Consider the equilibrium describing the endothermic dissolution of a solid in water. Z n ( o h ) 2 ( s ) − ⇀ ↽ − z n 2 + ( a q ) + 2 o h − ( a q ) if you have a saturated solution at equilibrium, what changes could you make to increase the solubility of the compound?.
To drive this equilibrium in the forward direction, for a saturated solution, the temperature of the system must be increased.
We have been told that the reaction; Zn(OH)2 ( s ) ⇄ Zn2+(aq) + 2OH − (aq), is an endothermic reaction. Recall that in an endothermic reaction, energy is absorbed and the energy of the products is greater than that of the reactants.
In order to drive this equilibrium in the forward direction, for a saturated solution, we can Increase the temperature of the solution. More Zn(OH)2 will dissolve in the solution.

A tube is being stretched while maintaining its cylindrical shape.
Answer:
This question is incomplete, the complete question is;
A tube is being stretched while maintaining its cylindrical shape. The height is increasing at the rate of 2 millimeters per second. At the instant that the radius of the tube is 6 millimeters, the volume is increasing at the rate of 96π cubic millimeters per second. Which of the following statements about the surface area of the tube is true at this instant? (The volume V of a cylinder with radius r and height h is V=πr2h. The surface area Sof a cylinder, not including the top and bottom of the cylinder, is S=2πrh.)
A) The surface area is increasing at the rate of 28pi square mm per second.
B) The surface area is decreasing at the rate of 28pi square mm per second.
C) The surface area is increasing at the rate if 32pi square mm per second.
D) The surface area is decreasing at the rate of 32pi square mm per second.
Answer:
Surface Area is increasing at the rate of 28π mm²/sec ( Option A )
Explanation:
Given the data in the question;
let r be the radius and h be the height of the tube
so volume V = πr²h
dv/dt = πr² dh/dt + 2nrh dr/dt
⇒ 96n = π × 36 × 2 + 2π × 6h dr/dt
⇒ 24π = 12nh dr/dt ⇒ h.dr/dt = 2
Area Surface S = 2nrh
ds/dt = 2π ( r.dh/dt + h.dr/dt )
= 2π ( 6×2 + 2)
= 2π (14)
= 28π
therefore Surface Area is increasing at the rate of 28π mm²/sec ( Option A )

A hemisphere of radius 8 sits on a horizontal plane. A cylinder stands with its axis vertical, the center of its base at the center of the sphere, and its top circular rim touching the hemisphere. Find the radius and height of the cylinder of maximum volume.
The dimensions of the cylinder that has the maximum volume can be
found be finding the maximum value of the volume function.
[tex]\mathrm{The \ \underline{height \ of \ the \ cylinder \ of \ maximum \ volume \ is \ \dfrac{8}{\sqrt{3} }}}[/tex][tex]\mathrm{The \ \underline{radius \ of \ the \ cylinder \ of \ maximum \ volume \ is \ \dfrac{8 \cdot \sqrt{6} }{3}}}[/tex]Reasons:
The known parameter of the hemisphere are;
The radius of the hemisphere = 8
Required;
The radius and height of the maximum volume of the inscribed cylinder.
Solution:
Let h represent the height of the cylinder, and let r represent the radius of
the cylinder, we have;
r² + h² = 8²
Therefore;
r² = 8² - h² = 64 - h²
r² = 64 - h²
The volume of the cylinder, V = π·r²·h = π·(64 - h²)·h
V(h) = π·(64·h - h³)
At the maximum volume, we have;
[tex]\dfrac{dV(h)}{dh} = \dfrac{d}{dh} \left(\pi \cdot \left(64 \cdot h - h^3 \right) \right) = \pi \cdot \left(64 - 3 \cdot h^2 \right) = 0[/tex]
64 - 3·h² = 0
64 = 3·h²
[tex]h =\sqrt{\dfrac{64}{3} } = \dfrac{8}{\sqrt{3} }[/tex]
[tex]\underline{\mathrm{The \ height \ of \ the \ cylinder, \ h} = \dfrac{8}{\sqrt{3} }}[/tex]
[tex]r^2 = 64 - \dfrac{64}{3} = \dfrac{128}{3}[/tex]
[tex]r =\sqrt{\dfrac{128}{3}} = \dfrac{8 \cdot \sqrt{6} }{3}[/tex]

The tiger's whisker questions and answers.
Answer:
Explanation:
The folktale "The Tiger´s Whisker" originates from Korea, and it is used mostly as a child´s tale. It narrates the story of Yun Ok, whose husband has changed drastically from a loving, and gentle man, to an irrascible one, thanks to the wars. In desperation, Yun Ok, goes to a hermit and asks for a potion. The man tells her that in order to do so, she must bring a whisker from a live tiger. Yun Ok does as she is told, and patiently gains the trust of a tiger, and gets the needed whisker. In the end, she finds out that the lesson the hermit wanted her to learn was that to regain her husband, she needed to apply the same technique she used on the tiger, and not a potion. Given this background, the answers would be thus:
1. A folktale is defined precisely as: A story that is often passed along by word of mouth from one generation to another. This is the correct answer.
2. In this question, the answer is: Her husband has become very distant since he returned from war. This is what is narrated in the story as the reason for Yun Ok´s husband´s estrangement.
3. The correct answer here is: He laughs at Yun Ok´s idea because he thinks she is foolish to believe that solving the problem with her husband could be so simple. Though not directly stated, the hermit does laugh in a way when he says to Yun Ok that healing her husband with a potion is not like taking care of an ear infection. And he makes her feel somewhat foolish for her request. But she insists and he gives in.
4. The answer to this question is: She decides that reconnecting with her husband is worth the risk. This is stated in the story when Yun, although afraid, still continues persistently to go after the tiger, always keeping in mind that all is for the benefit of herself and her husband.
5. The answer here is: She learns that through patience, she can win her husband´s trust and heart like she earned the trust of the tiger. This is the lesson she learns when the hermit burns the whisker and makes her reflect on how she was able to get it from a wild tiger, saying that a man cannot be fiercer, or more difficult, than a tiger.
6. The answer here is: She is patient and demonstrates perseverance by spending six long months, slowly getting the tiger to trust her before she plucks out his whisker. This is exactly what she does in the story. She spends every day of those six months, carefully gaining the tiger´s trust, until he allows her near, and then allows her to take his whisker.

A probe orbiting venus exerts a gravitational force of 2. 58 × 103 n on venus. Venus has a mass of 4. 87 × 1024 kg. The mass of the probe is 655 kilograms. The gravitational constant is 6. 67 × 10-11 n*m2/kg2. To three significant digits, the probe is × 106 m from the center of venus.
Answer:
[tex]\mathrm{9.08 \times 10^6 \:km}[/tex]
Explanation:
To solve for the distance between the probe and the center of Venus, use the formula:
[tex]\mathrm{F = \frac{G\: m1 \:m2}{r^2}}[/tex]
Plugin the values:
G =
[tex]6.67\times10^{-11} \mathrm{\frac{m3}{kg\: s2}}[/tex]
[tex]\mathrm{F} =2.58 \times 10^3\mathrm{N}[/tex]
[tex]\mathrm{m1 = 4.87 \times 10^{24}\:kg}[/tex]
[tex]\mathrm{m2 = 655\: kg}[/tex]
Hence:
[tex]\mathrm{F = \frac{G\: m1 \:m2}{r^2}}[/tex]
[tex]2.58 \times 10^{23} = 6.67 \times 10^{-11} (4.87 \times 10^{24})[/tex]

Using the equations 2 sr(s) + o₂ (g) → 2 sro (s) ∆h° = -1184 kj/mol co₂ (g) → c (s) + o₂ (g) ∆h° = 394 kj/mol determine the molar enthalpy (in kj/mol) for the reaction c(s) + 2 sro(s) → co₂ (g) + 2 sr(s).
Considering the Hess's Law, the enthalpy change for the reaction is 790 kJ/mol.
Hess's Law indicates that the enthalpy change in a chemical reaction is the sum of the ∆H of each stage of the reaction will give us a value equal to the ∆H of the reaction when it occurs in a single stage.
In this case you want to calculate the enthalpy change of:
C(s) + 2 SrO(s) → CO₂ (g) + 2 Sr(s)
You know the following reactions, with their corresponding enthalpies:
Equation 1: 2 Sr (s) + O₂ (g) → 2 SrO (s) ∆H° = -1184 kJ/mol
Equation 2: CO₂ (g) → C (s) + O₂ (g) ∆H° = 394 kJ/mol
First stepIn this case, first, to obtain the enthalpy of the desired chemical reaction you need 1 mole of C (s) on reactant side and it is present in second equation. But since this equation has 1 mole of C (s) on the product side, it is necessary to locate this on the reactant side (invert the reaction). And when an equation is inverted, the sign of ΔH also changes.
Second stepNow, 2 moles of SrO (s) must be a reactant and is present in the first equation. Since this equation has 2 moles of Sr0 (s) on the product side, it is necessary to locate the O on the reactant side (invert the reaction) and the sign of ΔH changes.
SummaryIn summary, you know that two equations with their corresponding enthalpies are:
Equation 1: 2 SrO (s) → 2 Sr (s) + O₂ (g) ∆H° = 1184 kJ/mol
Equation 2: C (s) + O₂ (g) → CO₂ (g) ∆H° = -394 kJ/mol
Adding or canceling the reactants and products as appropriate, and adding the enthalpies algebraically, you obtain:
C(s) + 2 SrO(s) → CO₂ (g) + 2 Sr(s) ΔH= 790 kJ/mol
Finally, the enthalpy change for the reaction is 790 kJ/mol.
