Question

12/15 convert into per%
with calculation​

Answer 1

Answer:

Step-by-step explanation:1 According to Dalton's law of partial pressure:

Moles of Nitrogen = 2855=1.964

Moles of Oxygen = 3220=0.625

Moles of CO2=4425=0.568

Total moles = 3.157

P′=mole fraction×PM

PN2=3.1571.964×760=472.8 mm

PO2=3.1570.625×760=150.4 mm

PN2=3.1570.568×760=136.7 mm

The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length.

so, we know how to calculate the bond order….actually let me just show it

(B.O)=1/2[(no of electron in anti bonding MO)-(no.of electrons in bonding MO)]

for, O2 : BO=1/2[10–6]=2

for, O2- : BO=1/2[10–7]=1.5

for, O2+ : BO=1/2[10–5]=2.5

for, O2^–2 : BO=1/2[10–8]=1

for, O2^+2 :BO=[same as N2]=3

So, the increasing sequence bond order

O2^-2 < O2- < O2 < O2+ < O2^+2

therefore, the increasing order of bond length of these species is,

O2^+2 < O2+ < O2 < O2 < O2^-2
