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
What words are you looking for so i dont put them down
Chlorobenzene would essentially be a benzene ring that is substituted with chlorine. Thus it would have 6 carbon atoms, in its molecular formula.
A) number of neutrons in the nucleus... all isotopes of an element contain the same number of protons which is equal to that elements atomic number...
hope this helps!
Hydrogen Gas is an element. Hydrogen gas was first produce on the 16th century and it was odorless, colorless, nonmetallic, tasteless, highly flammable diatomic gas with the molecular formula H2. It also used to produced ammonia for agricultural fertiliser (the Haber process) and also methanol and cyclohexane.
