Answer:
Sharing or covalent bonding is taking place.
Explanation:
The valence electron will be shared by both the atoms so that means that the election will move around both of the atoms.
Many transition metal ions(e.g. in soluble salt solutions) give colored hydroxide precipitates when mixed with aqueous sodium hydroxide solution. However zinc ions give a white hydroxide precipitate. These reactions can be used to help identify transition metal ions in solution.

Answer:
K(70°C) = 2213.376 s-1
Explanation:
balanced reaction:
- NO(g) + O3(g) → NO2(g) + O2(g)
∴ Ea = 63 KJ/mol
∴ A = 8.7 E12 s-1
∴ T = 70°C ≅ 343 K
Arrhenius eq:
∴ R = 8.314 E-3 KJ/K.mol
⇒ K(70°C) = (8.7 E12 s-1)e∧[-(63)/(8.314 E-3)(343)]
⇒ K(70°C) = (8.7 E12 s-1)*(2.5444 E-10)
⇒ K(70°C) = 2213.376 s-1

This is a guess, but I think it could be the lack of limiting factors.
