Answer:

Los alcoholes de cadena larga tienen altos puntos de ebullición. Además, cuando tienen ramificación, el punto de ebullición disminuye

Explanation:

El punto de ebullición de un alcohol se ve afectado, las interacciones dipolo-dipolo, las fuerzas de dispersión de van der Waals y los enlaces de hidrógeno.

Las fuerzas de las interacciones dipolo-dipolo y los enlaces de hidrógeno son más o menos las mismas en la serie de alcohol en serie, sin embargo, a medida que aumenta la longitud del alcohol, las fuerzas de dispersión de van der Waals aumentan debido al aumento de la atracción dipolo-dipolo.

Sin embargo, a medida que el alcohol se vuelve más ramificado, el área de la superficie aumenta, lo que disminuye las fuerzas de van der Waals, de modo que se requiere menos fuerza para separar las moléculas y hervir una muestra del alcohol.

Por tanto, los alcoholes de cadena larga tienen puntos de ebullición elevados. Además, cuando tienen ramificación, el punto de ebullición disminuye.

Answer: 0.0054 s

Explanation: There is an inverse relation between the frequency  and the period  of a wave (a sound wave in this case):

T=1/F

Where f = 1.85 (10)² H z

Hence : T = 1/1.85 (10)² H z T =0.0054s

Explanation:

The person who looks at the different area managers in a large corporation such as in HR, Business Information and Operations is known as a general manager.

An organizational structure can be described as the process which involves dividing an organization into several functional units. A functional organizational structure is a kind of structure used to organize staff by categorizing them into several departments based on their roles or functions, skill sets, and knowledge.

These departments are vertically structured and may include IT, sales, finance and marketing, research, customer service, etc. The various departments are headed by functional managers who have the responsibility of managing, overseeing, and reporting to the executive management.

A manager is an individual who has the responsibility of providing guidance,  supervision, support, and administrative control, as well as acting as a role model to the employees working in an organization.

Generally, managers are involved in taking up leadership roles and are expected to build strong relationships with their subordinates by providing a fair ground for effective communication and sharing of resources.

Have a great day!!! :)

Answer:nope

Explanation:

Just no

Answer:

To have the electronic configuration equal to 1s²2s²2p⁶3s²3p⁶4s²3d⁷, the chemical element must have an electrical charge equal to 27, that is, it must have 27 electrons, such as Cobalt (Co), for example.

Explanation:

The electronic configuration shown in the question above is known as the Linus Pauling distribution and represents the energy sub-levels that an electrically charged atom can have in relation to the amount of electrons it has.

The layers sub-levels are presented in the following order 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹º 4p⁶ 5s² 4d¹º 5p⁶ 6s² 4f14 5d¹º 6p⁶ 7s² 5f14 6d¹º 7p⁶. Where the small numbers represent the number of electrons in each sub-level and the large numbers represent the layers of electronic distribution.

Accordingly, we can see that an atom that has the configuration 1s²2s²2p⁶3s²3p⁶4s²3d⁷ has 27 electrons, like Cobalt.

Answer:

Energy is converted in a hydroelectric plant as follows;

The kinetic energy of water turns turbines; the mechanical energy of the turbines turns the generator, which produces electrical energy

Explanation:

The water in an hydroelectric plant is given potential energy by building an artificial dam to raise the height of the water above the turbine

The high potential energy of the water is converted to kinetic energy which provides the power that turns the turbine transforming the kinetic energy of the water into rotational kinetic energy of the turbine by conservation of mechanical energy;

The shaft connected between the turbine and the generator, turns the generator by the mechanical energy of the turbine and as the generator turns in a magnetic field, electricity is produced by magnetic induction according to Faraday's law.

Answer:

0.087 g/cm^3

Explanation:

Density is Mass : Volume.

Volume = 12 x 8 x 9 = 864 cm^3

Mass = 75 g

Density = 75g/864 cm^3 = 0.087 g/cm^3

The density of a 75 g block of wood measuring 12 cm x 8 cm x 9 cm is 8.6 x 10⁻⁵ Kg/cm³.

Density is defined as the mass per unit volume of the body. Mathematically-

ρ = M/V

Given is a 75 g block of wood measuring 12 cm x 8 cm x 9 cm.

We can write -

Mass = [m] = 75 g = 75/1000 = 0.075 Kg

Volume = [V] = L x B x H = 12 x 8 x 9 = 864 cm³

Therefore, the density of the object will be -

ρ = M/V

ρ = 0.075/864

ρ = 8.6 x 10⁻⁵ Kg/cm³

Therefore, the density of a 75 g block of wood measuring 12 cm x 8 cm x 9 cm is 8.6 x 10⁻⁵ Kg/cm³.

Answer:

0.35 M

Explanation:

HCl + NaOH --> NaCl + H2O

Since the ratio HCl : NaOH is 1:1, you can apply the formula:

Ma x Va = Mb x Vb

Vb = 14 ml (based on the table)

Va = 10 ml

Mb = 0.25 M

Ma = (Mb x Vb)/Ma = (14 x 0.25)/ 10 = 0.35 M

Answer:

27.03 grams

Explanation:

moles (n) = mass(m)/Molar mass(M)

moles = 1.59

mass = ?

N = 14, H = 1

M(NH3) = 14 + 3(1) = 17

Substitute the values into the equation:

nM = m

∴ m = 1.59 × 17 = 27.03
