Electronics Configuration (2024)

Answer: The pressure is 2.14 atm if the gas was heated to 373 K and the volume decreased to 1.90 L.

Explanation:

Given: [tex]V_{1} = 2.50 L[/tex], [tex]P_{1} = 1.34 atm[/tex], [tex]T_{1} = 308 K[/tex]

[tex]P_{2} = ?[/tex] , [tex]V_{2} = 1.90 L[/tex], [tex]T_{1} = 373 K[/tex]

Formula used to calculate the final pressure is as follows.

[tex]\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}[/tex]

Substitute the values into above formula as follows.

[tex]\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}\\\frac{1.34 atm \times 2.50 L}{308 K} = \frac{P_{2} \times 1.90 L}{373 K}\\P_{2} = \frac{1.34 atm \times 2.50 L \times 373}{308 K \times 1.90 L}\\= 2.14 atm[/tex]

Thus, we can conclude that the pressure is 2.14 atm if the gas was heated to 373 K and the volume decreased to 1.90 L.

Answer:

solution given:

Explanation:

4Fe +3O2------------>2Fe2O3

4mole. 3mole. 2 mole

224g. 96g. 320g

we have

224 g of fe needed to react completely with 96 g of O2

500g of fe needed to react completely with

96 ×500/224=214.3g of O2

214.3g of O2 is a required answer.

"The mass of [tex]O_{2}[/tex] will be 214.3g to completely react with 500 g of Fe."

What is mass?

A physical body's mass is the amount of matter it contains. It can also use to measure moment of inertia, or the resistance to movement when one net force is exerted. The degree of an object's gravitational pull to other bodies is also determined by its mass. The kilogram is the SI base unit of mass.

The reaction between Fe and [tex]O_{2}[/tex] can be written as:

[tex]4Fe+3O_{2}[/tex] → [tex]2Fe_{2}O_{3}[/tex]

It can be see that 4 mole of iron is reacts with 2 mole of oxygen and its form 2 mole of [tex]2Fe_{2}O_{3}[/tex]

So, 224 g of iron is needed in the reacted with oxygen (96 g).

500 g of iron will be needed = 96× 500/224= 214.3g of [tex]O_{2}[/tex].

Answer:

Sistema Nervioso Autónomo

Explanation:

El Sistema Nervioso es el encargado de enviar señales (impulsos nerviosos en su mayoría) a órganos y partes del cuerpo, para que ejerzan su función. En general, se compone de 3 divisiones o subsistemas:

Sistema Nervioso Central (cerebro y encéfalo)Sistema Nervioso Perisférico (nervios y ganglios)Sistema Nervioso Autónomo (impulsos involuntarios)

De éstos, el encargado de acciones y procesos involuntarios es el Sistema Nervioso Autónomo (SNA), que a su vez se divide en simpático y parasimpático. El SNA se encarga de los movimientos involuntarios de órganos, como el corazón, el sistema digestivo, etc., y de regular procesos como la secreción de hormonas y la regulación de la temperatura corporal.

Because if you get to the large mark it would be 5 but since its not at 5, it would be 6.1 as you can see in my drawing. It aligns perfectly with 6.1.

Answer:b

Explanation:

Lets take an example to explain this

Sodium(Na) has 1 electron in its outer or valence shell hence it will lose it and become a cation say to Chlorine(Cl)

To form Sodium Chloride.

Since it is capable of losing electrons, Sodium becoems a metal and has properties of metal

Whereas Chlorine which has 7 electrons in its valence shell gains an electrons to become an anion

Hence it is a non metal

And has the properties of an anion

Answer:

Yes, it is

Explanation:

Silicon (IV) oxide, commonly known as silica is a substance that majorly constitutes SAND. It has the chemical formula, SiO2, which contains a combination of silicon and oxygen.

The IUPAC name of SiO2 is Silicon IV oxide, which can also be referred to as Silicon dioxide because the structure the compound contains two (-di) oxygen atoms. Hence, based on the question, silicon(IV) oxide is the same as silicon dioxide.

Solution A

Explanation:

Solution A

1 mole of MgO = 24 + 16 = 40 g

? moles of MgO = 135.75g

[tex]\frac{135.75}{75}[/tex] = 1.81 moles

1.81 moles of MgO is in 2 liters of water

? moles of MgO is in 1 liter of water

[tex]\frac{1.584}{2}[/tex] = 0.905moles/liter or 0.905M

Solution B

1 mole of CaCl₂ = 40 + 35.5 = 75.5 g

? moles of CaCl₂ = 119.6g

[tex]\frac{119.6}{75.5}[/tex] = 1.584moles

1.584 moles of MgO is in 2 liters of water

? moles of MgO is in 1 liter of water

[tex]\frac{1.584}{2}[/tex]= 0.792moles/liter or 0.792M

Hello there!

In this case, since the radioactive decay kinetic model is based on the first-order kinetics whose integrated rate law is:

[tex]A=Ao*exp(-kt)[/tex]

We can firstly calculate the rate constant given the half-life as shown below:

[tex]k=\frac{ln(2)}{t_{1/2}} =\frac{ln(2)}{58year}=0.012year^{-1}[/tex]

Therefore, we can next plug in the rate constant, elapsed time and initial mass of the radioactive to obtain:

[tex]A=500g*exp(-0.012year^{-1} *30year)\\\\A=349g[/tex]

physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.

Answer:

Explanation:

Heat and temperature are two different but closely related concepts. Note that they have different units: temperature typically has units of degrees Celsius ( ∘ C ^\circ\text C ∘Cdegrees, start text, C, end text) or Kelvin ( Kstart text, K, end text), and heat has units of energy, Joules ( Jstart text, J, end text).

Answer:

So the total mass is 50 plus 150 grams the heat capacity 4.18 joules per gram per degree C. And the temperature change is 36 minus 25 and so we can calculate Delta H for the reaction that takes place.

Answer:

When an organism dies, it is usually destroyed by other forms of life and by weathering processes. On rare occasions some body parts—particularly hard ones such as shells, teeth, or bones—are preserved by being buried in mud or protected in some other way from predators and weather. Eventually, they may become petrified and preserved indefinitely with the rocks in which they are embedded. Methods such as radiometricdating—measuring the amounts of natural radioactive atoms that remain in certain minerals to determine the elapsed time since they were constituted—make it possible to estimate the time period when the rocks, and the fossils associated with them.

Answer:

Tomar 82 mL de solución concentrada y agregar agua hasta un volumen final de 1.0 L.

Explanation:

Tenemos una solución concentrada de hipoclorito de sodio, cuya concentración es 6.1%, por lo tanto:

Cc = 6.1 %

Y debemos hacer una dilucion para obtener una solucion diluida con:

Cd = 0.5%

Vd = 1.0 L

Por lo tanto, podemos usar la siguiente fórmula para calcular el volumen a tomar de solucion concentrada (Vc):

Cc x Vc = Cd x Vd

⇒ Vc = (Cd x Vd)/Cc = (0.5% x 1.0 L)/6.1% = 0.082 L

0.082 L x 1000 mL/1 L = 82 mL

Por lo tanto, para preparar la solución debemos tomar 82 mL de solucion concentrada de hipoclorito de sodio 6.1% y agregar agua hasta un volumen final de 1.0 L.

The volume of the container is 249.367 cm³

Explanation:

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space. In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance. Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

[tex]density=\frac{mass}{volume}[/tex]

From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

Density, according to the International System of Units, is usually expressed in kilogram per cubic meter (kg/m³) or gram per cubic centimeter (g/cm³).

In this case:

density= 0.790 g/cm³mass= 197 gvolume= ?

Replacing:

[tex]0.790 \frac{g}{cm^{3} } =\frac{197 g}{volume}[/tex]

Solving:

[tex]volume=\frac{197 g}{0.790 \frac{g}{cm^{3} } }[/tex]

volume= 249.367 cm³

The volume of the container is 249.367 cm³

Paso 1: Escribir la ecuación química balanceada

N₂ + 3 H₂ ⇒ 2 NH₃

Paso 2: Calcular el rendimiento teórico de NH₃ a partir de 140 g de N₂

En la ecuación balanceada, participan de N₂: 1 mol × 28.01 g/mol = 28.01 g y de NH₃: 2 mol × 17.03 g/mol = 34.06 g.

140 g N₂ × 34.06 g NH₃ /28.01 g N₂ = 170 g NH₃

Paso 3: Calcular el rendimiento porcentual de NH₃

El rendimiento experimental de NH₃ es 153 g. Podemos calcular el rendimiento porcentual usando la siguiente fórmula.

R% = rendimiento experimental / rendimiento teórico × 100%

R% = 153 g / 170 g × 100% = 90.0 %
