1.) Gas given off
2.) precipitate formed
3.) large amount of heat given off
4.) Color change
There are 0.501 moles in 60.66g of CF2Cl2
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
Answer: [D]: "They are not part of the rock cycle." .
