if you mixed succinate, fumarate, fad, and fadh2 together, all at 1 m concentrations and in the presence of the appropriate enzyme (succinate dehydrogenase), what would happen initially to the fumarate and fadh2?

1) The temperature of the egg at time t can be calculated using the equation T(t) = 18 + 80 * e^(-0.168t), where t is the time measured in minutes.

2) The realistic domain of the temperature function is t ≥ 0, meaning time cannot be negative.

3) A rough analysis of the temperature function shows an exponential decay curve starting at 98°C and approaching 18°C asymptotically. There is an intercept at t = 0, corresponding to the initial temperature of 98°C.

4) It takes approximately 18.17 minutes for the egg to cool to a temperature of 20°C.

1.

To solve for T(t), we can use the formula derived from Newton's Law of Cooling:

T(t) - Ts = (T0 - Ts) * e^(-kt)

Given the initial conditions:

T0 = 98°C (initial temperature of the egg)

Ts = 18°C (surrounding temperature)

T(5) = 38°C (temperature of the egg after 5 minutes)

We can substitute these values into the equation:

T(5) - 18 = (98 - 18) * e^(-5k)

20 = 80 * e^(-5k)

Dividing both sides by 80:

1/4 = e^(-5k)

Take the natural logarithm of both sides:

ln(1/4) = -5k

Solving for k:

k = -ln(1/4) / 5 ≈ 0.168

Now we have the value of k. We can substitute it back into the equation to get the temperature function:

T(t) - 18 = (98 - 18) * e^(-0.168t)

Simplifying further:

T(t) = 18 + 80 * e^(-0.168t)

2.

The realistic domain of the temperature function is t ≥ 0 since time cannot be negative.

3.

Analyzing the function:

The function is exponential decay, starting at 98°C and approaching 18°C asymptotically. There is an intercept at t = 0, where the temperature is 98°C. As time progresses, the temperature decreases and approaches 18°C. However, it never reaches exactly 18°C due to the exponential decay nature of the function.

4.

To find the time it takes for the egg to cool to a temperature of 20°C, we can substitute T(t) = 20 and solve for t:

20 = 18 + 80 * e^(-0.168t)

2 = 80 * e^(-0.168t)

Dividing both sides by 80:

1/40 = e^(-0.168t)

Taking the natural logarithm of both sides:

ln(1/40) = -0.168t

Solving for t:

t = -ln(1/40) / (-0.168) ≈ 18.17 minutes

Therefore, it takes approximately 18.17 minutes for the egg to cool to a temperature of 20°C.

Answer:

x = 1/2 y = 1

Step-by-step explanation:

Now form equation for y,

→ 6x - y = 2

→ y = 6x - 2

Then the value of x will be,

→ -4x + 3y = 1

→ -4x + 3(6x - 2) = 1

→ -4x + 18x - 6 = 1

→ 14x = 1 + 6

→ x = 7/14

→ [ x = 1/2 ]

Hence, the value of x is 1/2 (or) 0.5.

Now the value of y will be,

→ y = 6x - 2

→ y = 6(1/2) - 2

→ y = 3 - 2

→ [ y = 1 ]

Hence, the value of y is 1.

Based on the mentioned informations and provided values, the number of unpaired electrons in [FeBr6]3− is found to be one.

To determine the number of unpaired electrons in [FeBr6]3−, we need to first determine the electronic configuration of Fe(III) ion.

Fe(III) ion has 26 electrons with the configuration 1s2 2s2 2p6 3s2 3p6 3d5 4s0. When it forms an octahedral coordination complex with six bromide ions, each Br atom donates one electron to form a coordinate covalent bond with Fe(III) ion.

This results in the hybridization of the d orbitals of Fe(III) ion to form six sp3d2 hybrid orbitals, which are arranged in an octahedral geometry.

According to the crystal field theory, the six ligands will cause the d orbitals to split into two sets of three: the lower energy t2g set (dxy, dxz, and dyz) and the higher energy eg set (dx2-y2 and dz2).

Since Fe(III) has five electrons in the d orbitals, the first five electrons will occupy the t2g orbitals, leaving one unpaired electron in the eg set. Therefore, the [FeBr6]3− complex has one unpaired electron.

Thus, the number of unpaired electrons in [FeBr6]3− is one.

Charles's Law helps us understand the relationship between temperature and volume of a gas when other factors, such as pressure and number of moles, remain constant. The empirical gas law that describes the relationship between the volume and temperature of a gas when the number of moles and pressure are constant is Charles's Law.  

This can be expressed mathematically as: V₁/T₁ = V₂/T₂
Where V₁ and V₂ represent the initial and final volumes of the gas, and T₁ and T₂ represent the initial and final temperatures of the gas, respectively. The relationship can also be stated as: V/T = constant

To find the volume of gaseous products formed in the given reaction, we have to balance the chemical equation and then use the balanced chemical equation to solve the question.

The balanced chemical equation of the given reaction is as follows:

CO (g) + H2O (l) → CO2 (g) + H2 (g)

Now, we need to determine the mole ratios of reactants and products:

1 mole of CO reacts with 1 mole of H2O to produce 1 mole of CO2 and 1 mole of H2.

As given, we have 119 liters of CO, we need to calculate the amount of H2O required to react with 119 liters of CO:

1 mole of CO occupies 22.4 L at STP.

Therefore, 119 L of CO contains 119/22.4 = 5.31 moles of CO.

From the balanced chemical equation, we can see that 1 mole of CO reacts with 1 mole of H2O.

Therefore, 5.31 moles of CO will react with 5.31 moles of H2O.

So, the volume of H2O required to react with 119 L of CO can be calculated as follows:

5.31 moles of H2O occupy 5.31 × 18 L = 95.58 L

Now, we have the volume of H2O required to react with 119 L of CO.

We know that, at the same temperature and pressure, the volume of the gaseous product is directly proportional to the number of moles of the gaseous product.

So, the volume of gaseous products formed in the given reaction can be calculated as follows:

1 mole of CO2 occupies 22.4 L at STP.

Therefore, 5.31 moles of CO2 will occupy 5.31 × 22.4 L = 119.2 L

1 mole of H2 occupies 22.4 L at STP.

Therefore, 5.31 moles of H2 will occupy 5.31 × 22.4 L = 119.2 L

Therefore, the total volume of gaseous products formed in the given reaction is 119.2 L. Answer: 119.2

The Barometric Pressure must be subtracted from each pressure measurement in order to determine the vapor pressure of the liquid.

The force per unit area that an atmospheric column (i.e., the entire body of air above the given location) exerts is known as barometric pressure. A mercury barometer (thus the often used synonym barometric pressure) may be used to measure atmospheric pressure because it displays the height of a mercury column that precisely balances the weight of the atmosphere above the barometer.

An aneroid barometer, which uses one or more hollow, partially evacuated, corrugated metal discs supported against collapse by an inside or outside spring, can also be used to measure atmospheric pressure. The change in the disk's shape with changing atmospheric pressure can be recorded using a pen arm and a clock-driven revolving drum.

Atmospheric pressure is measured in a variety of ways, including millimetres (or inches) of mercury, pounds per square inch (psi), dynes per square centimetre (dyne/cm2), millibars (mb), standard atmospheres, and kilopascals. By definition, a standard atmosphere is equal to one atmosphere at sea level, which is equivalent to 101.325 kilopascals, 760 mm (29.92 inches) of mercury, 14.70 pounds per square inch, 1,013.25 millibars, and 1,013.25 103 dynes per square centimetre.

Explanation:

So, the formula mass of aluminum chloride is 26.98154+3(35.453)=133.34054 g/mol.

This means that 42.3 grams of aluminum chloride are 42.3/133.34054=0.31723285356426 moles.

From the equation, we know that for every 3 moles of bromine consumed, 2 moles of aluminum chloride are consumed.

This means that (0.31723285356426)(3/2)=0.47584928034639 moles of bromine are needed.

So, the formula mass of a bromine molecule is 2(79.904)=159.808 g/mol, and thus the answer is (159.808)(0.47584928034639), which is about 76.1 g

R = 0.0821 L atm K-1 mol-1

a = 4.17 atm L2 mol-2

b = 0.0371 L mol-1

Ideal gas equation

PV = nRT

P = nRT / V

P = 3.21 x 0.0821 x 50.0 / 5.22

P = 2.52 atm

Van der Waals equation

P = RT / V - b - a / V²

P = 0.0821 x 50.0 / 5.22 - 0.0371 - 4.17 / ( 5.22 )²

P = 0.317 - 0.153

To calculate the standard Gibbs free energy change (ΔG°rxn) for the given reaction, we use the equation:

ΔG°rxn = ΔH°rxn - TΔS°rxn

where ΔH°rxn is the standard enthalpy change and ΔS°rxn is the standard entropy change.

Given:

ΔH°rxn = -133.9 kJ/mol + 50.6 kJ/mol - 285.8 kJ/mol = -368.7 kJ/mol

ΔS°rxn = 266.9 J/mol + 121.2 J/mol + 191.6 J/mol - 70.0 J/mol = 509.7 J/mol

Its pressure will be 0.54 atm at 100 K.

Explanation:

Gay-Lussac's law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions with the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.

Gay-Lussac's law can be expressed mathematically as the quotient between pressure and temperature equal to a constant:

\(\frac{P}{T} =k\)

Studying two different states, an initial state 1 and a final state 2, it is satisfied:

\(\frac{P1}{T1} =\frac{P2}{T2}\)

In this case:

Replacing:

\(\frac{1.75 atm}{323 K} =\frac{P2}{100 K}\)

Solving:

\(P2= 100 k*\frac{1.75 atm}{323 K}\)

P2= 0.54 atm

Its pressure will be 0.54 atm at 100 K.
