The thermal energy will flow from the hotter object to the cooler object until their temperatures are equal i.e. until they reach equilibrium.
Answer:
D. equilibrium
Answer is: Ksp for strontium arsenate is 2.69·10⁻¹⁸.
Balanced chemical reaction (dissociation):
Sr₃(AsO₄)₂(s) → 3Sr²⁺(aq) + AsO₄³⁻(aq).
s(Sr₃(AsO₄)₂) = 0.0650 g/L.
s(Sr₃(AsO₄)₂) = 0.0650 g/L ÷ 540.7 g/mol = 1.2·10⁻⁴ mol/L.
s(Sr²⁺) = 3s(Sr₃(AsO₄)₂).
s(AsO₄³⁻) = 2s(Sr₃(AsO₄)₂).
Ksp = s(Sr²⁺)³ · s(AsO₄³⁻)².
Ksp = (3s)³ · (2s)².
Ksp = 108s⁵.
Ksp = 108 · (1.2·10⁻⁴ mol/L)⁵ = 2.69·10⁻¹⁸.
The original change is chemical, affecting the main colorant because of temperature. Paint, is a surface change, not changing anything about the leaf itself, but showing a different color to your eye.
Hey there!
The correct answer should be B. Potential Energy Only
Potential energy is the energy stored in an object because it isn’t moving/isn’t in motion
Hope this helps you!
