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
H is positive 1 and o is negative 2 so 3+b-6=0 and solve for b to get b=3
Question 24 is 56 because the nuetrons don't have weight
Inert gases are also called noble gases. They are the elements found in Group 8A in the periodic table. They are inert because they don't react with other elements. This is because they have the most stable electronic configuration. That's why elements form ions to gain or give way electrons so that they conform with the electronic configuration of the nearest inert gas. Basing on the periodic table, the nearest inert gas to K is Argon. The nearest inert gas to I is Xenon.
