Math each description below with the following microscopic pictures(pls help!!!!!)

Chemistry

The microscopic pictures i, iii, iv, v, and vi are associated with the descriptions a, d, a, c, and b, respectively. Picture ii <u>does not match</u> with the given options.    

To associate each description with the pictures we need to remember that:

  • Gas is a state in which atoms or molecules move freely around. The gases tend to expand to occupy all the space of the container.    
  • A solid is a state in which the <em>atoms </em>or <em>molecules </em>are very close to each other and cannot move freely, so they will not tend to occupy all the space as the gases do.

 

Now, let's evaluate each description.

<u>Picture i</u>

In this image, we can see the movement of diatomic gases (or gaseous compounds) composed of the same element. An example of this can be nitrogen gas (N₂), oxygen gas (O₂), hydrogen gas (H₂), and others.  

So, this is related to option a: <u>a gaseous compound</u>.

 

<u>Picture ii</u>  

In this, we can see a mixture of gaseous compounds composed of different elements, denoted by different colors (blue and orange). An example can be the mixture of monoxide carbide (CO) with nitrogen (N₂).

Hence, this is associated with a mixture of two gaseous compounds. There is no option related to this image.  

<u>Picture iii</u>

In the image, we can see a mixture of monoatomic and diatomic gases. The <em>diatomic gases</em> are composed of <em>two different elements</em> (blue and orange colors).

Therefore, this is related to option d:<em> </em><u>a mixture of gaseous elements and gaseous compounds</u>.

<u>Picture iv</u>

This image is similar to picture i, but in this, the gaseous compounds are composed of two different elements.

Hence, this description is related to option a: <u>a gaseous compound</u>.

<u>Picture v</u>

In this, we can see that the <em>atoms </em>are <em>close to each other</em>, which corresponds to a solid-state.

Then, this is related to option c: <u>a solid element.</u>

<u>Picture vi</u>

We can see the presence of a mixture of two gaseous elements (both monoatomics), because of the two different colors.

So, this is related to option b: <u>a mixture of two gaseous elements</u>.  

Therefore, the descriptions of the pictures i, iii, iv, v, and vi are related to options a, d, a, c, and b, respectively. Picture ii does not match with the given options.

X = 59,29g CH₃COOH

We used 70g CH₃COOH, it' too much.
So, acetic acid is excess reagent, and sodium bicarbonate is limiting reagent.
_______________________________
B) Amount of CH3COOH is in excess.

Determine the final concentration when 250mL of 3M solution is dilluted to a final volume of 850mL. (Enter Number)​
LenKa [72]

Answer:

M₂ = 0.9 M

Explanation:

Given data:

Initial Volume = V₁ = 250 mL

Initial molarity = M₁= 3 M

Final volume = 850 mL

Final molarity = ?

Solution:

M₁V₁ = M₂V₂

M₂ = M₁V₁ /V₂

M₂ = 3 M × 250 mL / 850 mL

M₂ = 750 M / 850

M₂ = 0.9 M

At STP, which gas sample has a volume of 11.2 liters?
Natasha2012 [34]

Answer:

0.500 moles of CO2 has a volume of 11.2 L at STP (option B)

Explanation:

Step 1: Data given

Volume of a gas at STP = 11.2 L

STP: Pressure = 1 atm  and temperature = 273 K

Step 2: Calculate volume

p*V= n*R*T

V = (n*R*T)/p

⇒with V = the volume of the gas = TO BE DETERMINED

⇒with n = the number of moles of the gas

⇒with R = the gas constant = 0.08206 L*atm/mol*K

⇒with T = the temperature = 273 K

⇒with p = the pressure of the gas = 1 atm

A ) 0.250 mole of NH3

V = (0.250 * 0.08206 * 273) / 1

V = 5.6 L

B ) 0.500 mole of CO2

V = (0.500 * 0.08206 * 273) / 1

V = 11.2 L

C ) 0.750 mole of NH3

V = (0.750 * 0.08206 * 273) / 1

V = 16.8 L

D) 1.00 mole of CO2

V = (1.00 * 0.08206* 273) / 1

V = 22.4 L

0.500 moles of CO2 has a volume of 11.2 L at STP (option B)
