Answer 1

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 2.66 mole of Al[tex]_2[/tex]O[tex]_3[/tex] form when 4.0 mol O[tex]_2[/tex] reacts.

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. The stoichiometry represents the number of moles.

4AI + 3O[tex]_2[/tex]→ 2Al[tex]_2[/tex]O[tex]_3[/tex]

moles of  Al =6.0 mol

moles of  O[tex]_2[/tex]=4.0 mol

Since oxygen is limiting reagent

moles of Al[tex]_2[/tex]O[tex]_3[/tex]=2/3×4.0

                       =2.66 mole

Therefore, 2.66 mole of Al[tex]_2[/tex]O[tex]_3[/tex] form when 4.0 mol O[tex]_2[/tex] reacts.

A vessel is filled with a gas at a temperature of 30 degree celsius and operator of 67cm mercury calculate the final pressure of the volume of the gas is doubled it is heated to 80degree celcious​

Answers

The final pressure is 6312.935 Pa.

The final pressure of the gas can be calculated using the Ideal Gas Law, PV = nRT.

In this situation, the volume of the gas is doubled and the temperature is increased from 30 degrees Celsius to 80 degrees Celsius, while the number of moles of gas and the ideal gas constant remains constant.

Therefore, the pressure of the gas will decrease as the volume doubles and the temperature increases. The final pressure can be calculated by multiplying the initial pressure by the ratio of the initial volume to the final volume and the ratio of the final temperature to the initial temperature.

Final pressure = (Initial pressure) x (Initial volume / Final volume) x (Final temperature / Initial temperature)

The initial pressure is 67cm mercury. 1cm mercury = 133.322 Pa so 67cm mercury = 67*133.322 =8933.294 Pa.

The final temperature is 80-degree celsius = 80+273 = 353K

The final pressure =8933.294 x (1/2) x (353/303) = 6312.935 Pa

Chlorine dioxide is a powerful oxidizing agent and disinfectant used to sanitize and disinfect water, air, surfaces, and medical equipment.

Chlorine is a chemical element found in the halogen group on the periodic table. It has the atomic symbol Cl, and its atomic number is 17. Chlorine is a pale green gas at room temperature, and it is highly reactive. Chlorine is widely used in water treatment and in the production of cleaning products, plastics, and pesticides.

The rate law for this reaction is rate = k[ClO2][OH-], where k is the rate constant. To calculate the rate constant, we can use the following equation:

k = (rate2 - rate1)/([ClO2]2 - [ClO2]1)([OH-]2 - [OH-]1)

Substituting the values for experiments 1 and 2, we get:

k = (0.00276 - 0.0248)/((0.020 - 0.060)(0.030 - 0.030)) = -0.142

The value of the rate constant is k = -0.142 mol/((L s)mol2).

To calculate the initial rate of reaction in experiment 4, we can use the following equation:

rate = k[ClO2][OH-]

Substituting the values for experiment 4, we get:

List some of the methods used to prevent or slow corrosion with detailed explanation

Answers

Answer:

There are several methods that can be used to prevent or slow corrosion:

Coatings: Applying a protective coating to a metal surface can prevent corrosion by creating a barrier between the metal and the environment. Common types of coatings include paint, galvanizing, and electroplating.

Cathodic protection: Cathodic protection involves applying a current to a metal surface in order to reduce the potential difference between the metal and its environment. This can help to prevent corrosion by reducing the electron flow that drives the corrosion reaction.

Inhibitors: Corrosion inhibitors are chemical substances that can be applied to a metal surface to slow or prevent corrosion. These substances work by reacting with the metal surface or the environment to form a protective film or layer.

Passivation: Passivation is a process that involves removing surface contaminants and oxide layers from a metal surface in order to improve its corrosion resistance. This can be achieved through chemical or mechanical means.

Materials selection: Choosing corrosion-resistant materials for specific applications can help to prevent or slow corrosion. For example, stainless steel is a commonly used material for corrosive environments because of its high resistance to corrosion.

Environmental control: Controlling the environment in which a metal object is used can also help to prevent or slow corrosion. For example, reducing humidity or keeping a metal object dry can help to prevent corrosion.

Maintenance: Regular maintenance, such as cleaning and inspection, can help to identify and address corrosion issues before they become severe. This can include removing corrosion products, repairing damage, and applying protective coatings as needed.

What will be the pH of solution after sodium acetate solution in the middle or the last column reacts with the specified concentration of HCl

Answers

The pH of the final solution will be less than 7, but closer to 7 if the initial concentration of sodium acetate is high and the concentration of HCl is low.

The pH of a solution after a reaction with a strong acid like HCl will depend on the concentration of the acid and the concentration of the acetate ions (CH3COO-) in the sodium acetate solution. Sodium acetate (CH3COONa) is a weak base, and when it reacts with HCl, it forms acetic acid (CH3COOH) and sodium chloride (NaCl). The equation for this reaction is: CH3COONa + HCl → CH3COOH + NaClThe pH of a solution is a measure of the concentration of hydronium ions (H3O+) in the solution, so the pH of the solution after the reaction will depend on the concentration of H3O+ ions and the concentration of acetate ions. If the reaction is done in aqueous solution, the acetic acid formed will dissociate to form H3O+ and acetate ions. The acetate ions will neutralize some of the H3O+ ions, thus decreasing the overall acidity of the solution. The pH of the final solution will be less than 7, but closer to 7 if the initial concentration of sodium acetate is high and the concentration of HCl is low. It's important to note that without knowing the initial concentration of sodium acetate and the volume of the solutions it is not possible to determine the final pH.

Answers

The mass of water needed to prepare 45 g of salt solution if the salt content in the solution is 12% is 330g.

The solute is the thing that needs to dissolve, and the solvent is the thing that needs to dissolve it. With a wide variety of solutes and solvents, solutions can be created. We are aware of a wide range of solutions.

Given,

Mass of the salt solution (Solute) = 45g

salt content in the solution = 12%

Let Mass of water = x

Total mass of solution = 45 + x

Concentration of solution = Mass of solute / Mass of Solution × 100

12 = 45 / 45 + x × 100

⇒ 12/100 = 45 / 45 + x

⇒ 0.12 = 45 / 45 + x

⇒ 0.12 (45 + x) = 45

⇒ 5.4 + 0.12x = 45

⇒ 0.12x = 45 - 5.4

The arrangement of the particles in a substance affects its properties because the arrangement of the particles determines the interactions between the particles.

The arrangement of the particles affects the properties of a substance because the interactions between the particles determine the overall characteristics of the substance.

For example, if the particles in a substance are arranged in an orderly, crystalline structure, the inter-particle forces are strong, making the material harder and more rigid. On the other hand, if the particles are arranged in a disordered, amorphous structure, the inter-particle forces are weaker, making the material softer and more malleable.

The arrangement of the particles also affects the physical and chemical properties of the substance. If the particles are arranged in a crystalline structure, the substance will have a higher melting point, boiling point, and hardness than if the particles were arranged in an amorphous structure.

However, assuming they contain equal energy, both fully-filled and half-filled orbitals can participate in this process.

When two atomic orbitals unite to generate a hybrid orbital in a molecule, the energy of the orbitals of the individual atoms is redistributed to give orbitals of equivalent energy.
