Answer:
The molecules in the water become more separated due to heat.
Ans: The entropy change for the given reaction is 93.3 J/K
Given reaction:
Br2(l) → Br2(g)
ΔS = ∑n(products)S⁰(products) - ∑n(reactants)S⁰(reactants)
= 1 mole* S°(Br2(g)) - 1 mole*S°(Br2(l))
= 1 mole *245.5 J/mol-K - 1 mole*152.2 J/mol-K
= 93.3 J/K
Graphite is a not metal because of the lack of the properties
- Metals are ductile but graphite is not ductile
- Metals are meleable but graphite is not meleable
- metal are sonorous but. graphite is not sonorous
- Metal are lustrous but graphite is not lustrous
Graphite contains only one property of metal
- metal is a good conductor of electricity but its a exception.
Because of all that reasons graphite is not included in metalloid.
Hope it helps u mate
