The effective speed (rms) of the oxygen gas is 293.68 m/s.

<h3></h3><h3>What is Root-mean-square velocity?</h3>

Root mean square velocity is the square root of the mean of squares of the velocity of individual gas molecules

v_{rms}=\sqrt[]{\frac{3RT}{M} }

<em>where </em>R = universal gas constant

M = molar mass of the gas in kg/mol

T = temperature in Kelvin

According to the ideal gas law,

PV = nRT

RT = \frac{PV}{n}

Substitute in the rms velocity formula,

v_{rms} = \sqrt[]{\frac{3PV}{nM} }

P = 92 kPa, V = 10 L, n = 2 moles and M = 32 x 10⁻³ kg/mol

v_{rms} = \sqrt[]{\frac{3\times92\times10}{2\times32\times10^-^3} }

=293.68 m/s

Thus, the effective speed (rms) of O₂ gas is 293.68 m/s.

Answer:

  1. atomic #= 1
  • protons equals one
  • Number of neutrons equals to 0
  • number of electrons equal to 1
  • mass number equals to 1

2.

  • atomic number equals to 1
  • Protons equals to 1
  • number of neutrons equals to 0
  • number of electrons equals to 0 because the plus sign means that it loses an electron
  • mass number equals to 1

3.

  • atomic number 17
  • number of protons 17
  • number of neutrons 18
  • number for electrons 18 Because negative sign means It's an anion which means it gains an electron
  • mass number 35

4.

  • 12
  • 12
  • 12
  • 10 loses 2 its a cation
  • 24

5.

  • 47
  • 47
  • 108-47 = 61
  • 46 loses 1
  • 108

6.

  • 16
  • 16
  • 32-16 =16
  • 18 it gains 2 electrons
  • 32
