The solution of sugar at 60.0 degrees celcuis is 290.0 g/ 100 g water. If you add 100.0 g of sugar to 25 g of water at 60.0 degrees celcuis will the sugar dissolve?

Answers

Answer 1

Answer:

you will produce a saturated solution, At 0 degrees Celsius, sugar is claimed to dissolve 180 grams in 100 grams of water. This means that if you dissolve that much sugar in 100 g of water, you'll get a saturated solution.

Explanation:

Answer 2

The correct answer for the given question about Saturated solution is only 72.5 gram will get dissolved and rest which is 27.5 gram will remain undissolved.

How to apply concept of Saturated solution to solve this question?

In question it is given that at 60° C 290 gram of sugar in 100 gram of water produce saturated solution.

So at 60° C  290/100 gram of sugar in 1 gram of water will produce saturated solution.

Hence we can say that  at 60° C  (290/100)×25 gram of sugar in 25 gram of water will produce saturated solution.

means at 60° C 72.5 gram of sugar in 25 gram of water will produce saturated solution.

Now, adding 100 gram of sugar in 25 gram of water.

Since you can only hope to dissolve 72.5 gram at 60°,

Hence the resulting solution will contain undissolved sugar.

So only 72.5 gram will get dissolved and rest which is 27.5 gram will remain undissolved.

Thus, We can conclude that Only 72.5 grams of sugar will dissolve, leaving the remaining  sugar of 27.5 grams undissolved.

How do I solve for a and b using the Van Der Waals equation using only the given values: P= 1 atm, V= 1.310 L, and T= 160 K

Answers

Answer:

[tex]a = \frac{24.79078- 1.7161b}{1.310 - b}[/tex]

[tex]b = 1.310 - \frac{22.5427}{a - 1.7161}[/tex]

Explanation:

Given

[tex]P = 1\ atm[/tex]

[tex]V = 1.310\ L[/tex]

[tex]T =160\ K[/tex]

Required

Solve for a and b

Van Der Waals equation is:

[tex]P = \frac{RT}{V - b} - \frac{a}{V^2}[/tex]

Substitute values for P, V and T, we have:

[tex]1 = \frac{R*160}{1.310 - b} - \frac{a}{1.310^2}[/tex]

R is a constant and the value is:

[tex]R = 0.0821[/tex]

So, the equation becomes:

[tex]1 = \frac{0.0821*160}{1.310 - b} - \frac{a}{1.310^2}[/tex]

Simplify the expression

[tex]1 = \frac{13.136}{1.310 - b} - \frac{a}{1.7161}[/tex] ----- (a)

Solving for (a):

[tex]1 + \frac{13.136}{1.310 - b} = \frac{a}{1.7161}[/tex]

Multiply both sides by 1.7161

[tex]a = [1 + \frac{13.136}{1.310 - b}] * 1.7161[/tex]

Take LCM

[tex]a = [\frac{1.310 - b+13.136}{1.310 - b}] * 1.7161[/tex]

Evaluate like terms

[tex]a = [\frac{14.446- b}{1.310 - b}] * 1.7161[/tex]

Open bracket

[tex]a = [\frac{24.79078- 1.7161b}{1.310 - b}[/tex]

Solving for (b), we have:

[tex]1 + \frac{13.136}{1.310 - b} = \frac{a}{1.7161}[/tex]

Subtract 1 from both sides

[tex]\frac{13.136}{1.310 - b} = \frac{a}{1.7161}-1[/tex]

Take LCM

[tex]\frac{13.136}{1.310 - b} = \frac{a-1.7161}{1.7161}[/tex]

Inverse both sides

[tex]\frac{1.310 - b}{13.136} = \frac{1.7161}{a - 1.7161}[/tex]

Multiply both sides by 13.136

[tex]1.310 - b = 13.136 * \frac{1.7161}{a - 1.7161}[/tex]

[tex]1.310 - b = \frac{22.5427}{a - 1.7161}[/tex]

Collect like terms

[tex]b = 1.310 - \frac{22.5427}{a - 1.7161}[/tex]

A. 4.68 x 10^18 J
B. 2.14 x 10^-19 J
C. 1.85 x 10^-31 J
D. 4.21 x 10^35 J

Answers

Answer:

B. 2.14 x 10^-19 J

Explanation:

The energy of a wave of light can be obtained using the equation:

E = h*c/λ

Where E is the energy in joules,

λ is wavelength = 930nm = 930x10⁻⁹m

h = Planck's constant = 6.626x10⁻³⁴Js

c = Speed of light = 3.00x10⁸m/s

Replacing:

E = 6.626x10⁻³⁴Js*3.00x10⁸m/s/930x10⁻⁹m

E = 2.14x10⁻¹⁹J

Right option is:

B. 2.14 x 10^-19 J

Find the boiling point of a solution of 2.00 m solution of sodium chloride, NaCl, in water (kb= 0.512°C, bp= 100.0°C)

Answers

Answer: Boiling point of the given solution is [tex]102.048^{o}C[/tex].

Explanation:

Given: Molality = 2.00 m

[tex]k_{b} = 0.512^{o}C[/tex]

Now, equation for dissociation of water is as follows.

[tex]H_{2}O \rightarrow H^{+} + OH^{-}[/tex]

As it is giving 2 ions upon dissociation. So, the value of i = 2.

Formula used to calculate change in temperature is as follows.

[tex]\Delta T = i \times k_{b} \times m[/tex]

where,

i = Van't Hoff factor

[tex]k_{b}[/tex] = molal boiling point elevation constant

m = molality

Substitute the values into above formula as follows.

[tex]\Delta T = i \times k_{b} \times m\\= 2 \times 0.512^{o}C \times 2.00 m\\= 2.048^{o}C[/tex]

As the boiling point of water is [tex]100^{o}C[/tex]. Hence, the boiling point of solution will be as follows.

[tex]\Delta T^{'}_{b} = 100^{o}C + 2.048^{o}C\\= 102.048^{o}C[/tex]

Thus, we can conclude that boiling point of the given solution is [tex]102.048^{o}C[/tex].

The two types of downbursts are macrobursts and microbursts. A macroburst affects an area that's greater than 2.5 miles across. A microburst affects an area that's less than 2.5 miles across.

A funnel cloud forms as a spinning column of air that descends from a thundercloud. However, a funnel cloud doesn't become a tornado until it actually touches the ground. Once it touches the ground, where it begins to pick up dust and debris, it becomes a tornado.

Tropical cyclones, such as hurricanes, are fueled by warm ocean waters. Once they make landfall, they lose this fuel source and begin to lose strength.

The heat index and the wind chill index are similar because both consider other factors that affect how air temperature feels. The heat index considers relative humidity in relation to air temperature. Higher humidity makes air temperatures feel hotter. The wind chill index considers wind speed in relation to air temperature. Higher wind speeds make air temperatures feel colder.

Heat waves—Heat waves can be very dangerous when accompanied by high humidity. The human body depends on evaporation of sweat to cool itself down on hot days. When humidity levels are high, the rate of evaporation slows down. Consequently, it becomes harder for the body to cool itself and much easier for the body to overheat.

Teniendo en cuenta la siguiente reacción quimica: Mn (NO3)2 + NaBiO; + HNO, HMnO₂+ Bi (NO3)3 + NaNO3 + H₂O ¿Cuánto Bi (NO₂), se obtiene a partir de 650 g de Mn (NO₂)2 y 700 g de NaBiO, si la eficiencia del proceso es de un 80%?

Answers

Answer:

La masa de Bi (NO₃) ₃ producida es de aproximadamente 2.117,09 gramos

Explanation:

La ecuación química de la reacción se presenta como sigue;

2Mn (NO₃) ₂ + 5NaBiO₃ + 14HNO₃ → 2HMnO₄ + 5Bi (NO₃) ₃ + 5NaNO₃ + 7H₂O

La masa dada de Mn (NO₃) ₂ = 650 g

La masa de NaBiO₃ = 750 g

El número de moles de Mn (NO₃) ₂ = 650 g / (178.95 g / mol) ≈ 3.63 moles

El número de moles de NaBiO₃ = 750 g / (279.968 g / mol) ≈ 2.68 moles

Por lo tanto, el NaBiO₃, es el reactivo limitante, y el rendimiento teórico de Bi (NO₃) ₃ ≈ 5/2 × 2.68 = 6.7 moles

Dado que la eficiencia del proceso es del 80%, el rendimiento real de Bi (NO₃) ₃ = 0,8 × 6,7 moles = 5,36 moles de Bi (NO₃) ₃

La masa molar de Bi (NO₃) ₃ ≈ 394,98 g / mol

La masa de Bi (NO₃) ₃ = 394,98 g / mol × 5,36 moles ≈ 2,117,09 g

La masa de Bi (NO₃) ₃ produjo ≈ 2,117.09 g

The expression below was formed by combining different gas laws. V is proportional to StartFraction n T over P EndFraction. Which law was used to determine the relationship between the volume and the number of moles in this equation?

Answers

Answer:

The Ideal gas law

Explanation:

From the given question, we have:

V [tex]\alpha[/tex] [tex]\frac{nT}{P}[/tex]

where each variable has its usual meaning.

Thus,

V = [tex]\frac{nRT}{P}[/tex]

where R is the ideal gas constant

cross multiply to have;

PV = nRT

This implies that the volume of the gas is directly proportional to the number of moles of the gas.

Therefore, the law can be used to determine the relationship between the volume and number of moles is the ideal gas law.

The frequency of an X ray is 6.5 x 1018 Hz. What is the X ray’s wavelength? .

Answers

Answer:

The X ray’s wavelength is 4.61*10⁻¹¹ m

Explanation:

Wavelength is the minimum distance between two successive points on the wave that are in the same state of vibration. It is expressed in units of length (m).

Frequency is the number of vibrations that occur in a unit of time. Its unit is s⁻¹ or hertz (Hz).

The propagation speed is the speed with which the wave propagates in the medium, that is, it is the magnitude that measures the speed at which the wave's disturbance propagates along its displacement. Relate the wavelength (λ) and the frequency (f) inversely proportional using the following equation:

v = f * λ.

In this case:

The frecuency f= 6.5*10¹⁸ Hz The speed v=c= 3*10⁸ [tex]\frac{m}{s}[/tex]

Replacing:

3*10⁸ [tex]\frac{m}{s}[/tex]= 6.5*10¹⁸ Hz* λ

Solving:

[tex]wavelength= \frac{3*10^{8} \frac{m}{s} }{6.5*10^{18} Hz}[/tex]

λ= 4.61*10⁻¹¹ m

The X ray’s wavelength is 4.61*10⁻¹¹ m

Answers

Answer: In the given reactions neither reaction 1 nor 2 reaction leads to an increase in entropy.

Explanation:

The degree of randomness present in the molecules of a substance is called entropy.

In gases, molecules are held by weak forces due to which they move apart from each other. Hence, they have high entropy.

In liquids, molecules are a little close to each other so they have less entropy than gases.

In solids, molecules are tightly held together so they have least or negligible entropy.

As reaction 1 is [tex]CaO(s) + CO_{2}(g) \rightarrow CaCO_{3}(s)[/tex] and it shows that product is in solid state. Therefore, entropy is decreasing.

As reaction 2 is [tex]H_{2}O(g) \rightarrow H_{2}O(l)[/tex] and it shows that gas is converted into liquid. Therefore, entropy is also decreasing here.

Thus, we can conclude that in the given reactions neither reaction 1 nor 2 reaction leads to an increase in entropy.
