqrt (3 R T1 / M1) / sqrt (3 R T2 / M2)

or

rms1 / rms2 = sqrt ((T1 / M1) / (T2 / M2))

rms1 / rms2 = sqrt (T1 M2 / T2 M1)

Since T1 = 4 T2

rms1 / rms2 = sqrt (4 T2 M2 / T2 M1)

rms1 / rms2 = sqrt (4 M2 / M1)

and M2 = 2 while M1 = 40

rms1 / rms2 = sqrt (4 * 2 / 40)

rms1 / rms2 = 0.447

 

Therefore the ratio of rms is:

<span>rms_Argon / rms_Hydrogen = 0.45</span>
