what will happen when the rates of evaporation and condensation are equal​

Answer:

The pressure of the gas at 323 degrees Celsius is 2 atm.

Explanation:

Gay-Lussac's law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions with the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.

In short, when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases.

Gay-Lussac's law can be expressed mathematically as follows:

[tex]\frac{P}{T} =k[/tex]

Where P = pressure, T = temperature, K = Constant

Having two different states, an initial state 1 and a final state 2, it is satisfied:

[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]

In this case:

Replacing:

[tex]\frac{1 atm}{298 K} =\frac{P2}{596 K}[/tex]

Solving:

[tex]P2=\frac{1 atm}{298 K}*596 K[/tex]

P2= 2 atm

The pressure of the gas at 323 degrees Celsius is 2 atm.

Answer:

98 g/mol

Explanation:

La masa molar de un compuesto es la cantidad de materia (medida como masa) que hay en 1 mol de dicho compuesto. Por lo tanto, puede calcularse como sigue:

masa molar = masa/número moles

Tenemos los siguientes datos del compuesto Y:

masa Y = 196 g

número de moles de Y = 2 mol

Entonces, podemos calcular la masa molar de Y de la siguiente manera:

masa molar Y = (masa Y)/(número de moles de Y) = 196 g/2 mol = 98 g/mol

Answer:

41.8 g of water.

Explanation:

To solve this, we introduce the concept of mol.

1 mol of anything contains 6.02×10²³ particles.

In this case, we talk about molecules of water.

Molecular weigh is 18 g/mol which indicates that 1 mol of water weighs 18 g.

So let's do the conversion

(18 g of water / 6.02×10²³ 1 mol of molecules) . 1.4×10²⁴ molecules = 41.8 g

Answer: The pressure is 2.14 atm if the gas was heated to 373 K and the volume decreased to 1.90 L.

Explanation:

Given: [tex]V_{1} = 2.50 L[/tex],      [tex]P_{1} = 1.34 atm[/tex],       [tex]T_{1} = 308 K[/tex]

[tex]P_{2} = ?[/tex] ,            [tex]V_{2} = 1.90 L[/tex],          [tex]T_{1} = 373 K[/tex]

Formula used to calculate the final pressure is as follows.

[tex]\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}[/tex]

Substitute the values into above formula as follows.

[tex]\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}\\\frac{1.34 atm \times 2.50 L}{308 K} = \frac{P_{2} \times 1.90 L}{373 K}\\P_{2} = \frac{1.34 atm \times 2.50 L \times 373}{308 K \times 1.90 L}\\= 2.14 atm[/tex]

Thus, we can conclude that the pressure is 2.14 atm if the gas was heated to 373 K and the volume decreased to 1.90 L.

What happen if your Adrenal Glands become overprotective of underproductive?

Answer: if your adrenals becomes overproductive it will lead to a health issue known as CUSHING'S SYNDROME while when they become underproductive it will lead to a health condition known as ADDISON'S DISEASE.

Explanation:

The adrenal glands are divided into two embryologically and functionally distinct parts: the adrenal cortex and adrenal medulla.

The adrenal cortex is part of the hypothalamic - pituitary - adrenal endocrine system. Morphologically, the adult adrenal cortex consists of three layers which include:

--> The outer thin layer: this is also called zona glomerulosa. It secrets only aldosterone.

--> The inner two layers: these comprises of the zona fasciculata and zona reticularis. They both form a functional unit and secrete most of the adrenocortical hormones.

The adrenal medulla is the inner part of the adrenal gland which secrets the adrenaline and noradrenaline hormones.thry take part in sympathetic nervous system.

When the adrenal glands become a OVERPRODUCTIVE, the adrenal cortex is highly affected. This may occur due to hyperstimulation of the adrenal gland by adrenocorticotrophic hormone,either from the pituitary gland or from an ectopic source or due to largely autonomous secretion by an adrenal tumor such as an adenoma or carcinoma. The increased endogenous cortisol production leads to a disorder known as CUSHING'S SYNDROME. The clinical and metabolic features include obesity, hyperglycaemia and hypertension.

Also when the adrenal glands become UNDERPRODUCTIVE, a health condition known as ADDISON'S DISEASE may occur. This is cause any the bilateral destruction of all zones of the adrenal cortex, usually as the result of an autoimmune process or mycotic infections. The resulting decrease in cortisol production may lead to clinical features such as hypotension, hypoglycemia, nausea and vomiting.

Answer: There is 0.8 liters (L) of water required to be added to prepare 4800mL of 0.5M NaCl from a 3M NaCl stock solution.

Explanation:

Given: [tex]M_{1}[/tex] = 0.5 M        

[tex]V_{1}[/tex] = 4800 mL

Convert mL into L as follows.

[tex]1 mL = 0.001 L\\4800 mL = 4800 mL \times \frac{0.001 L}{1 mL}\\= 4.8 L[/tex]

[tex]M_{2}[/tex] = 3 M

Formula used to calculate the volume of water required as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}[/tex]

Substitute the values into above formula.

[tex]M_{1}V_{1} = M_{2}V_{2}\\0.5 M \times 4.8 L = 3 M \times V_{2}\\V_{2} = \frac{0.5 M \times 4.8 L}{3 M}\\= 0.8 L[/tex]

Thus, we can conclude that 0.8 liters (L) of water need to be added to prepare 4800mL of 0.5M NaCl from a 3M NaCl stock solution.

Answer:

Answer:

Explanation:

The mass of the sun is about 1.98 x 10^30 kilograms. The mass of the earth is 5.97x 10^24 kilograms.

1.98 x 10^30 / 5.97x 10^24 = 331658 times greater

Answer:

Explanation:

The mass of the sun / the mass of the earth

= 1.98 x 10^30 / 5.97x 10^24

= 3.32 x 10^5 times greater

Answer:

Avogadro's Law; 15.1L

Explanation:

Boyle's Law- Pressure and volume are inversely related, so an increase in pressure= decrease in volume. We see this in the equation P1V1=P2V2.

Charle's Law- Gas expands/increases in volume when temperature increases, so they are proportional. We see this in the formula [tex]\frac{V1}{T1} = \frac{V2}{T2}[/tex].

Guy-Lussac's Law-  As temperature increases, pressure increases, so they are proportional. We see this in the formula [tex]\frac{P1}{T1} = \frac{P2}{T2}[/tex].

Avogadro's Law- There are equal amount of volume have an equal amount of moles, so they are proportional. We see this in the formula [tex]\frac{V1}{n1} = \frac{V2}{n2}[/tex].

Plugging in the values based on Avogadro's Law, we'll have:

[tex]\frac{36.5}{2.9} = \frac{V2}{1.2}[/tex]

12.6 = [tex]\frac{V2}{1.2}[/tex]

12.6 x 1.2 = V2

15.1L =V2

Answer:

2260 J

Explanation:

For water at its boiling point of 100 ºC, the heat of vaporization is 2260 J g-1. This means that to convert 1 g of water at 100 ºC to 1 g of steam at 100 ºC, 2260 J of heat must be absorbed by the water.

Answer:

option d) is the correct answer

Answer:

Yes

Explanation:

The expansion of the universe is the increase in distance between any two given gravitationally unbound parts of the observable universe with time. It is an intrinsic expansion whereby the scale of space itself changes. The universe does not expand "into" anything and does not require space to exist "outside" it.

Answer:

The answer is "As [tex]Q=336[/tex], at high-temperature [tex]\Delta G_{rxn}>0[/tex] and When[tex]K>1,[/tex][tex]\Delta G^{\circ}_{rxn}>0[/tex]."

Explanation:

The equation for the reaction is:

[tex]A(g) \leftrightharpoons B(g)[/tex]  

[tex]K=5.8\\\\Q=336[/tex]

At equilibrium,

[tex]\Delta G^{\circ}_{rxn}>0[/tex][tex]=-RT \ln \ K[/tex]

When k=5.8(>1), the value of [tex]\ln k[/tex] would be positive

So, [tex]\Delta G^{\circ}_{rxn}[/tex] is negative (< 0)

So if K > l, [tex]\Delta G^{\circ}_{rxn}<0[/tex]

If the reaction is not in equilibrium so the equation is :

[tex]\Delta G_{rxn}>0[/tex]=[tex]\Delta G^{\circ}_{rxn}[/tex][tex]+RT \ln Q[/tex]

Substituting the expression:

[tex]\Delta G_{rxn}>0[/tex][tex]= (-RT \ln K) + RT \ln Q[/tex]

                 [tex]= RT(\ln Q- \ln K)\\= RT(\ln (336)-\ln (5.8))\\= RT(4.06)[/tex]

It is the positive value for all temperatures.

So, As Q = 336, at the high temperature [tex]\Delta G_{rxn}>0[/tex].

Answer:

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

Since we're finding the new pressure

[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]

We have

[tex]P_2 = \frac{6.4 \times 0.87}{20.5} = \frac{5.568}{20.5} \\ = 0.2716.... \\ \\ = 0.27 \: \: \: atm[/tex]

But

1 atm = 14.7 psi

Then 0.27 atm =

[tex] \frac{14.7 \times 0.27}{1} = 3.969 \\ [/tex]

We have the final answer as
