A 25.0 L gas cylinder at 32.0 is filled with 2.33 moles of carbon dioxide and 4.66 moles of nitrogen. Calculate the total pressu
Phantasy [73]

Answer:

P= 7.01 atm

P(CO₂)= 2.34 atm

Explanation:

Step 1: Convert the temperature to Kelvin

We will use the following expression.

K = °C + 273.15

K = 32.0°C + 273.15 = 305.2 K

Step 2: Calculate the total number of moles of the mixture

We will use the following expression.

n = nCO₂ + nN₂ = 2.33 mol + 4.66 mol = 6.99 mol

Step 3: Calculate the total pressure of the mixture

We will use the ideal gas equation.

P × V = n × R × T

P = n × R × T / V

P = 6.99 mol × 0.0821 atm.L/mol.K × 305.2 K / 25.0 L

P= 7.01 atm

Step 4: Calculate the partial pressure of carbon dioxide

We will use the ideal gas equation.

P(CO₂) × V = nCO₂ × R × T

P(CO₂) = nCO₂ × R × T / V

P(CO₂) = 2.33 mol × 0.0821 atm.L/mol.K × 305.2 K / 25.0 L

P(CO₂)= 2.34 atm

Que relación tiene el metabolismo celular con el mantenimiento de los seres vivos
Dmitry [639]
El metabolismo es un proceso por el cual los seres vivos ganan masa y energía que ofrece el medio en el que viven y sirve para el mantenimiento, crecimiento y reproducción de estos.

Si tomamos en cuenta la clasificación de los seres vivos tenemos:

- Autótrofos: Crean su propio alimento por medio del sol o la tierra y no de otros seres vivos (plantas, vegetales y algas).

- Heterótrofos: Generan su propio alimento y dependen de los autótrofos o de otros heterótrofos para su alimentación (animales y algunas bacterias).

El metabolismo se divide en dos procesos conjugados, el catabolismo y el anabolismo. Estos procesos dependen el uno del otro.

Las reacciones catabólicas liberan energía, mientras que las reacciones anabólicas, utilizan esa energía liberada para recomponer enlaces químicos y construir componentes de las células como las proteínas y los ácidos nucleicos..

De esta manera se relacionan ambos

How many protons are in an element with an atomic number of 8 and mass number of 18
Lemur [1.5K]

Answer:8

Explanation:

Atomic number = 8

Mass number = 18

The number of protons and the number of electrons is equal to the atomic number.

The number of neutrons in the nucleus is given by the difference in mass number and atomic number.

So, number of protons are 8

number of electrons = 8

number of neutrons = 18 - 8 = 10
