Here is Beck's address:

777dan777 [17]

Hi! My answer would be D, USA.

Explanation:

We are provided with 5 pieces of an address. They are as followed.

12 Riverdale Lane, Apartment A, San Jose, California, and USA.

Imagine each of the five parts of Beck's address represents Earth, the Milky Way, the moon, the solar system, or the universe, based on their sizes. Which of the following parts of Beck's address would represent the solar system?

If we have to plug in Earth, the Milky Way, the moon, the solar system, and the universe, (all based on size,) we would first start with what "Apartment A" would be in this scenario. Apartment A is the smallest piece we have to work with, and so is the moon. This leads me to believe that the Moon should be plugged into Apartment A. Now, 12 Riverdale Lane is most likely going to be the Earth, since it is the second smallest one on our list. San Jose would turn into the Sun, California represents the Milky Way, and USA represents the solar system.

I sincerely hope I helped!

Have a wonderful day :)

A gas has a pressure of 1.34 atm when the temperature is 237K. The gas is then heated until the temperature measures 312K. What

alexandr1967 [171]

The answer for the following question is answered below.

<em><u>Therefore the new pressure of the gas is 1.76 atm.</u></em>

Explanation:

Given:

Initial pressure of the gas = 1.34 atm

Initial temperature of the gas = 273 K

final temperature of the gas = 312 K

To solve:

Final temperature of the gas

We know;

From the ideal gas equation

P × V = n × R × T

So;

from the above equation we can say that

<em>P ∝ T</em>

$\frac{P}{T}$ = constant

$\frac{P_{1} }{P_{2} }$ = $\frac{T_{1} }{T_{2} }$

Where;

$P_{1}$ = initial pressure of a gas

$P_{2}$ = final pressure of a gas

$T_{1}$ = initial temperature of a gas

$T_{2}$ = final temperature of a gas

$P_{2}$ = $\frac{1.34*312}{237}$

$P_{2}$ = 1.76 atm

<em><u>Therefore the new pressure of the gas is 1.76 atm.</u></em>

What is the molar mass of (NH4)2S

Anastaziya [24]

Answer:

This compound is Ammonium Sulphide and has molar mass 68 g/mol.

Explanation:

Molar Mass : It is the mass of 1 mole of the substance and in grams.Its units are gram/mole.

It is numerically equal to mass of the substance in atomic mass units

How to calculate Molar mass :

$(NH_{4})_{2}S = 2(atomic\ mass\ of\ N + 4\times mass\ of\ H ) +atomic\ mass\ of\ S$

$(NH_{4})_{2}S = 2(14 + 4(1) ) + 32$

$(NH_{4})_{2}S = 2(14 + 4 ) + 32$

$(NH_{4})_{2}S = 2(18) + 32$

$(NH_{4})_{2}S = 36 + 32$

$(NH_{4})_{2}S = 68$ grams/mole

Molar mass of Ammonium sulphide is 68 g/mol
