WILL GIVE BRAINLIST
In the Neighborhood
Ahn vigorously scrubbed windows, a tedious necessity for her family's new Vietnamese restaurant. They had turned the building from homely to gorgeous, but everything had to be absolutely perfect: unique decorations, skillful employees, and fabulous traditional food. Then customers would adore the place, making the business a success.

Ahn shifted her vision to look outside the restaurant as a girl about her age, with abundant red hair, strolled up the street. Ahn’s family had recently moved to this neighborhood, so she had few friends.

The girl paused to study the sign announcing their opening and then looked directly at Ahn with a friendly smile. Ahn smiled back shyly and lifted a hand, accidentally waving with the cleaning cloth. The girl laughed at her amusement and waved back in acknowledgment.

Ahn hesitated, not accustomed to initiating friendship, but she felt courageous, so on a whim she opened the door. "Hello," she said, adding the first thing that entered her head, "do you like Vietnamese food?"

"I don't know, but I like to try new things,” the girl remarked, and then she introduced herself as Gabriela.

Ahn could not think of additional conversation until she had a sudden idea. "Please wait here," she requested, "and I'll be right back." She ran into the adjoining kitchen and explained her idea to her father. He was sympathetic, so seconds later Ahn presented a small package to Gabriela. "Some Vietnamese candy for you to try,” she explained. “If you enjoy it, I hope you'll return to the restaurant sometime, or even visit after school when I'll be here preparing for the dinner service."

"Excellent, I'll see you around soon.” Gabriela headed down the street, glancing back with a cheerful wave. Ahn spent the remainder of the afternoon hoping Gabriela really would return and not think Ahn’s gift was weird.

The following day, Ahn assembled bouquets of artificial flowers, orchids that would never wilt. She was admiring her accomplishment when she heard unexpected tapping and turned to see Gabriela beckoning to her with a plate covered with transparent plastic wrap. Ahn grinned with enthusiasm and opened the door with a cordial greeting.


Gabriela presented the plate and said, "I brought biscuits made from my grandmother's recipe to thank you for the delicious candy.”

"Come in, and we can have some biscuits right now," Ahn stammered, happy inside.

Gabriela entered and rotated to scan the room with its picturesque landscape mural. "Thanks, they really are wonderful, and I'm fascinated to see your restaurant."

As they snacked on the treats, Ahn fumbled for conversation and considered an offer. "Are you good with vocabulary?” she inquired. "I intend to design a publicity pamphlet for the restaurant, and I could use some assistance."

"Certainly!" Gabriela said, adding, "I'm delighted you moved into the neighborhood and thrilled I have a new friend."

Ahn grinned, now positive that the restaurant would make a wondrous impression on the community, that customers would be plentiful, and that she was going to enjoy life here immensely

Answer:

The variable Q

Explanation:

i just took the test and got it right.... i hope this helps :)

The variable Q represents thermal energy in the equation Q = mcΔT. Hence, option B is correct.

The specific heat capacity is defined as the quantity of heat (J) absorbed per unit mass (kg) of the material when its temperature increases by 1 K (or 1 °C), and its units are J/(kg K) or J/(kg °C).

Q =  mcΔT

Q = heat energy

m = mass

c = specific heat capacity

ΔT = change in temperature

Hence, option B is correct.

Explanation:

¡Hola!

En este caso, para los problemas de equilibrio térmico, consideramos que la energía liberada por la sustancia que inicialmente está caliente (agua), es absorbida por la sustancia que inicialmente está fría (alcohol); thus, we can write:

[tex]Q_{agua}=-Q_{alcohol}[/tex]

La cual puede ser escrita en términos de masa, calor specifico y temperaturas:

[tex]m_{agua}C_{agua}(T_{EQ}-T_{agua})=-m_{alcohol}C_{alcohol}(T_{EQ}-T_{alcohol})[/tex]

De este modo, al resolver para la temperature de equilibrio térmico, obtenemos la siguiente expresión:

[tex]T_{EQ}=\frac{m_{agua}C_{agua}T_{agua}+m_{alcohol}C_{alcohol}T_{alcohol}}{m_{agua}C_{agua}+m_{alcohol}C_{alcohol}}[/tex]

Así, al reemplazar los valores en esta, obtenemos:

[tex]T_{EQ}=\frac{(20g)(1cal/g\°C)(40\°C)+(15g)(0.58cal/g\°C)(30\°C)}{(20g)*(1cal/g\°C)+(15g)(0.58cal/g\°C)} \\\\T_{EQ}=37\°C[/tex]

E. Particle emitted = gamma ray; protons gained = 0; Change in mass = 0

F. Particle emitted = alpha particle; Protons lost = 2; Change in mass = -4

Explanation:

Radioactivity is the spontaneous disintegration of nucleus of an atom resulting in emission of particles and radiation unyil a stable atomic nuclei is obtained. Substances that are exhibit radioactivity are known as radioactive substances and are usually isotopes of stable atoms.

The types of radiation emitted by a radioactive substances include alpha rays, beta rays, and gamma rays.

Alpha rays or particles are fast moving positively charged particles with a mass number of four and atomic number of two. Thus, each alpha particle is a helium nucleus.

Beta rays or particles are vary fast moving stream of electrons having a mass number of zero and a charge of -1.

Gamma rays are not particles but are electromagnetic waves similar to visible light and X-rays but with shorter wavelengths. They have no mass or charge.

An atom emitting alpha particles has its mass reducing by 4 units and its atomic number decreasing by 2.

An atom emitting beta particles as it decays has no change in mass but its atomic number increases by 1.

From the table:

A. Particle emitted = alpha particle; Protons lost = 2; Change in mass = -4

B. Particle emitted = alpha particle; Protons lost = 2; Change in mass = -4

C. Particle emitted = beta particles; protons gained = 1; Change in mass = 0

D. Particle emitted = alpha particle; Protons lost = 2; Change in mass = -4

E. Particle emitted = gamma ray; protons gained = 0; Change in mass = 0

F. Particle emitted = alpha particle; Protons lost = 2; Change in mass = -4

Explanation:

A chemical reaction produced a new substance. In a chemical reaction, the atoms that make up the reactants are rearranged to produce various products.

chemical reaction, the transformation of one or more chemicals (the reactants) into one or more distinct compounds (the products). Chemical elements or chemical compounds make up substances.

A chemical reaction is one in which  two or more reactants will react to form a new substance. When new substance will form it will produce heat. Therefore, when science teacher was mixing two liquids it was generating heat.

Heating a substance allow molecules to move faster. When heat is given to the object it will move fast. When heat will apply to a solid it will turn into liquid. When heat is supplied to the liquid it will turn into gas.

Therefore, A chemical reaction produced a new substance. In a chemical reaction, the atoms that make up the reactants are rearranged to produce various products.

Answer:

D. 18g

Explanation:

To get the answer, we will use an equation to convert the grams of C2H5OH to moles of C2H5OH, then I will convert the moles of C2H5OH to moles of CO2, and then I will convert the moles of CO2 to grams of CO2.

9.2g C2H5OH / 46.07g C2H5OH = 0.199 mol C2H5OH

0.199 mol C2H5OH (2 mol CO2 / 1 mol C2H5OH) = 0.398 mol CO2

0.398 mol CO2 (44.01g CO2 / 1 mol CO2) = 17.515g CO2

The answer closest to our answer is answer choice D. 18g

Therefore, the answer is D

In normal temperatures, carbon dioxide is a colorless, non-flammable gas, its calculated value is "18 gram".

Equation:

[tex]\to \bold{C_2H_5OH\ (l)+3O_2\ (g) \to 2CO_2\ (g)+3H_2O\ (g)}[/tex]

In the above-given scenario, We'll utilize an equation that converts grams of ethanol to moles of ethanol, then converts moles of ethanol to moles of carbon dioxide, and finally, transforms the moles of carbon dioxide into grams of carbon dioxide to get the result.

Following are the calculation of the conversion of carbon dioxide:

[tex]\to \frac{9.2\ g\ C_2H_5OH }{46.07\ g\ C_2H_5OH} = 0.199\ mol C_2H_5OH\\\\\to 0.199\ mol\ C_2H_5OH \ (\frac{2\ mol\ CO_2}{ 1\ mol\ C_2H_5OH}) = 0.398\ mol\ CO_2\\\\\to 0.398\ mol \ CO_2 \ (\frac{44.01\ g\ CO_2}{1 \ mol\ CO_2}) = 17.515\ g\ CO_2 \approx 18\ g \ CO_2\\\\[/tex]

Therefore, the answer is "Option D".

Answer:

The volume of the gas will be 814 mL.

Explanation:

An ideal gas is a theoretical gas that is considered to be composed of point particles that move randomly and do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.

The gas laws are a set of chemical and physical laws that allow determining the behavior of gases in a closed system. The parameters evaluated in these laws are pressure, volume, temperature and moles.

Charles's Law consists of the relationship that exists between the volume and the temperature of a certain quantity of ideal gas, which is kept at a constant pressure, by means of a constant of proportionality that is applied directly. For a given sum of gas at a constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases because the temperature is directly related to the energy of the movement of the gas molecules. .

In summary, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:  

[tex]\frac{V}{T} =k[/tex]

It is desired to study two different states, an initial state and an final state. You have a gas that is at a volume V1 and at a temperature T1 at the beginning of the experiment. When the temperature varies to a new T2 value, then the volume will change to V2, and the following will be true:

[tex]\frac{V1}{T1} =\frac{V2}{T2}[/tex]

In this case:

Replacing:

[tex]\frac{752 mL}{298 K} =\frac{V2}{323 K}[/tex]

Solving:

[tex]V2= 323 K*\frac{752 mL}{298 K}[/tex]

V2= 815 mL

The volume of the gas will be 814 mL.
