Gelneren [198K]

According to Le Chatelier's principle, adding additional reactant to a system will shift the equilibrium to the right, towards the side of the products. ... By Le Chatelier's principle, we can predict that the amount of methanol will increase, thereby decreasing the total change in CO.

The average molecular speed in a sample of Ar gas at a certain temperature is 391 m/s. The average molecular speed in a sample o
adoni [48]

Answer:

550 m/s

Explanation:

The average molecular speed (v) is the speed associated with a group of molecules on average. We can calculate it using the following expression.

v = \sqrt{\frac{3 \times R \times T}{M} }

where,

  • R: ideal gas constant
  • T: absolute temperature
  • M: molar mass of the gas

We can use the info of argon to calculate the temperature for both samples.

T = \frac{v^{2} \times M}{3 \times R} = \frac{(391m/s)^{2} \times 39.95g/mol}{3 \times 8.314J/k.mol} = 2.45 \times 10^{5} K

Now, we can use the same expression to find the average molecular speed in a sample of Ne gas.

v = \sqrt{\frac{3 \times R \times T}{M} } = \sqrt{\frac{3 \times (8.314J/k.mol) \times 2.45 \times  10^{5}K }{20.18g/mol} } = 550 m/s

La lección difícil, cuadro de William-Adolphe Bouguereau.

El aprendizaje es el proceso a través del cual se modifican y adquieren habilidades, destrezas, conocimientos, conductas y valores.1​ Esto como resultado del estudio, la experiencia, la instrucción, el razonamiento y la observación. Este proceso puede ser analizado desde distintas perspectivas, por lo que existen distintas teorías del aprendizaje. Es una de las funciones mentales más importantes en humanos, animales y sistemas artificiales. En él intervienen diversos factores que van desde el medio en el cual se desenvuelve el ser humano, así como los valores y principios que se aprenden en la familia. En esta última se establecen los principios del aprendizaje de todo individuo y se afianza el conocimiento recibido, el cual forma la base para aprendizajes posteriores.

El aprendizaje humano está relacionado con la educación y el desarrollo personal. Debe estar orientado adecuadamente y es óptimo cuando el individuo está motivado. El estudio sobre cómo aprender interesa a las Ciencias de la Educación, la pedagogía, la neuropsicología, la psicología educacional y la antropología, aquella que recoge las peculiaridades propias de cada etapa del desarrollo humano. Concibe sus planteamientos teóricos, metodológicos y didácticos para cada una de ellas. Dentro de ella se enmarcan, por ejemplo la pedagogía y la andragogía, la educación de niños y adultos respectivamente.2​

4.0 mol Na2S reacts with 5.0 mol
Bumek [7]

The number of moles of Na_2SO_4 form from 5.0 moles Na_2S is 5 moles.

<h3>What is a limiting reactant?</h3>

Limiting reactants are those reactants that are completely used up in a chemical reaction.

4.0 mol Na_2S will be completely used since the combining ratio is 1 : 1 : 1.

Na_2S + CuSO_4 ->Na_2SO_4 + CuS

From the chemical equation above, 5.0 moles Na_2S will yield 5 moles of Na_2SO_4.
