What is the bond order of c2−?express the bond order numerically?

diamong [38]

MO Diagram of C₂⁻ is shown below,

Bond order is calculated as,

Bond Order = [# of e⁻s in BMO]-[#of e⁻s in ABMO] / 2
Where,

BMO = Bonding Molecular Orbital

ABMO = Anti-Bonding Molecular Orbital

Putting values,

Bond Order  =  [9]-[4] / 2

Bond Order  =  5 / 2

Bond Order  =  2.5

A sample of seawater contains 1.3 g of calcium ions in 3,100 kg of solution. what is the calcium ion concentration of this solut

IrinaVladis [17]

A unit of ppm has an acronym of parts per million. The equivalent units of ppm is therefore mg/L and mg/kg. So the ppm is:

mass Ca+ = 1.3 g = 1300 mg

ppm = 1300 mg / 3100 kg

ppm = 0.42 ppm
