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
Villi are tiny finger like projections present in the inner epithelial lining of the intestine. Each finger like villi is further divided into microvilli, which is the extension of plasma membrane of each epithelial cell of the villi. These villi and microvilli present on the inner surface of the intestine provide a greater surface area and this enhances the digestion and absorption of the nutrients.
Therefore, the correct answer is false as a microvilli is the tiny finger like projection of the inner epithelial cells of the small intestine that has absorptive functions.
Mass is required for gravity. Higher mass implies higher gravitational drag. Most of these thoughts are tied to other planets without atmospheres, or the moon. The moon doesn't have any air or atmosphere and it pulls the Earth water.
Please correct any mistakes in my answer!! I'd be happy to fix it!! :)
<span> The formula for </span>measuring<span> density is Density = </span>Mass/Volume<span>, or D=M/V. The / means “per” or “for each,” which in math is the same as “divided by.”</span>
Answer:
I think these are it
Explanation:
The amount of current is the same at every point in a series circuit.
All of the parts of a series circuit—power source, wires, and devices—are connected along the same pathway
If one device in a series circuit burns out or is disconnected, the entire circuit is broken
The electrons have multiple pathways to travel.
Each time there is damage (break) in any one of the resistors the entire circuit will not function.
