Its a Beta Decay.

It is characterized by an Increase in the atomic Number of the of the product and No Change in the Mass Number of number of the product.

The given reaction has ΔG value  -12207KJ. Therefore, the given reaction is a spontaneous reaction as value of ΔG is negative.

A spontaneous process refers to anything that happens by itself, without external energy input. A ball is going to roll down an incline, water will flow downhill, ice will melt into water, radioactive elements will decay, and iron will rust, for instance. It is impossible for a reaction to not be spontaneous if it is exothermic (H negative) and increases the entropy for the system (S positive). The system's overall heat capacity is measured in enthalpy. The system's unpredictability is gauged by entropy.

ΔG=ΔH-T×ΔS

ΔG=11-298×41

     = -12207KJ

Since ΔG is negative, reaction is spontaneous

The concentration of H3O+  of 0.25 M NH4 Cl is calculated as 1.13 × 10⁻⁵ M.

Hydronium ion concentration is found from pH by reverse of the mathematical operation that is employed to find pH.

NH4Cl + H2O → NH4+ + Cl- + H2O

NH4+ + H2O → H3O+ + NH3

Ka = [H3O+][NH3] / [NH4+]

[NH4+] = 0.25 M - x

At equilibrium, the concentration of NH3 will also be equal to x (since NH4+ and NH3 are in a 1:1 ratio). The concentration of H3O+ will also be equal to x (since NH4+ donates a proton to form H3O+).

5.6 × 10-10 = (x)(x) / (0.25 - x)

x = 1.13 × 10⁻⁵ M

Therefore, the concentration of H3O+ is 1.13 × 10⁻⁵ M.

6.02 x \(10^{20\) formula units of MgCl₂ is equal to 0.1 moles of MgCl₂.

To convert formula units of MgCl₂ to moles of MgCl₂, we need to use Avogadro's number, which relates the number of formula units to the number of moles.

Avogadro's number (NA) is approximately 6.022 x 10^23 formula units per mole.

Given that we have 6.02 x 10^20 formula units of MgCl₂, we can set up a conversion factor to convert to moles:

(6.02 x 10^20 formula units MgCl₂) * (1 mol MgCl₂ / (6.022 x 10^23 formula units MgCl₂))

The formula units of MgCl₂ cancel out, and we are left with moles of MgCl₂:

(6.02 x 10^20) * (1 mol / 6.022 x 10^23) = 0.1 mol

Therefore, 6.02 x 10^20 formula units of MgCl₂ is equal to 0.1 moles of MgCl₂.

It's important to note that this conversion assumes that each formula unit of MgCl₂ represents one mole of MgCl₂. This is based on the stoichiometry of the compound, where there is one mole of MgCl₂ for every one formula unit.

Additionally, this conversion is valid for any substance, not just MgCl₂, as long as you know the value of Avogadro's number and the number of formula units or particles you have.

Answer:

Positively charged:  Lysine, Histidine

Negatively charged:  Asparagine, Phenylalanine, Glutamatic acid, Alanine, Glycine, Leucine, Aspartic acid

Explanation:

The charge of an amino acid in solution is determined by its isoelectric point, pI, which is the characteristic pH in which the net electric charge of the amino acid is zero. In solutions of pH below the isoelectric point, the amino acid has a net positive charge whereas in solutions with pH above isoelectric point, the net charge on the amino acid is negative.

In a buffer solution of pH 6.5, the following charges are present in the amino acids given:

Positively charged:  Lysine (pI = 9.74), Histidine (pI = 7.59)

Negatively charged:  Asparagine (pI = 5.07), Phenylalanine (pI = 5.48), Glutamatic acid (pI = 3.22), Alanine (pI = 6.01), Glycine (pI = 5.97), Leucine (pI = 5.98), Aspartic acid (pI = 2.77)

The decomposition of aspirin (acetylsalicylic acid,\(C_{9} H_{8} O_{4}\)) can occur through the hydrolysis reaction, resulting in the formation of acetic acid (\(CH_{3} COOH\)) and salicylic acid (\(C_{7} H_{6}O_{3}\)).

The decomposition of aspirin (acetylsalicylic acid, \(C_{9} H_{8} O_{4}\)) can occur through the hydrolysis reaction, resulting in the formation of acetic acid (\(CH_{3} COOH\)) and salicylic acid (\(C_{7} H_{6}O_{3}\)). To determine the moles of each product formed, we need to consider the balanced chemical equation for the reaction:

\(C_{9} H_{8} O_{4} = > C_{7} H_{6}O_{3} +CH_{3} COOH\)

From the equation, we can see that for every 1 mole of aspirin, 1 mole of salicylic acid and 1 mole of acetic acid are produced.

Therefore, the moles of salicylic acid and acetic acid formed will be equal to the number of moles of aspirin that decomposes. If we know the amount of aspirin in moles, we can directly calculate the moles of each product based on stoichiometry.

Answer:

the enthalpy of the second intermediate equation is halved and has its sign changed.

Explanation:

Let us take a look at the first and second intermediate reactions as well as the overall reaction equation for the process under review;

First reaction;

Ca (s) + CO₂ (g) + ½O₂ (g) → CaCO₃ (s) ΔH₁ = -812.8 kJ

Second reaction;

2Ca (s) + O₂ (g) → 2CaO (s) ΔH₂ = -1269 kJ

Hence the overall equation is now;

CaO (s) + CO₂ (g) → CaCO₃ (s) ΔH = ?

According to the Hess law of constant heat summation, the enthalpy of the overall reaction is supposed to be obtained as a sum of the enthalpy of both reactions but this will not give the enthalpy of the overall reaction in this case. The enthalpy of the overall reaction is rather obtained by halving the enthalpy of the second intermediate reaction and reversing its sign before taking the sum as shown below;
