Answer:

D. 4:3

Explanation:

The mole ratio is simply the coefficients in a balanced chemical reaction and their relation to each other. For example, the mole ratio between Al and [tex]Al_{2}O_{3}[/tex] is 2:1, and the ratio between [tex]O_{2}[/tex] and [tex]Al_{2}O_{3}[/tex] is 3:2.

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:

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

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:

2.04 g/cm3

Explanation:

Density = mass ÷ volume

=2.04 g/cm3

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].

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:

Option D.

Explanation:

Percentage yield = Actual yield / Theoretical yield * 100%

Actual yield = 11.0 grams

Theoretical yield = 12.3 grams

Percentage yield = 11.0 / 12.3  *  100

Percentage yield = 89.43%

Aerobic cellular respiration requires an adequate supply of oxygen. In the presence of oxygen, the cell completely oxidised the glucose molecule to form ATP.

In cellular respiration, the cell takes glucose and breaks it down to form energy. Cellular respiration is of two types: aerobic respiration and anaerobic respiration.

In aerobic respiration, the cell requires oxygen. Due to the presence of oxygen, the complete oxidation of glucose takes place. Glucose is converted into pyruvic acid and then enters the Krebs cycle and the electron transport chain to make ATP.

In the aerobic cellular respiration process, the maximum amount of ATP is derived. In anaerobic respiration, the cell performs respiration without the presence of oxygen. An example is glycolysis.

In this glycolysis process, the complete oxidation of glucose does not take place. In the absence of oxygen from pyruvate, lactic acid and ethanol are produced. This is called fermentation.

Hence, for aerobic cellular respiration, oxygen is required.
