Nitrogen monoxide and bromine react to form nitrosyl bromide according to the following equation 2NO (g) + Br2 (g) <=> 2NOBr (g)

Use the given data to find equilibrium constant expression

[NOBr] = 0.0474 mol/L, [NO] = 0.312 mol/L, [Br2] = 0.259 mol/l

well off of my head we know that the perfume bottle is most likely opened, or broken. i can also tell it is moving at low and high concentration because it is covering the other side of the room. what we can obtain from this information is it explains why the odor can be detected at the other side of the room.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

the answer for sodium is 0.186
