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.

Ammonium dihydrogen phosphate, formed from the reaction of phosphoric acid with ammonia, is used as a crop fertilizer as well as
Tema [17]

Answer:

a)The mass percentages of nitrogen and phosphorus in the compound is 24.34% and 26.95% respectively.

b) 14.78 grams ammonia is incorporated into 100. g of compound.

Explanation:

a) Ammonium dihydrogen phosphate that is NH_6PO_4.

Molecular mass of ammonium dihydrogen phosphate = M

M = 115 g/mol

Percentage of an element in a compound:

\frac{\text{Number of atoms of element}\times \text{Atomic mass of element}}{\text{molecular mass of element}}\times 100

Percentage of nitrogen:

\frac{1\times 28 g/mol}{115 g/mol}\times 100=24.34\%

Percentage of phosphorus:

\frac{1\times 31g/mol}{115 g/mol}\times 100=26.95\%

b) Percentage of ammonia in 1 molecule of ammonium dihydrogen phosphate.

Molar mass of ammonia = 17 g/mol

\%=\frac{17 g/mol}{115 g/mol}\times 100=14.78\%

Amount of ammonia in 100 grams of compound:

14.78% of 100 g of ammonium dihydrogen phosphate:

\frac{14.78}{100}\times 100 g=14.78 g

14.78 grams ammonia is incorporated into 100. g of compound.

An isotope of cesium-137 has a half-life of 30 years. If 5.0g of cesium-137 decays over 60 years. How many grams will remain.
LenKa [72]

Answer:

1.25 gram of cesium-137 will remain.

Explanation:

Given data:

Half life of cesium-137 = 30 year

Mass of cesium-137 = 5.0 g

Mass remain after 60 years = ?

Solution:

Number of half lives passed = Time elapsed / half life

Number of half lives passed = 60 year / 30 year

Number of half lives passed = 2

At time zero = 5.0 g

At first half life = 5.0 g/2 = 2.5 g

At 2nd half life = 2.5 g/ 2 = 1.25 g

Thus. 1.25 gram of cesium-137 will remain.
