Answer:

ΔG° = 80 Kj/mole

Explanation:

ΔG° = -R·T·ln(Kw)

R = 0.008314 Kj/mol·K

T = 25°C = 298K

Kw = 1 x 10⁻¹⁴

ΔG° = -R·T·ln(Kw) -(0.08314Kj/mol·K)(298K)ln(1 x 10⁻¹⁴)

= -(0.008314)(298)(-32.2)Kj/mole

= 79.78Kj/mole ≈ 80Kj/mole (1 sig.-fig.)

The change in free energy for the autoionization of water at 25°C is -79.9 KJ

Using the formula;

ΔG = -RTlnK

ΔG  = change in free energy = ?

R = gas constant = 8.314 J/K/mol

T = temperature = 298 K

K = equilibrium constant = 1.0 X 10^-14

Substituting into the given formula as;

ΔG = -  (8.314 J/K/mol × 298 K × ln(1.0 X 10^-14))

ΔG = -7.99 × 10^4 J/mol or -79.9 KJ/mol

Answer:

45.3 KPa

Explanation:

From the question given above, the following data were obtained:

Total pressure (Pₜ) = 101.3 KPa

Pressure of Hydrogen (Pₕ) = 56 KPa

Pressure of Oxygen (Pₒ) =?

The pressure of oxygen in the mixture can be obtained as follow:

Pₜ = Pₕ + Pₒ

101.3 = 56 + Pₒ

Collect like terms

101.3 – 56 = Pₒ

Pₒ = 45.3 KPa

Thus, the pressure of oxygen in the mixture is 45.3 KPa

Answer:

I have seen many lightning storms before. However, one of the most surprising ones was when I was at my house. It was around midnight when I awoke from the sound of lightning in the distance. I was also half awake so this could be another reason this was the most surprising, but lightning struck near my area. i could see the light through my curtains and the sound was loud enough to awake everyone in my house, even the deep sleepers. I practically jumped out of bed.

The type of decay that Am-241 undergoes to become Np-237 is alpha decay. The correct option is a.

Alpha decay is a type of decay or transformation in which a nucleus emits an alpha particle and change into different atomic nuclei. The atomic number reduces by 2 and the mass is reduced by 4.

Am-241 is an isotope of the chemical element americium. It is a radioactive element and its radioactive decay period is 432.2 years. It is used in the testing of machinery.

When the nucleus of Am changes or emits a radioactive particle. It converts into Np-237. The process is called alpha decay. The atomic mass is reduced by four, and the 241 converts into 237, which become neptunium.

Thus, the correct option is a. Alpha decay.

Answer:

I dont a picture

Explanation:

but the answer is 24

Answer:

The value 9.8 m/s^2 is the average acceleration of a falling object due to the force of gravity on Earth. The letter g represents this value the formula v=gt. With this constant and formula, the speed of an object is calculated at the time t in seconds after it is dropped.

All objects fall at the same rate of speed due to gravity, regardless of their weight. If a small grain of sand and a bowling ball are dropped at the same time, both hit the floor at the same time. The value of g varies by one's location on the planet, ranging from 9.782 m/s^2 in the Panama Canal Zone to 9.832 m/s^2 at the Noth Pole

Answer:

941 K (668°C)

Explanation:

We have the following data:

Initial pressure : P1 = 1.45 atm

Initial temperature: T1 = 52°C + 273 = 325 K

Final pressure: P2 = 4.2 atm

Final temperature: T2 = ?

The relation between pressure and temperature for a gas at constant volume is given by Gay-Lussac's law:

P1/T1 = P2/T2

That means that the pressure is directly proportional to the absolute temperature (in K). So, we calculate T2 from the equation:

T2 = P2 x T1/P1 = 4.2 atm x (325 K/1.45 atm) = 941 K

Therefore, the final temperature would be 941 K (668°C). This is consistent with the law, that states that if the pressure increase, the temperature will be increased.  

Answer:

8.82 kg es la masa total de leche

Explanation:

Consideraremos que el volumen de cada bolsa de leche es de 900 mL.

Sabiendo que tenemos en total 7 bolsas, el volumen final en litros que tenemos disponible es de:

900 mL . 7 = 6300 mL

Utilizando la densidad podemos calcular la masa de leche que tenemos en el total de las 7 bolsas

Densidad = masa / volumen

Densidad . volumen = masa → 1.4 g/mL . 6300 mL = 8820 g

Convertimos la masa de gramos a kg

8820 g . 1 kg /1000g = 8.82 kg

Answer:

[tex]14.8\ \text{atm}[/tex]

Explanation:

[tex]C_1[/tex] = Initial concentration = 1.46 g/L

[tex]C_2[/tex] = Final concentration = 2.7 g/L

[tex]P_1[/tex] = Initial pressure = 8 atm

[tex]P_2[/tex] = Final pressure

From Henry's law we have the relation

[tex]\dfrac{C_2}{C_1}=\dfrac{P_2}{P_1}\\\Rightarrow P_2=\dfrac{C_2}{C_1}P_1\\\Rightarrow P_2=\dfrac{2.7}{1.46}\times 8\\\Rightarrow P_2=14.8\ \text{atm}[/tex]

The pressure of a sample of the same gas at the required concentration is [tex]14.8\ \text{atm}[/tex].
