Answer:
"Potassium hydroxide is basic while aqueous ammonia is acidic.
KOH has a pH of more than 7, while aqueous NH3 has a pH of less than 7."
Explanation:
Answer:
A. ΔS°rxn decreases
B. ΔS°rxn decreases
C. ΔS°rxn has little or no change
D. ΔS°rxn increases
Explanation:
The change in entropy (ΔS°rxn) is related to the change in the number of moles of gases (Δn(gas) = n(gas products) - n(gas reactants)). If the number of moles of gases increases, there are more possible microstates and entropy increases. The opposite happens when there are less gaseous moles. And little or no change in entropy is expected when the number of moles of reactants and products is the same.
<em>A. K(s) + O₂(g) ⟶ KO₂(s)</em>
Δn(gas) = 0 - 1 = -1
ΔS°rxn decreases
<em>B. CO(g)+ 3 H₂(g) ⟶ CH₄(g) + H₂O(g)</em>
Δn(gas) = 2 - 4 = -2
ΔS°rxn decreases
<em>C. CH₄(g) + 2 O₂(g) ⟶ CO₂(g)+ 2 H₂O(g)</em>
Δn(gas) = 3 - 3 = 0
ΔS°rxn has little or no change
D. N₂O₄(g) ⟶ 2 NO(g) + O₂(g)
Δn(gas) = 3 - 1 = 2
ΔS°rxn increases
I think B would be the right answer, because knowing the feedback of results of the insecticide would give you more knowledge on which one would be less dangerous for animals and children.
The person above above above me is very very good awnswer hope this helps
