Explanation:
It stays roughly the same size. Electrons have a barely imperceptible mass so the overall mass of the atom is changed very little.
A. Magnetic force is an non-contact force
Answer:
b. - 184 J/K
Explanation:
- ΔSsurr = - ΔH/T....at constant P and T.
∴ ΔHrxn = 54.2 KJ = 54200 J
∴ T = 25°C ≅ 298.15 K
⇒ ΔSsurr = - (54200 J)/(298 K)
⇒ ΔSsurr = - 182 J/K ≅ - 184 J/K
