The (15-35-15) number on a bag of fertilizer is calculated by an outdated method. All modern fertilizers use PO43- as a source of phosphorus. Use your knowledge of the old methods to determine the moles of phosphorus found in 10.0 grams of (15-35-15)?

Answers

The (15-35-15) number on a bag of fertilizer is calculated by an outdated method.  Using the knowledge of the old methods, the number of moles of phosphorus found in 10.0 grams of phosphorus is 0.05 mole.

The (15-35-15) number on the bag of fertilizer is used for:

Nitrogen 15 : Phosphorus pentoxide 35: potassium oxide 15

Thus, in a 100-gram bag of fertilizer, there are 35 grams of phosphorus pentoxide P₂O₅.

To determine the number of moles of 10 grams of phosphorus pentoxide in (15-35-15) bag of fertilizer, we have:

[tex]\mathbf{=10 \times \dfrac{35}{100} \ grams \ of \ P_2O_5}[/tex]

= 3.5 grams of P₂O₅

Recall that:

[tex]\mathbf{Number of moles = \dfrac{mass}{molar \ mass}}[/tex]

the molar mass of P₂O₅ = 142 g/mol

[tex]\mathbf{Number of moles = \dfrac{3.5\ g}{ 142 \ g/mol}}[/tex]

[tex]\mathbf{Number of moles = 0.0246 \ mol}[/tex]

Provided that 1 mole of P₂O₅ harbors 2 moles of phosphorus;

Then;

The number of phosphorus present in 10.0 grams of (15-35-15) fertilizer is:

= 0.0246 moles × 2

= 0.0492 moles

≅ 0.05 moles

Therefore, we can conclude that the number of moles of phosphorus found in 10.0 grams of  (15-35-15) bag of fertilizer is 0.05 moles.

The cell membrane can be a fence or wall around the city because it controls what enters and leaves the cell, and separates the cell from the outside.

The nucleus could be the city hall because it  protects DNA and controls the cell (city)

The mitochondria could be the greenhouse because it makes ATP energy from sugar + 02

The chloroplasts could be a farm or garden because it is where photosynthesis takes place and makes energy + sugar from sunlight

The ribosomes could be the factory to make stuff because it makes proteins

The endoplasmic reticulum could be a kitchen or restaurant because it helps finish proteins, and makes membranes.

Molybdenum can form a wide series of halide compounds, including four different fluoride compounds. The percent by mass of molybdenum in the four compounds is 63.0%,
56.0%,
50.0%,
and 46.0%.
Determine the formula and name for each of the four different molybdenum fluorides.

Answers

The formula and names of the compounds are:

1. Formula of compound => MoF₃

Name of compound => Molybdenum trifluoride

2. Formula of compound => MoF₄

Name of compound => Molybdenum tetrafluoride

3. Formula of compound => MoF₅

Name of compound => Molybdenum pentafluoride  

4. Formula of compound => MoF₆

Name of compound => Molybdenum hexafluoride  

1. Determination of the name and formula of the molybdenum fluoride having 63.0% of molybdenum.

Molybdenum (Mo) = 63.0%

Fluorine (F) = 100 – 63 = 37%

Formula =?

Mo = 63.0%

F = 37%

Divide by their molar mass

Mo = 63.0 / 96 = 0.656

F = 37 / 19 = 1.947

Divide by the smallest

Mo = 0.656 / 0.656 = 1

F = 1.947 / 0.656 = 3

Therefore,

Formula of compound => MoF₃

Name of compound => Molybdenum trifluoride

2. Determination of the name and formula of the molybdenum fluoride having 56.0% of molybdenum.

Molybdenum (Mo) = 56.0%,

Fluorine (F) = 100 – 56 = 44%

Formula =?

Mo = 56%

F = 44%

Divide by their molar mass

Mo = 56 / 96 = 0.583

F = 44 / 19 = 2.316

Divide by the smallest

Mo = 0.583 / 0.583 = 1

F = 2.316 / 0.583 = 4

Therefore,

Formula of compound => MoF₄

Name of compound => Molybdenum tetrafluoride

3. Determination of the name and formula of the molybdenum fluoride having 50.0% of molybdenum.

Molybdenum (Mo) = 50.0%,

Fluorine (F) = 100 – 50 = 50%

Formula =?

Mo = 50%

F = 50%

Divide by their molar mass

Mo = 50 / 96 = 0.520

F = 50 / 19 = 2.632

Divide by the smallest

Mo = 0.520 / 0.520 = 1

F = 2.632 / 0.520 = 5

Therefore,

Formula of compound => MoF₅

Name of compound => Molybdenum pentafluoride  

4. Determination of the name and formula of the molybdenum fluoride having 46.0% of molybdenum.

Molybdenum (Mo) = 46.0%,

Fluorine (F) = 100 – 46 = 54%

Formula =?

Mo = 46%

F = 54%

Divide by their molar mass

Mo = 46 / 96 = 0.479

F = 54 / 19 = 2.842

Divide by the smallest

Mo = 0.479 / 0.479 = 1

F = 2.842 / 0.479 = 6

Explanation:

2C2H6 + 7O2 = 4CO2 + 6H2O

2C2H2 + 5O2 = 4CO2 + 2H2O

A lot of this is trial and error.  I start from left to right.  For the first reaction, you had

C2H6 + O2  =  CO2  +  H2O

You have 2 carbons on the left so you can try adding a 2 in front of the carbons on the right and keep going from there.  Now you have

C2H6  +  O2  =  2CO2  + H2O

You now have 2 C on each side.  C2 is the same as 2C.

The next step is to look at the hydrogens on the left.  You have 6 so you need 6 on the right.  You can add a 3 in front of the H on the right.  The H already has a subscript of a 2 so having the 3 in front will now make it 6H.  You now have this

C2H6  +  O2  =  2CO2  +  3H2O

So your C are equal (2 on each side) and your H is equal (6 on each side).  All that is left is the O.  So far you have 2 on the left but you have 7 on the right (4 from the 2CO2 and 3 more from 3H2O).  Since you have an even number on one side and an odd number on the other, there is no way to make this work.  So it's time to start over.

My next step was to put a 2 in front of C2H6 and keep going as we did above.  Start with this

2C2H6   + O2  = CO2  + H2O

You have 4 C on the left.  So you need to add a 4 in front of CO2 to get 4 C on the right.  Now you have this

2C2H6  +  O2  =  4CO2  +  H2O

Now on the left you have 12 H (2 in front times the 6 subscript on the H).  You need to have 12 on the right.  We can get that by putting a 6 in front of the H2O ( again the 6 in front times the 2 subscript of the H is 12 total).  You have this now

2C2H6  +  O2  = 4CO2  +  6H2O

You now have 4 C on both sides, 12 H on both sides.  All that is left now is the O.

On the right side, you have a total of 14 ( 8 from the 4CO2 and 6 from 6H2O).  So you'd need to add 7 in front of the O2 to make it 14.

You're done.  4 C on both sides, 12 H on both sides and 14 O on both sides.

The second equation I just did the same process.

Describe the relationship between the state of matter of water (gas, liquid, solid) and the motion of the water molecules

Answers

Water has three states of matter namely gas, solid or ice form and liquid. Molecules in solid state are not able to move since they are tightly packed.

Molecules can move in liquid state and they moves easily in gaseous state.

What is states of matter?

Every substance have three states, that are gas, liquid and solid. In solid state, molecules are tightly packed and are unable to move apart. In liquid state, molecules have some space to move and motion of liquid is easy.

The movement of molecules in a substance depends on the space allotted for them or called the volume. More volume between molecules, easy to move apart.

Gaseous state is composed of molecules located far apart from each other and they diffuse easily. Therefore, motion in three states of water is different and moves faster in gaseous state.

Explanation:

Congestive heart failure happens when your heart gets too weak to pump blood from the lungs out to the body. Pressure builds up in the heart which puts pressure on the blood vessels of the lungs. This will lead to leakage of the vessels and the fluids build up in the air sacs of the lungs. This condition is called pulmonary edema.

Pulmonary edema occurs when fluid builds up in the lungs making it hard to breathe. It may start out as running out of breath easily but if left untreated (both conditions) symptoms get worse over time.

The product of this reaction is PH3. All of the atoms in PH3 have a stable configuration.

According to the octet rule, atoms are stable when they have two or eight electrons around their outermost shell. A stable configuration is one in which the outermost shell is fully filled with eight electrons.

The reason behind chemical combination is to enable atoms attain this stable configuration. If we look at the compound, PH3, we will notice that phosphorus has eight electrons around its outermost shell while each hydrogen atom has two electrons around its outermost shell hence  all of the atoms have a stable configuration.
