Ahydrogen molecule (diameter 1.38 × 10-8 cm), traveling at the rms speed, escapes from a 4200 k furnace into a chamber containing cold argon atoms (diameter 3.43 × 10-8 cm) at a density of 4.43 × 1019 atoms/cm3(a) what is the speed of the hydrogen molecule

The speed of hydrogen molecule is

Explanation:

The equation used to calculate the root mean square speed of a molecule is:

where,

= root mean square speed of the molecule = ?

R = Gas constant = 8.314 J/mol.K

T = temperature = 4200 K

M = molar mass of hydrogen molecule =   (Conversion factor:  1 kg = 1000 g)

Putting values in above equation, we get:

Hence, the speed of hydrogen molecule is

they emit helium gas that attaches to nearby planets.

they remove low-mass elements from the planets’ crust.

they cause nuclear fusion inside the inner core of planets.

they produce heavy elements such as iron and gold.

i think it's c. i'm not sure but i think so.
