Are sorbents good for the environment?

Natural Inorganic Sorbents

Second, sorbents that sink should not be used as they could be harmful to the environment. Sinking is a problem with many sorbents, such as untreated peat moss, most inorganic sorbents, and many wood products.

Its major result is to clean out some surface contaminants, which makes it simpler for oil to absorb. On the other hand, pyrolysis, a high-temperature thermal treatment, causes the sorbent to carbonise. In turn, this greatly improves the oil sorption capacity and oil to water selectivity.

When recovering adsorbent materials that cause secondary contamination, lighter, less viscous oil is lost through the pores more readily than heavier, more viscous oils. Application is simple because sorbents can be applied automatically or manually to spills using blowers or fans.

The best sorbents for recovering oil are typically synthetic ones. In some circumstances, a weight ratio of 40:1 for oil to sorbent can be reached, as opposed to 10:1 for organic compounds and only 2:1 for inorganic materials.

A substance used to absorb or adsorb liquids or gases is known as a sorbent. Examples comprise: a substance that works via adsorption and is comparable to molecular sieve material (attracting molecules to its surface). It has strong thermal conductivity and a big interior surface area.

Thus, On the other hand, pyrolysis, a high-temperature thermal treatment, causes the sorbent to carbonise.

The conjugate base of an acid does not always carry a negative charge. To understand this, let us first define the terms 'acid' and 'conjugate base'.An acid is a substance that releases H+ ions when dissolved in water.

An example of an acid is hydrochloric acid (HCl) which releases H+ ions and chloride ions (Cl-) when dissolved in water. HCl + H2O → H3O+ + Cl-.A conjugate base is the substance that is formed when an acid loses a proton (H+ ion). It can be formed from any acid, whether it is weak or strong. The conjugate base of an acid is the species that remains after an acid has donated a proton to another species. In the case of HCl, Cl- is the conjugate base, and it carries a negative charge because it has gained an electron and has a greater number of electrons than protons.Conversely, the conjugate base of a weak acid may not carry a negative charge. For example, the conjugate base of acetic acid (CH3COOH) is acetate ion (CH3COO-) which does not carry a negative charge. Acetate ion has a greater number of electrons than protons, but its net charge is zero. Thus, the conjugate base of an acid does not always carry a negative charge.

water at the surface of the ocean can become water vapor and move into the atmosphere with little added energy from the sun through the process called evaporation. The water droplets that form are what we call clouds

Answer:

Over 96% of total global water is in the ocean, so let's start there. Energy from the sun causes water on the surface to evaporate into water vapor – a gas. This invisible vapor rises into the atmosphere, where the air is colder, and condenses into clouds.

A copper electrode is immersed in the solution that is 1 M in the ammonia and 1.00 M  in tetrammine copper(ii).  the concentration of the Cu²⁺ in the solution is 3.3 × 10¹¹ M.

given that :

concentration of ammonia = 1 M

concentration of the tetramine copper = 1 M

cell potential = 0.057 V

temperature = 298 K

the reaction

at cathode :

Cu²⁺  +  2e⁻  ---->  Cu      E° cathode = 0.337 V

at anode :

2H⁺  +  2e⁻  --->  H₂          E° anode = 0.00 V

electrode potential =  E° cathode -    E° anode

                                 = 0.337 - 0.00

                                 = 0.0337 V

Nernst equation :

E cell =  E° cell - (0.0591 / n ) log Q

0.055 V = 0.337 V - ( o.0591 / 2 ) log Q

log Q = 0.282 / 0.029

Q = 2.95 × 10⁻¹⁰

concentration of Cu²⁺ =  1 / Q

                                     = 1 / 2.95 × 10⁻¹⁰

                                     = 3.3 × 10¹¹ M

The enthalpy change (ΔH) for the physical change of Br2 from the gas phase to the gas phase (Br2(g) → Br2(g)) is zero. The entropy change (ΔS) for this physical change is also zero.

In a physical change, the chemical substance remains the same, and there is no breaking or forming of chemical bonds. In the case of Br2 going from the gas phase to the gas phase, there is no change in the chemical identity or composition of the substance.

The enthalpy change (ΔH) measures the heat energy transfer during a reaction or process. Since there is no change in the chemical bonds or composition of Br2 in this physical change, there is no transfer of heat energy, and thus ΔH is zero.

The entropy change (ΔS) quantifies the degree of disorder or randomness in a system. In this physical change, the arrangement and distribution of Br2 molecules remain unchanged, leading to no change in entropy. Therefore, ΔS is also zero.

Answer: 6 mol Li

Explanation:

The first step is to balance the equation.

2Li+Cl₂⇒2LiCl

We would need our conversions to find the amount of moles of Li needed to produces 6 mol LiCl.

\(6molLiCl*\frac{2molLi}{2molLiCl} =6molLi\)

ANSWER

The number of moles of the gas is 2.2 moles

EXPLANATION

Given thanks

The volume of the gas is 48.4L

To find the number of moles, follow the steps below

Recall, that 1 mole is equivalent to 22.4L/mol

Let x represents the number of moles of the gas

Hence, the number of moles of the gas is 2.2moles

Titration is the process of determining the amount of a substance in a solution by measuring the volume of a solution with a known concentration that is required to react with it. The answer to the given question is option d) 5.25.

In the titration of a weak base with a strong acid, the pH at the half-equivalence point can be calculated as follows: At the half-equivalence point, we have equal moles of the weak base and the strong acid. As a result, we get a solution that contains the weak base, its conjugate acid, and water. In the solution, there is an equilibrium between the weak base and its conjugate acid. This equilibrium has an acid dissociation constant, Ka. It's given by:

Ka = [H+][A–]/[HA]

The pKa is calculated by taking the negative logarithm of Ka:

pKa = -log(Ka)

At the half-equivalence point, [HA] = [A–] and the expression for pKa becomes:

pKa = -log([H+])

Therefore, the pH at the half-equivalence point is:

pH = 1/2 (pKb + pKa)

Given that pKb = 7.95 for the weak base, we can calculate the pKa:

pKw = 14 (at 25°C)

pKw = pKa + pKb

14 = pKa + 7.95

pKa = 6.05

Therefore, the pH at the half-equivalence point is:

pH = 1/2 (7.95 + 6.05)

pH = 1/2 (14)

pH = 7

At the half-equivalence point, the pH of the solution is equal to 7. Therefore, option d) 5.25 is incorrect.

Explanation:

The image represent in malleable property of metal.

The image possibly represents the photoelectric effect of a metal, which is when it emits electrons after being exposed to electromagnetic radiation. Metals are also characterized by physical properties such as conductivity, malleability, metallic luster, and metallic bonding.

Based on your question, the image possibly represents the photoelectric effect, a key property of metals. This phenomenon occurs when a metal surface exposed to electromagnetic waves of a certain frequency absorbs radiation and emits electrons. These emitted electrons are called photoelectrons. Metals can also exhibit free electron model behavior, where electrons freely roam within the metal structure.

Metals possess unique physical properties like conductivity, malleability, and metallic luster. Malleability refers to the metal's ability to deform without breaking, while conductivity refers to the metal's ability to transfer heat or electricity. A metallic luster gives metals their characteristic shiny appearance.

Finally, metals are also known for their metallic bonding—a unique force that holds together the atoms within a metallic solid. Metallic bonding gives rise to many useful and varied bulk properties of metals.
