In general, The more valence electrons a metal has, the stronger its metallic bonds will be because Boron is a metalloid and is ionically bonded.it is too electronegative to release its valence electrons for metallic bonding.As a result, their valence electrons feel a stronger pull from the nucleus (a greater effective nuclear charge) and are less easily released for metallic bonding.
Rainbows go in the order of ROYGBIV, which is an acronym for red, orange, yellow, green, blue, indigo, violet.
So, it would start off with red.
If you want to know why it starts off the rainbow, its because red has the longest wavelength, compared to the rest of the colors. (sorry I'm rambling, I got excited)
Hope this helps.
Answer:
Q = 7.0
Q = kc. The reaction is in equilibrium
Explanation:
Based on the reaction:
Br₂ + Cl₂ ⇄ 2BrCl
Equilibrium constant of the reaction, kc, is the ratio of <em>equilibrium concentrations</em> products over reactants powered to its reaction coefficient:
Kc = [BrCl]² / [Br₂] [Cl₂] = 7.0
Now, reaction quotient, Q, is write as the same Kc but the concentrations are actual concentrations:
Q = [BrCl]² / [Br₂] [Cl₂]
Replacing:
Q = [0.00415M]² / [0.00366M] [0.000672M]
Q = 7.0
Now, as Q = Kc = 7.0, the reaction mixture is in equilibrium
