The concentration of the diluted HCl solution is 0.363 M, rounded to 3 decimal places.

When a stock solution is diluted, the number of moles of the solute (in this case, HCl) remains constant. We can use the following equation to find the concentration of the diluted solution:

M1V1 = M2V2

where M1 is the initial concentration of the stock solution, V1 is the volume of the stock solution used, M2 is the final concentration of the diluted solution, and V2 is the final volume of the diluted solution.Substituting the given values, we get:

(3.31 M) × (17.5 mL) = M2 × (159 mL)

Solving for M2, we get:

M2 = (3.31 M × 17.5 mL) / 159 mL = 0.363 M.

a. There are 0.1596 moles of NaCl in 0.3 L of NaCl stock solution.

b. There are 0.1596 moles of NaCl in 2.1 L of NaCl dilute solution.

c. The concentration of NaCl in the final solution is 0.076 M.

Molarity is said to be the number of moles of solute per liter of solution. For example, when salt is dissolved in water, the salt becomes the solute and the water becomes the solution. Since, one mole of sodium chloride weighs 58.44 grams and dissolving 58.44 grams of NaCl in 1 liter of water makes a 1 molar solution, abbreviated as 1M.

c. Let's calculate the concentration of NaCl in the final solution:

M₁V₁ = M₂V₂

M₁ = Initial concentration of NaCl (0.532 M)

V₁ = Initial volume of NaCl (0.3 L)

M₂ = Final concentration of NaCl

V₂ = Initial volume of NaCl (2.0 L)

0.532 × 0.3 = M₂ × 2.1

M₂ = (0.532 × 0.3)/2.1

M₂ = 0.076 M

a. To calculate number of moles in 0.3 L of NaCl stock solution.

Molarity = Mole of solute/Volume of solution

0.532 = Mole of NaCl/0.3

Mole of NaCl = 0.532×0.3

Mole of NaCl = 0.1596 mol

b. To calculate number of moles in 2.1 L of NaCl solution.

0.076 = Mole of NaCl/2.1

Mole of NaCl = 0.076×2.1

Answer: The soil biota benefits soil productivity and contributes to the sustainable function of all ecosystems. The cycling of nutrients is a critical function that is essential to life on earth. Earthworms (EWs) are a major component of soil fauna communities in most ecosystems and comprise a large proportion of macrofauna biomass. Their activity is beneficial because it can enhance soil nutrient cycling through the rapid incorporation of detritus into mineral soils. In addition to this mixing effect, mucus production associated with water excretion in earthworm guts also enhances the activity of other beneficial soil microorganisms. This is followed by the production of organic matter. So, in the short term, a more significant effect is the concentration of large quantities of nutrients (N, P, K, and Ca) that are easily assimilable by plants in fresh cast depositions. In addition, earthworms seem to accelerate the mineralization as well as the turnover of soil organic matter. Earthworms are known also to increase nitrogen mineralization, through direct and indirect effects on the microbial community. The increased transfer of organic C and N into soil aggregates indicates the potential for earthworms to facilitate soil organic matter stabilization and accumulation in agricultural systems, and that their influence depends greatly on differences in land management practices. This paper summarises information on published data on the described subjects.

Explanation: Protection of the soil habitat is the first step towards sustainable management of its biological properties that determine long-term quality and productivity. It is generally accepted that soil biota benefits soil productivity but very little is known about the organisms that live in the soil and the functioning of the soil ecosystem. The role of earthworms (EWs) in soil fertility is known since 1881, when Darwin (1809–1882) published his last scientific book entitled “The formation of vegetable mould through the action of worms with observations on their habits.’’ Since then, several studies have been undertaken to highlight the soil organisms contribution to the sustainable function of all ecosystems [1]. Soil macrofauna, such as EWs, modify the soil and litter environment indirectly by the accumulation of their biogenic structures (casts, pellets, galleries, etc.) (Table 1). The cycling of nutrients is a critical ecosystem function that is essential to life on earth. Studies in the recent years have shown increasing interest in the development of productive farming systems with a high efficiency of internal resource use and thus lower input requirement and cost [2, 3]. At present, there is increasing evidence that soil macroinvertebrates play a key role in SOM transformations and nutrient dynamics at different spatial and temporal scales through perturbation and the production of biogenic structures for the improvement of soil fertility and land productivity [4, 5]. EWs are a major component of soil fauna communities in most natural ecosystems of the humid tropics and comprise a large proportion of macrofauna biomass [6]. In cultivated tropical soils, where organic matter is frequently related to fertility and productivity, the communities of invertebrates—especially EWs—could play an important role in (SOM) dynamics by the regulation of the mineralization and humification processes [7–9]. The effects of EWs on soil biological processes and fertility level differ in ecological categories [12]. Anecic species build permanent burrows into the deep mineral layers of the soil; they drag organic matter from the soil surface into their burrows for food. Endogeic species live exclusively and build extensive nonpermanent burrows in the upper mineral layer of soil, mainly ingested mineral soil matter, and are known as “ecological engineers,’’ or “ecosystem engineers.’’ They produce physical structures through which they can modify the availability or accessibility of a resource for other organisms [13]. Epigeic species live on the soil surface, form no permanent burrows, and mainly ingest litter and humus, as well as on decaying organic matter, and do not mix organic and inorganic matter [14]. In the majority of habitats and ecosystems (Table 2), it is usually a combination of these ecological categories which together or individually are responsible for maintaining the fertility of soils [15–17]. EWs influence the supply of nutrients through their tissues but largely through their burrowing activities; they produce aggregates and pores (i.e., biostructures) in the

X₃Z₄ (g) → 3X (g) + 4Z(g)The given reaction is:rate constant of 0.687 1/hr: X₃Z₄ (g)→ 3X (g) + 4Z(g).Moles of X₃Z₄  = 3.00,Amount of time = 234 minutes rate constant = 0.687 1/hrTo find: Amount of Z produced.

We can use the integrated rate law of the first order reaction to calculate the concentration and amount of the reactant and product.First order reaction can be written ask =

-d[X₃Z₄ ] / dt = k [X₃Z₄]

In the above equation,k = rate constant, [X₃Z₄] = concentration of reactant.Since the initial concentration of X₃Z₄ is not given, we cannot use the above equation directly. Therefore, we use the integrated rate equation for the first-order reaction as follows,

ln([X₃Z₄] / [X₃Z₄]0) = - kt... Equation (1)

where [X₃Z₄]0 is the initial concentration of the reactant.From the balanced chemical equation, 1 mole of X₃Z₄ yields 4 moles of Z. So,

234 min = 234/60 = 3.9 hr

Moles of X₃Z₄= 3.00moles of Z = 3.00 × 4 = 12.00

As per the given data,k = 0.687 1/hrtime t = 3.9 hr,x = [X₃Z₄] / [X₃Z₄],where [X₃Z₄] = 3.00 - x

Therefore,ln([X₃Z₄] / [X₃Z₄]0) = ln(3.00 - x / 3.00) = - 0.687 × 3.9= - 2.68× 3.9= - 10.452

Then,3.00 - x / 3.00 = e - 10.452x = 3.00 (1 - e - 10.452)

Therefore,x = 0.275The amount of Z produced will be 4 times this value as 1 mol of X₃Z₄ produces 4 mol of Z.Thus, the amount of Z produced is,12.00 × 0.275 = 3.3 moles

Therefore, the amount of Z that can be produced is 3.3 moles.

The nitric acid (HNO₃) in the reaction represented by the equation below is:

HNO₃(l) + H₂O(l) ⟶ 3 H₃O⁺(aq) + NO₃⁻(aq)

Nitric acid (HNO₃) is acting as a strong acid in this reaction.

When nitric acid (HNO₃) is dissolved in water (H₂O), it undergoes a process called dissociation or ionization. In this process, the acid molecules break apart into ions. Nitric acid is known as a monoprotic acid, meaning it can donate one proton (H⁺).

Nitric acid (HNO₃) is initially in its molecular form in the liquid state.

When it is added to water (H₂O), the acid molecules interact with water molecules.

The proton (H⁺) in nitric acid is highly acidic and easily transfers to a water molecule, forming a hydronium ion (H₃O⁺).

HNO₃(l) + H₂O(l) ⟶ H₃O⁺(aq) + NO₃⁻(aq)

Since nitric acid is a strong acid, it undergoes complete dissociation in water. This means that nearly all of the nitric acid molecules ionize to form hydronium ions (H₃O⁺) and nitrate ions (NO₃⁻).

The equation shows that for every molecule of HNO₃ that dissociates, three hydronium ions (H₃O⁺) and one nitrate ion (NO₃⁻) are formed.

The presence of three hydronium ions (H₃O⁺) on the product side indicates that the acid is completely ionized in water. Strong acids have a high degree of ionization and readily donate their protons to the solvent (in this case, water). They dissociate almost entirely, resulting in the formation of a large number of ions in solution.

Based on the complete ionization and the formation of multiple hydronium ions (H₃O⁺), we classify nitric acid (HNO₃) as a strong acid in this reaction.

An electron with a negative energy is attached to the nucleus by the attraction between its opposing charges. The closer it is to the nucleus, the more closely connected it is. The farther an electron is from the nucleus, the greater its energy. The correct option is B.

The electron's energy grows as it goes away from the nucleus and gets less and less negative. When the electron is not subject to the nucleus's attracting Coulomb attraction, it has zero potential energy and only kinetic energy, which is always positive. The electron has greater energy the further it travels.

On the other hand, the nucleus's weak forces of attraction hold electrons that are moving away from it.
