A solution of ammonia NH3(aq) is at equilibrium. How would the equilibrium
change if NH4+ were added to the solution?

Answers

Answer 1

Answer: The equilibrium will shift in the direction of [tex]NH_3[/tex]

Explanation:

The chemical equation for the aqueous solution of ammonia follows:

[tex]NH_3+H_2O\rightleftharpoons NH_4^++OH^-[/tex]

According to Le-chtelier's principle:

If there is any change in the variables of the reaction, then the equilibrium will shift in that direction of equilibrium to minimize the effect.

If we add more amount of [tex]NH_4^+[/tex] to the solution, more of the products will be present. But according to Le-chtelier's principle, to minimize this effect, the equilibrium will shift in the backward direction that in the direction of [tex]NH_3[/tex]

Hence, the equilibrium will shift in the direction of [tex]NH_3[/tex]

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

Characteristics such as melting point, boiling point, density, solubility, color, odor, etc.

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].

Read the following reactions. Reaction 1: CaO(s) + CO2(g) → CaCO3(s) Reaction 2: H2O(g) → H2O(l) Which reaction leads to an increase in entropy? Only Reaction 1 Only Reaction 2 Both Reaction 1 and 2 Neither Reaction 1 nor 2

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.

Answer: Neither Reaction 1 nor 2

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]

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

How much energy does a 930 nm wave of light have? (The speed of light in a vacuum is 3.00 x 108 m/s, and Planck's constant is 6.626 x 10-34 J·s.)

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

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.

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 law agrees with the Biblical account of Creation
(more than one answer)

Answers

Answer:

Matter or energy can change from one form to the other

Explanation:

The law of conservation of energy states that energy can neither be created nor destroyed but can only be transformed i.e. changed from one form to another. For example, mechanical energy can be changed to electrical energy.

Likewise, the law of conservation of mass/matter states that matter can not be destroyed or created but can change via physical or chemical means to conserve it. For example, matter can change from liquid state to gaseous state.

From the above two laws, it can be said that "matter or energy can change from one form to the other".
