What is the percent composition of Phosphorus in Li3PO3

Answers

Answer:

you will get 17.983 g of lithium for every 100 g of lithium phosphate.

Explanation:

69.7%  is the percent by mass of Lithium in  Li[tex]_3[/tex]PO[tex]_3[/tex]. A percent is obtained by multiplying the result by 100.

One approach to show the concentration for an element within a compound or component in a combination is as a mass percentage. The mass percentage is computed by dividing the total weight of the combination by the mass of each component and multiplying the result by 100%. The mass percent is calculated by dividing the mass that contains the compound and solute by the mass for the element or solute.

99.795g/mol = molar mass of  Li[tex]_3[/tex]PO[tex]_3[/tex]

6.94g/mol = molar mass of Li

mass percentage of Li=(molar mass of Li/molar mass of Li[tex]_3[/tex]PO[tex]_3[/tex])×  100

=(6.94/99.7)×  100

=69.7%

Answer:

The missouri River is a Longesr tributary of the Mississippi River.

The Missouri River is tributary of the Mississippi River.

What is the Missouri River?

The Missouri River is known as the longest river in the United States. Missouri flows east and south for 2,341 miles before mixing with the Mississippi River north of St Louis, Missouri.

The river drains include parts of ten U.S. states and two Canadian provinces although a tributary of the Mississippi, the Missouri River is marginally longer and has a comparable volume of water. When combined with the lower Mississippi River, it creates the world's fourth-longest river system.

People depend on the Missouri River and its tributaries as a source of transportation and sustenance. The Missouri River was the main route for the westward expansion of the U.S. during the 19th century.

During the 20th century, the Missouri River was developed for irrigation, flood control, and the generation of hydroelectric power. Fifteen dams formed the stem of the river, with hundreds more on tributaries.

How many grams of MgO are in 3.500 moles?

Answers

(3.500 mol MgO)(40.3044g MgO/1mol MgO)
=141.0654

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, lead has the highest mass. 141.05gram of MgO are in 3.500 moles.

What is mole?

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number. 141.05gram is the mass of  MgO.

Mathematically, the molar mass, mole and given mass can be related as

Mole of MgO =given mass of  MgO ÷ molar mass of  MgO

Molar mass of MgO= 40.30 g/mol

Mole of MgO= 3.500 moles

substituting the values, we get

3.500 moles = mass of MgO÷ 40.30 g/mol

Mass of MgO=141.05gram

Therefore, 141.05gram of MgO are in 3.500 moles.

Factors used to speed up reactions

Solution

There are several factors that influence reaction kinetics :  

1. Concentration  

2. Surface area  

3. Temperature  

4. Catalyst  

5. Pressure  

6. Stirring  

Temperature is related to the kinetic energy of the particles. Heat is absorbed causes the particles of matter to move faster so that the reaction can take place faster

The enlarged surface area of the reactants causes more particles to react with other particles.

What is the attractive forces that hold particles together?We usually ranked the attractive forces that hold particles together while discussing them. Ionic bonds are the strongest, followed by hydrogen bonds that are somewhat weaker than that, and finally, his disciple disciple forces that are slightly weaker still. Then, Vander Wal's forces, also known as dispersion forces, are the weakest. The first one is ionic compounds, whereas the remaining three are frequently related to molecules or covalin compounds. Consequently, when comparing these attractive forces, the most accurate statement is is one of the first polar covalin bonds to form, resulting in dipole dipole forces. Let's call them polar covalin bonds, then. Van der Waals forces and polar covalin bonds are appealing on a weekly basis; these are the weakest.

Solution

Ideal gas law :

Given the following reaction, how many liters of H2 gas are needed to form 35.5 grams of NH3?

N2 + 3H2 -> 2NH3

Answers

Answer:

170.4L

Explanation:

The reaction equation is given as:

        N₂  +   3H₂  →    2NH₃  

Mass of NH₃    =  35.5g

Problem:

How many liters of H₂ are needed to produce 35.5g of NH₃  

Solution:

To solve this problem, let us find the number of moles of NH₃;

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

Molar mass of NH₃   = 14 + 3(1)  = 17g/mol

 So;

            Number of moles  = [tex]\frac{35.5}{17}[/tex]  = 5.07mole

From the balanced reaction equation:

               2 mole of NH₃   will be produced from 3 mole of H₂  

               5.07mole of NH₃ will produce  [tex]\frac{5.07 x 3}{2}[/tex]   = 7.61mole of H₂

At STP;

       1 mole of gas will occupy 22.4L

     7.61 mole of H₂ will occupy 7.61 x 22.4  = 170.4L

The ions S-2, Cl-1, K+, Ca+2, Sc+3 have the same total number of electrons as the noble gas argon. How would you expect the radii of these ions to vary?

Answers

Answer:

Cl^- <S^2-<Sc^3+ <Ca^2+<K^+

Explanation:

We know that ionic radius of ions decreases from right to left in the periodic table.  This is because, ionic radii decreases with increase in nuclear charge. This explains why; Sc^3+ <Ca^2+<K^+.

Secondly, even though Cl^- is isoelectronic with S^2-, the size of the nuclear charge in Cl^-  is larger compared to that of  S^2- . Hence Cl^-  is smaller than S^2- in ionic radius owing to increased nuclear attraction in Cl^-.
