Answer:
Krypton is named after the Greek word that means "secret." Which explains why krypton was most likely given this name? Krypton is a noble gas, so it was difficult for chemists to find it, as though it was a secret.

<span>6.37x10^-30 coulomb-meters
The unit for dipole moments is the Debye which is 1x10^-21 C*m^2/s divided by the speed of light (299792458 m/s). So the conversion factor is
1x10^-21 C*m^2/s / 299792458 m/s = 3.33564095E-30 C*m
And converting 1.91 d to Cm gives
1.91 * 3.33564095E-30 C*m = 6.37x10^-30 coulomb-meters</span>
Answer:
cinnamic acid - 150 mg
cis-stilbene - 100 μL
trans- stilbene - 100 mg
pyridinium tribromide - 200-385 mg
For this data:
moles of cinnamic acid = 0.150 g/148.16 g/mol = 0.001 mols
Theoretical mass of dibromoproduct formed = 0.001 mol x 307.97 g/mol = 0.312 g
cis-stilbene (100 ul = 0.1 ml)
moles of cis-stilbene = 0.1 ml x 1.01 g/mol/180.25 g/mol = 0.00056 mols
Theoretical mass of dibromoproduct formed = 0.00056 mol x 340.05 g/mol = 0.19 g
trans-stilbene
moles of tran-stilbene = 0.1 g/180.25 g/mol = 0.00055 mols
Theoretical mass of dibromoproduct formed = 0.00055 mol x 340.05 g/mol = 0.19 g
