3) electronegativity difference
Explanation:
The degree of polarity of a bond is indicated by the electronegativity difference between the atoms that forms the bond.
Electronegativity is the of atoms in a bond to attract the valence electrons in chemical bond more closely to themselves.
- An atom with a high electronegative value often pulls the electron to itself more.
- If the elecronegativity difference between the two species is between 0.4 and 1.7, they are polar covalent bonds.
- If is is greater than 1.7, they are ionic bonds.
- If less than 0.4, then a non-polar covalent bond must have formed.

Answer:
The answer is b, c, d, e
Explanation:
b. 2 N2O5 → 4 NO2 + O2
r = k [N2O5]^2 --> Second-order regarding global reaction
c. 2 HI → H2 + I2
r = k [HI]^2 --> Second-order regarding global reaction
d. 2 N2O → 2 N2 + O2
r = k [N2O]^2 --> Second-order regarding global reaction
e. 2 NO2 → 2 NO + O2
r = k [NO2]^2 --> Second-order regarding global reaction
1. an alpha particle
gamma rays are formally massless, positrons and electrons (beta particles) have negligible mass, but alpha particles have about 4 amu of mass
The corrects answer is 259 K
The correct answer is freezing point
