Copper is formed when aluminum reacts with copper (II) sulfate in a single-replacement reaction. How many moles of copper can be
serg [7]

Answer:

The answer to your question is the limiting reactant is CuSO₄ and 0.975 moles of Cu were obtained

Explanation:

moles of Copper = ?

mass of Aluminum = 29 g

mass of CuSO₄ = 156 g

Limiting reactant = ?

Balanced Chemical reaction

                  3 CuSO₄   +  2 Al   ⇒   3 Cu   +  Al₂(SO₄)₃

Calculate the moles of reactants

CuSO₄ = 64 + 32 + (16 x 4) = 160g

Al = 27 g

                160 g of CuSO₄  ----------------- 1 mol

                156 g                   -----------------  x

                      x = (156 x 1) / 160

                      x = 0.975 moles

               27 g of Al -------------------------- 1 mol

               29 g of Al -------------------------- x

                x = (29 x 1)/27

                x = 1.07 moles

Calculate proportions to find the limiting reactant

Theoretical     3 moles CuSO₄/2 moles Al = 1.5 moles

Experimental  0.975 moles CuSO₄/1.07 moles = 0.91

The experimental proportion was lower than the theoretical proportion that means that the limiting reactant is CuSO₄.      

                    3 moles of CuSO₄ ------------------ 3 moles of Cu

                 0.975 moles of CuSO₄ ---------------  x

                         x = (0.975 x 3)/3

                        x = 0.975 moles of Cu were obtained.

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​

A compound was found to have 85.7% carbon and 14.3% hydrogen. Its molecular mass is 84. What is its empirical formula? What is i
Ludmilka [50]

Answer:

The molecular formula is C₆H₁₂

The empirical formula is CH₂

Explanation:

Percent by mass, means that in 100 g of compound we have:

85.7 g of C

14.3 g of H

Let's make a rule of three with the molar mass to determine the amounts of the elements:

In 100 g of compound we have 85.7 g of C

In 84 g of compound we would have (84 . 85.7) / 100 = 72 g of C

In 100 g of compound we have 14.3 g of H

Then, in 84 g of compound we would have (84 . 14.3) / 100 = 12 g of H

Now let's determine the moles of each element

72 g of C / 12 g/mol = 6 mol of C

12 g of H / 1 g/mol = 12 mol of H

Then, the molecular formula is C₆H₁₂

The empirical formula is CH₂
