Answer:
here is a diagram of Bohr's sulfur.
I'm assuming it would be ocean warming?
What are the options given?
The equation representing the decomposition of BaCO₃ is as follow:
BaCO₃(s) ⇄ BaO(s) + CO₂(g)
Standard Gibbs-free energy (ΔG⁰) = 220 kJ/mol
Gas constant (R) = 8.314 x 10⁻³ kJ/K.mol
Temperature (T) =25 + 273 = 298 K
ΔG⁰ = - R T lnK
ln K = - ΔG⁰ / RT = - 88.8
K =
= 2.7 x 10⁻³⁹
So the equilibrium constant of the reaction at 298 K is 2.7 x 10⁻³⁹
From the equation:
Equilibrium constant Kp = Pco₂
= 2.7 x 10⁻³⁹ atm
Answer:
Option 2:
The warmth of the spoon is conducted to the ice cream making it easier to scoop out.
Explanation:
Conduction refers to the transfer of heat from a hotter body to a cooler one, by virtue of physical contact between the two bodies. This is opposed to radiation, where there does not need to be any contact between the two bodies before heat con flow.
The warm spoon, once it has physical contact with the cool ice cream, it loses some of its heat to the ice cream, warming it up, making it easier to scoop up.
