Determine the number of grams in each of the quantities

1.39.0 x 1024 molecules Cl2

Answers

Mass of Cl₂ : 164.01 g

Further explanation

A mole is a number of particles(atoms, molecules, ions)  in a substance

This refers to the atomic total of the 12 gr C-12  which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles  

Can be formulated :

N = n x No

N = number of particles

n = mol

No = 6.02.10²³ = Avogadro's number

mol Cl₂ :

[tex]\tt n=\dfrac{N}{No}\\\\n=\dfrac{1.39.10^{24}}{6.02.10^{23}}\\\\n=2.31[/tex]

Why reaction between phosphorus and oxygen produces four atoms of phosphorus and five atoms of oxygen

Answers

Answer:

Reaction between an oxygen and  a phosphorus will produce oxides of phosphorus.

Explanation:

Reaction between oxygen and phosphorus produces four atoms of phosphorus with five atoms of oxygen. Sometimes it produces two atoms of phosphorus and five atoms of oxygen and sometimes four atoms of phosphorus and six atoms of oxygen. It does so depending upon the availability of oxygen. The size of phosphorus atom  interferes with the ability to form a double bonds to the other elements, such as nitrogen, oxygen, etc.

What kind of bond would form between an iron and an oxygen atom: ionic, covalent, or metallic? What kind of bond would form between two silver atoms: ionic, covalent, or metallic? What happens to the valence electrons in this bond? How do ionization energy and electronegativity help explain why this occurs? 3) What kind of bond would form between two chlorine atoms: ionic, covalent, or metallic? What happens to the valence electrons in this bond? How do ionization energy and electronegativity help explain why this occurs?

Answers

Answer:

See explanation

Explanation:

Since iron is a metal and oxygen is a non metal, a bond is formed between the two when electrons are transferred from iron to oxygen. Hence the bond is ionic.

Two silver atoms are held together by metallic bonds. Metallic bond are bond forces that exist between metal atoms in a crystal lattice. The valence electrons in this bond form a cloud. Metals have low ionization energy and low electronegativity hence they loose electrons easily. This accounts for the nature of the metallic bond.

The bond formed between two chlorine atoms is a covalent bond. The valence electrons in this bond are localized between the two chlorine atoms. Chlorine is a nonmetal hence it has a high ionization energy and high electronegativity. Hence it forms covalent bonds in which electrons are shared between bonding atoms.

According to Le Chatelier's principle, what happens to the equilibrium constant (K) when the concentration of the reactants is doubled? The value of the equilibrium constant (K) is doubled. The value of the equilibrium constant (K) is halved. The value of the equilibrium constant (K) remains the same. The value of the equilibrium constant (K) changes unpredictably.

Answers

Answer:

The value of the equilibrium constant (K) remains the same.

Explanation:

A state of dynamic equilibrium is said to have been achieved in a reaction system when the rate of forward reaction equals the rate of reverse reaction.

At equilibrium, doubling the initial concentration of reactants have no effect on the equilibrium constant K. The equilibrium will rather shift to the left or right as required in order to annul the constraint.

Using the electronegativity chart below, determine which compound would have the highest polarization

A. Li-O
B. B-F
C. H-CI
D. Be-Br

Answers

Answer:

A. Li-O

Explanation:

The highest polarization will occur between the atoms of  Li-O because they have the most electronegativity difference between them.

Polarization occurs when there is a separation of charge between the atoms of heteronuclear molecules.

The electronegativity gives the tendency for an atom to attract the electrons within the bond pair to itself.

To know the atom with most polarization, it has to be one with highest electronegativity difference. Li and O have the highest difference. Also, since the bond is between a metal and non-metal, it is obviously the most polarized.

Explain why a) Kl (potassium iodide) dissolves in water, but b) it will not dissolve in
hexane.

Answers

Answer:

Explanation: Brief description of demonstration

Three clear liquids form three distinct layers in a cylinder. Iodine crystals sprinkled on the top layer sink and form pink solutions with the top and bottom layers but do not dissolve in the middle. When the liquids are mixed, two layers form: a pink layer on the bottom, and a colorless layer on top. When white potassium iodide crystals are added and the liquids are mixed again, the colorless layer turns yellow.

Concepts illustrated:

• Phases and phase boundaries (surfaces)

• Density

• Polar/non-polar (hydrophilic/hydrophobic) interactions

• Solubility, miscibility

• Chemical reaction

• Extraction

• [Solution and emulsion]

Materials

• Clear glass reaction cylinder or gas-washing bottle, at least 200 mm tall, with ground glass stopper (A cylindrical container is preferable to a separatory funnel for this experiment. The stopper must be non- reactive, and, to prevent a potentially dangerous pressure build-up, the stopper must be easily released. For a very small class, a large test tube with a suitable stopper is adequate. )

• Equal volumes of chloroform, water, and hexane (The volume of each liquid should be a little more than one-fourth the volume of the cylinder.)

• Iodine crystals and small spatula

• Potassium iodide crystals and medium spatula

Preparation

Work in a hood. Pour the chloroform into the reaction cylinder. Add the water and allow the liquids to separate completely. (If necessary, speed the process by holding the cylinder vertical and gently swirling the solution with a circular motion.) Tip the cylinder and pour the hexane slowly down the side to prevent mixing. Close the cylinder and set it aside, away from sources of heat, until time for the demonstration.

Answer:It forms single phase mixtures (solutions) with other polar and ionic substances. ... Since water is less dense than this non-polar mixture, the bubbles rise to the top. Potassium iodide, an ionic compound, dissolves easily in water but does not dissolve in chloroform and hexane.

EXPLAIN What is one way that the thermal energy of a system can be changed?

Answers

Answer:

When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.

Explanation:

BTW I GOT THE ANSWER FROM KRISTINA

The thermal energy of a system is the amount of heat energy in it.

One way to change thermal energy is by alter the system by introducing a new object to the system.

The thermal energy of a system is calculated using:

[tex]E = \frac 12 mc\theta[/tex]

Assume the mass of the system remains unchanged.

When an object is introduced to the system, the thermal energy becomes:

[tex]E_2 = \frac 12 mc(\theta + \alpha)[/tex]

Where:

[tex]\alpha \ne 0[/tex] --- the temperature of the object.

Expand:

[tex]E_2 = \frac 12 mc(\theta) + \frac 12 mc (\alpha)[/tex]

Substitute: [tex]E = \frac 12 mc\theta[/tex]

[tex]E_2 = E + \frac 12 mc (\alpha)[/tex]

This means that the thermal energy of the system will change by the thermal energy of the object that is being introduced to the system.

Hence, one way the thermal energy can be changed is to introduce a new object (or matter).

12.4 g of phosphorus reacts with 9.6 g of oxygen.
Which of the following chemical equation represents this reaction?
[Relative atomic mass: P, 31; 0, 16]
A P + O2 + PO2
B 2 P + O2 + 2 PO
C 3P +2 02 → P304
D 4P +3 02 → 2 P203​

Answers

Answer:

D 4P +3O₂ → 2 P₂O₃

Explanation:

In this problem, we need to convert the mass of phosphorus and oxygen to moles trying to find the ratio of reaction (The moles of P that reacts per mole of O₂):

Moles P:

12.4g P * (1mol P / 31g) = 0.4 moles

Moles O₂:

9.6g * (1mol / 32g) = 0.3 moles

The ratio of reaction is:

0.4 mol / 0.3 mol = 1.33 = 4 moles of P / 3 moles of O₂

That means 4 moles of P react with 3 moles of O₂ and the reaction that represents this ratio is:

D 4P +3O₂ → 2 P₂O₃

The reaction of 12.4 g Phosphorous with 9.6 grams of Oxygen will be represented as [tex]\rm 4\;P\;+\;3\;O_2\;\rightarrow\;2\;P_2O_3[/tex]

In a chemical equation, the stoichiometric values are the moles of the molecules involved in the reaction. For the reaction of Phosphorous and oxygen, the moles of both elements are to be calculated.

Moles = [tex]\rm \frac{weight}{molecular\;weight}[/tex]

Moles of Phosphorous = [tex]\rm \frac{12.4}{31}[/tex]

Moles of Phosphorous = 0.4

Moles of oxygen = [tex]\rm \frac{9.6}{16}[/tex]

Moles of oxygen = 0.6

Moles of [tex]\rm O_2[/tex] = 0.3

The equation will be:

[tex]\rm 0.4\;P\;+\;0.3\;O_2\;\rightarrow\;2\;P_2O_3[/tex]

[tex]\rm 4\;P\;+\;3\;O_2\;\rightarrow\;2\;P_2O_3[/tex]

The correct reaction will be D.
