Explanation:

it turns out that an object increases as the square of it's speed.

Answer:

Explanation:

In all physical processes taking place in closed systems, the amount of change in kinetic energy is equal to the amount of change in potential energy. If the kinetic energy increases, the potential energy decreases, and vice-versa. this equation reveals that the kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four. so therfore stays the same as the object so it would speed up as well.

The 1H NMR spectrum of the compound Br CH CH Br would be expected to show 2 signals.

In 1H NMR spectroscopy, each type of proton in a molecule gives rise to a unique signal in the spectrum, with the number of signals reflecting the number of different types of protons in the molecule. In this case, the molecule contains two distinct types of protons: the protons in the CH groups and the protons in the CHBr groups.

Each of these two types of protons is expected to give rise to a separate signal in the 1H NMR spectrum, with the position of each signal reflecting the chemical environment of the protons. For example, the CH protons are likely to exhibit a different chemical shift than the CHBr protons, which would result in two different signals in the spectrum.

It is worth noting that the presence of bromine atoms can sometimes cause broadening of the signals from the CHBr protons, making it difficult to accurately determine their chemical environment. However, the use of proper 1H NMR techniques, such as high-resolution spectroscopy, can help to resolve these signals and provide a clear picture of the proton environment in the molecule.

To calculate the value of AG' at 298 K, we need to use the equation: AG' = AH' - TAS'.                                                                            

First, we need to convert the values given to kJ/molcan. AH298 = -92.2 kJ/molrani x (1 mol/2 molcan) = -46.1 kJ/molcan.
AS298 = -198.8 J/(molznK) x (1 kJ/1000 J) x (1 mol/2 molcan) = -0.0994 kJ/(molcanK). Therefore, AG' = -46.1 kJ/molcan - (298 K x (-0.0994 kJ/(molcanK))) = -46.1 kJ/molcan + 29.64 kJ/molcan = -16.46 kJ/molcan. Thus, the value of AG' at 298 K is -16.46 kJ/molcan.
The reaction of N2(g) and H2(g) to form NH3(g) can be analyzed using the Gibbs free energy equation, which is ΔG = ΔH - TΔS. To maximize the yield of NH3(g), we need to calculate ΔG' at 298 K.
Therefore, the value of ΔG' at 298 K is -32.9 kJ/mol.

Answer: –1,267.2 kJ

Explanation: B on edge, thank me later ;-)

–1,267.2 kJ is the enthalpy of the given reaction. Therefore, the correct option is option A among all the given options.

Enthalpy is a thermodynamic system's internal energy total as well as the volume times pressure ratio. Enthalpy is a property or state function that resembles energy; it has the same dimensions as energy and is therefore measured in joules or ergs. The value of enthalpy is solely dependent on the temperature, pressure, as well as composition of the system, not on its history.

The shift in the internal energy equals equivalent to the heat transmitted to, much less than the jobs completed by, the system, in accordance with the principle of energy conservation. The enthalpy change is precisely equal to the heat transmitted to the system if the sole work performed is a change in volume at constant pressure.

ΔH = ΔH for product - ΔH for reactant

     = 3,572.1 kJ –1,267.2 kJ

    = –1,267.2 kJ

Explanation:

Decomposition reaction, also known as analysis or dissociation, is a type of chemical reaction in which a compound breaks down into simpler substances or elements. In this reaction, a single reactant undergoes a chemical change and produces two or more products.

The decomposition reaction can be represented by the general equation:

AB → A + B

Where AB is the reactant, and A and B are the products. The reactant AB is usually a compound, and it breaks down into its constituent elements or simpler compounds.

There are different types of decomposition reactions, including:

Thermal decomposition: It occurs when a compound is heated, resulting in its decomposition into simpler substances. For example, the thermal decomposition of calcium carbonate (CaCO3) produces calcium oxide (CaO) and carbon dioxide (CO2):

CaCO3 → CaO + CO2

Electrolytic decomposition: It takes place when an electric current is passed through an electrolyte, causing it to break down into its component ions. For instance, the electrolysis of water (H2O) leads to the decomposition into hydrogen gas (H2) and oxygen gas (O2):

2H2O → 2H2 + O2

Photochemical decomposition: It occurs when a compound undergoes decomposition due to exposure to light energy. Chlorine gas (Cl2) can decompose into chlorine atoms (Cl) under the influence of light:

Cl2 → 2Cl

These are just a few examples of decomposition reactions. They are important in various chemical processes and are used in industries, laboratory experiments, and natural phenomena. By understanding and controlling decomposition reactions, scientists can gain insights into the behavior of different compounds and develop practical applications in fields such as chemistry, materials science, and environmental science.

The value of Y in the formula when 2.8g of silicon react with 3.2g of oxygen, is 2

The numbers in the formula of a compound determine the ratio of moles of each element in the compound.

Given:

2.8g of silicon

3.2g of oxygen

[relative atomic mass of silicon is 28 and of oxygen is 16]

For silicon, n = 2.8 ÷ 28 = 0.1    (n= moles)

For oxygen, n = 3.2 ÷ 016 = 0.2

For the mole ratio, we divide each value of the moles by the smallest number of moles calculated which is 0.1 moles.

For Silicon = 0.1/0.1 = 1

For Oxygen = 0.2/0.1 = 2

Taking the mole ratio as their subscripts.

The ratio of Si:O is 1:2

SiO\(_{2}\) is the formula of silicon dioxide.

The value of y in the formula SiO\(_{Y}\) is 2 when 2.8g of silicon react with 3.2g of oxygen.

I hope it's helpful!!

To answer this question, we can use the relationship between enthalpy and equilibrium constant:

ΔG = -RTlnK

where ΔG is the change in Gibbs free energy, R is the gas constant, T is the temperature in Kelvin, and K is the equilibrium constant.

We can relate ΔH to ΔG using the equation:

ΔG = ΔH - TΔS

where ΔS is the change in entropy. At equilibrium, ΔG = 0, so we can rearrange the equation to solve for the equilibrium constant:

ΔH = -TΔS

ΔS = -ΔH/T

ΔG = ΔH - TΔS = ΔH - ΔH = 0

Therefore:

ΔH = -RTlnK

-lnK = ΔH/(RT)

lnK = -ΔH/(RT)

K = e^(-ΔH/(RT))

Now we can plug in the values given in the question:

ΔH = -24.8 kJ/mol
T = 298 K
R = 8.314 J/(mol·K)

K = e^(-(-24.8 kJ/mol)/(8.314 J/(mol·K) × 298 K))

K = 3.1 × 10^3

Therefore, the equilibrium constant for the reaction is 3.1 × 10^3.

"The species that would be expected to have the highest concentration in the 0.1 M solution of H₂S is HS⁻ (option c)."

In a 0.1 M solution of hydrogen sulfide (H₂S), the species that would be expected to have the highest concentration depends on the dissociation equilibrium of H₂S. Hydrogen sulfide is a weak diprotic acid, meaning it can donate two protons (H⁺) in separate steps. The dissociation of H₂S can be represented as follows:

H₂S ⇌ H⁺ + HS⁻ (Equation 1)

HS⁻ ⇌ H⁺ + S²⁻ (Equation 2)

To determine which species will have the highest concentration, we need to examine the acid dissociation constants (Ka) for these equilibria.

From Equation 1, the equilibrium constant expression can be written as:

Ka1 = [H⁺][HS⁻] / [H₂S]

From Equation 2, the equilibrium constant expression can be written as:

Ka₂ = [H⁺][S²⁻] / [HS⁻]

In a dilute solution like 0.1 M, we assume that the dissociation of H₂S is incomplete, so we can make the approximation [H₂S] ≈ 0.1 M. Therefore, the concentration of H₂S is approximately constant.

Now, let's consider the pKa values for these equilibria. The pKa1 value for H₂S is approximately 7, and the pKa₂ value for HS⁻ is approximately 14.

Since pKa₁ is lower than pKa₂, it means that the equilibrium represented by Equation 1 is more favorable than the one represented by Equation 2. Thus, at equilibrium, the concentration of HS- will be higher than that of S2-.

Therefore, the species that would be expected to have the highest concentration in the 0.1 M solution of H₂S is HS⁻ (option c).
