The molar mass of a gas that moves 1.25 times as fast as CO2 is 28.16 g.

<h3>Molar mass of the gas</h3>

The molar mass of the gas is determined by applying Graham's law of diffusion.

R₁√M₁ = R₂√M₂

R₁/R₂ = √M₂/√M₁

R₁/R₂ = √(M₂/M₁)

where;

  • R₁ is rate of the CO2 gas
  • M₁ is  molar mass of CO2 gas
  • R₂ is rate of the second gas
  • M₂ is the molar mass of the second gas

R₁/1.25R₁ = √(M₂/44)

1/1.25 =  √(M₂/44)

0.8 = √(M₂/44)

0.8² = M₂/44

M₂ = 0.8² x 44

M₂ = 28.16 g

Thus, the molar mass of a gas that moves 1.25 times as fast as CO2 is 28.16 g.

Which metals have similar chemical property’s? Check all that apply.
Rudik [331]

Barium, Beryllium, Radium, and Calcium.

<h3>Explanation</h3>

All four metal elements (Ba, Be, Ra, and Ca) are found in group 2 of a modern periodic table. By periodicity, they have similar chemical properties.

Shared properties likely include:

  • Softness. With only two valence electrons per atom, the four elements form weak metallic bonds. Their pure forms are thus easy to shape and cut.
  • High reactivity. Group 2 "alkaline-earth" metals are only two electrons away from ideal gas electron configurations. They lose electrons more readily than most transition metals such as iron and copper do. Group 2 metals tarnish easily in the earth atmosphere, and reacts readily with water to produce hydrogen and a base- hence the name "alkaline."

How does the size change when an atom forms a cation and when an atom forms an anion?
mario62 [17]
<span>A cation is an atom that loses a valence electron. When a valence electron is released there is one electron less to create a repulsive force. The loss of a repulsive force will allow the atom to pull tighter together. An anion would therefore be larger in size due to increased repulsion of the valence electrons.</span>
