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​

6. Consider the reaction: CzHo (g) + 02 (8) - 4 CO2(g) + 6H2O (1)
deff fn [24]

Answer:

1120 gm

Explanation:

6. Consider the reaction: CzHo (g) + 02 (8) - 4 CO2(g) + 6H2O (1)

(a) Balance the equation.

(b) How many grams of oxygen are required to react with 10 moles of ethane for a complete

combustion reaction?

FIRST, CORRECT THE EQUATION THEN BALANCE

2C2H6(G) + 7O2------------>  4CO2  + 6H2O

so for 10 moles of ethane, we need

7 X 5 = 35 MOLES O2

=35 MOLES O2

O2 HAS A MOLAR MASS OF 2X16 = 32 gm

35 MOLES OF O2 HAS A MASS OF 35 X 32 =1120 gm
