Answer:

El volumen que ocupará la misma masa de aire es 839.49 mL.

Explanation:

Las condiciones normales de presión y temperatura (abreviado CNPT) o presión y temperatura normales (abreviado PTN o TPN), son términos que implican que la temperatura referenciada es de 0ºC (273,15 K) y la presión de 1 atm (definida como 101.325 Pa).

La ley de Boyle dice que “El volumen ocupado por una determinada masa gaseosa a temperatura constante, es inversamente proporcional a la presión”  y se matemáticamente como

Presión*Volumen=constante

o P*V=k

La ley de Charles es una ley que dice que cuando la cantidad de gas y de presión se mantienen constantes, el cociente que existe entre el volumen y la temperatura siempre tendrán el mismo valor:  

\(\frac{V}{T} =k\)

La ley de Gay-Lussac​ establece que la presión de un volumen fijo de un gas, es directamente proporcional a su temperatura. Se expresa matemáticamente como:

\(\frac{P}{T} =k\)

Combinando estas tres leyes se obtiene:

\(\frac{P*V}{T} =k\)

Siendo un estado inicial 1 y un estado final 2, la expresión anterior queda determinada como:

\(\frac{P1*V1}{T1} =\frac{P2*V2}{T2}\)

En este caso:

Reemplazando:

\(\frac{101325 Pa*773 mL}{273,15 K} =\frac{93300 Pa*V2}{273.15 K}\)

y resolviendo obtenes:

\(V2=\frac{273.15 K}{93300 Pa} *\frac{101325 Pa*773 mL}{273,15 K}\)

V2= 839,49 mL

El volumen que ocupará la misma masa de aire es 839.49 mL.

Answer: \(K_2SO_4\rightarrow 2K^++SO_4^{2-}\)

concentration of \(K^+\)  = 0.50 M

concentration of  \(SO_4^{2-}\) = 0.25 M

Explanation:

The dissociation equation of \(K_2SO_4\) is:

\(K_2SO_4\rightarrow 2K^++SO_4^{2-}\)

According to stoichiometry:

1 mole of \(K_2SO_4\) gives 2 moles of \(K^+\)

Thus 0.25 moles of \(K_2SO_4\) gives =\(\frac{2}{1}\times 0.25=0.50\) moles of \(K^+\)

Similarly,

1 mole of \(K_2SO_4\) gives = 1 mole of \(SO_4^{2-}\)

Thus 0.25 moles of \(K_2SO_4\) gives =\(\frac{1}{1}\times 0.25=0.25\) moles of \(SO_4^{2-}\)

Thus the concentration of \(K^+\) and \(SO_4^{2-}\) are 0.50 M and 0.25 M respectively.

Let's see

Explanation:

The equilibrium of a weak base as NX3 is:

NX3(aq) + H2O(l) ⇄ HNX3⁺(aq) + OH-(aq)

Where the equilibrium constant, Kb, is:

Kb = 2.5x10⁻⁶ = [HNX3⁺] [OH-] / [NX3]

As both HNX3⁺ and OH- ions comes from the same equilibrium, their concentrations are the same, that is:

[HNX3⁺] = X

[OH-] = X

And: [NX3] = 0.175M:

2.5x10⁻⁶ = [X] [X] / [0.175M]

4.375x10⁻⁷ = X²

X = 6.61x10⁻⁴M = [OH-]

As pOH = -log [OH-]

The yield stress is known as the stress at which the material starts to deform plastically or permanently. The Hall-Petch equation is an empirical relationship that connects the yield stress with grain size in metals.

The Hall-Petch equation can be written as: \(σy = σ0 + kY / d1/2\). whereσy: the yield stressσ0: the friction stress of the metal K: a constant that is related to the strength of the materialY: the average grain size of the metal in micrometers (μm)In this case, the yield stresses σY were measured for steel specimens of different grain sizes.

The values are shown below :Grain size (μm) Yield stress (MPa)10 31020 36030 41040 44050 45060 46070 47080 48090 490100 500

(a) Determine the values of σ0 and kY in the Hall-Petch equation.σy = σ0 + kY / d1/2. Rearranging the equation, we get:kY = (σy - σ0) * d1/2.

Taking values from the table, we can find kY for each grain size. The results are given below: Grain size (μm) Yield stress (MPa) kY (MPa μm-1/2)10 310 32.520 360 24.530 410 18.740 440 15.650 450 13.260 460 11.770 470 10.280 480 9.490 490 8.7100 500 8.1

Now we can use the average kY to find \(σ0.σ0 = σy - kY / d1/2\). Taking the average values of kY for the grain sizes, we get: \(kY average = 15.84 MPa μm-1/2\). Now we can use the equation above to find σ0:σ0 = σy - kY / d1/2σ0 = 310 - 15.84 / 10^(0.5)σ0 = 303.23 MPa.

Therefore, the values of σ0 and kY are \(σ0 = 303.23 MPa\) and \(kY = 15.84 MPa μm-1/2\).

(b) Determine the yield stress for a grain size of d = 30μm.σy = σ0 + kY / d1/2σy = 303.23 + 15.84 / 30^(0.5)σy = 410.22 MPa. \(d = 30μm.σy = σ0 + kY / d1/2σy = 303.23 + 15.84 / 30^(0.5)σy = 410.22 MPa\). Therefore, the yield stress for a grain size of \(d = 30μm is 410.22 MPa.\).

When a bunch of salt is added and stirred into the ice, the lowest temperature that can be attained will be at -21 °C

.Why?

Adding salt to ice lowers its freezing point. In other words, the salt makes the ice melt at a temperature lower than 0 °C. Salt dissolves in the liquid water in ice, which lowers the temperature of the mixture. Therefore, the lowest temperature is at -21 °C. In addition, the temperature stays at this level because the process of melting the ice takes energy from the saltwater mixture, which keeps the temperature from rising.What happens to the amount of liquid present if you keep stirring and adding salt?The amount of liquid present will increase if you keep stirring and adding salt. When salt is added to ice, it lowers the freezing point of water. As a result, the ice begins to melt, producing liquid water. Therefore, by adding salt to the ice, the amount of liquid present increases. This effect is the opposite of the one that happens when water is cooled and frozen. The water molecules bond and form ice, reducing the amount of liquid present.  How can we understand this phenomenon in terms of thermal and bond energy systems?This phenomenon can be explained by the Energy-Interaction Model. When ice is mixed with salt, thermal energy moves from the surroundings into the system, which reduces the temperature of the mixture. As the ice melts, the energy required to break the bonds between water molecules is taken from the surroundings. The bonds between the water molecules are weakened when salt is added, which requires less energy to break. Thus, the addition of salt allows more energy to be taken from the surroundings and the temperature to drop further.Explanation of changes observed in this physical system (decrease in temperature and change of phase) in terms of the Energy-Interaction Model:When the salt is added to the ice, the thermal energy from the surroundings moves into the system. This reduces the temperature of the mixture. As the ice melts, the energy required to break the bonds between water molecules is taken from the surroundings. The bonds between the water molecules are weakened when salt is added, which requires less energy to break. Thus, the addition of salt allows more energy to be taken from the surroundings and the temperature to drop further. The melting process results in the formation of a saltwater solution, which is a change in the phase of matter. The salt dissolves in the liquid water, which decreases the freezing point and allows the liquid water to exist at a temperature below 0 °C.

The statements that correctly explains the use of physical properties of a substance to separate mixtures are

Statement 1: When substances are mixed together, they retain their physical properties.

Statement 3: When substances are mixed together, the mixture assumes the physical properties of each individual substance.

Mixtures are compounds that are made up of two or more chemical compounds which are not linked to each other chemically. They can be easily separated as there are no chemical reaction between each other.

Mixtures are compounds that retain their respective physical properties even though they were mixed together as there are no reaction between the two. Thus, these physical properties can be used to separate mixtures. Example: Oil in water. They have different densities. Thus, oil will float on water. We can exploit this physical property and separate them using separating funnel.

Mixtures contain different substances with different properties and chemists cannot separate one item from the mixture by forcing it to undergo a chemical change as there is no chemical reaction.
