calculate δg∘rxnδgrxn∘ and e∘cellecell∘ for a redox reaction with nnn = 3 that has an equilibrium constant of kkk = 24 (at 25 ∘c∘c).

Answers

Answer 1

To calculate δg∘rxn and e∘cell for a redox reaction with n = 3 and k = 24, we need to use the following equations:

ΔG°rxn = -RTlnK
E°cell = (RT/nF)lnK

The given equilibrium constant, k = 24, represents the ratio of the concentration of products to reactants at equilibrium. Using the equation ΔG°rxn = -RTlnK, where R is the gas constant (8.314 J/mol•K), T is the temperature in Kelvin (25 + 273 = 298 K), and ln represents the natural logarithm, we can calculate the standard Gibbs free energy change for the reaction:

ΔG°rxn = -RTlnK
ΔG°rxn = -(8.314 J/mol•K)(298 K)ln(24)
ΔG°rxn = -4.86 kJ/mol

The negative value of ΔG°rxn indicates that the reaction is spontaneous (i.e., exergonic) under standard conditions.

To calculate the standard cell potential, E°cell, we use the equation:

E°cell = (RT/nF)lnK

Where F is Faraday's constant (96,485 C/mol). Substituting the values, we get:

E°cell = (8.314 J/mol•K)(298 K)/(3 × 96,485 C/mol)ln(24)
E°cell = 0.222 V

The positive value of E°cell indicates that the reaction is spontaneous in the forward direction (i.e., reduction of the oxidizing agent).

The presence of no subscript for an element in a chemical formula means that there is/are?

Answers

Answer:

only one atom of that element

Explanation:

Example:

   H2 O    has two hydrogenatoms and ONE Oxygen atom

The presence of no subscript for an element in a chemical formula means that there is a single atom of that element in the compound.

In a chemical formula, subscripts are used to indicate the number of atoms of each element present in a compound. When an element has no subscript, it means that there is only one atom of that element in the compound.

For example, in the chemical formula H₂O, the subscript 2 indicates that there are two hydrogen atoms present. On the other hand, the absence of a subscript for oxygen means that there is only one oxygen atom in the compound.

Thus, when there is no subscript for an element in a chemical formula, it signifies that there is a single atom of that element in the compound.

A student determines the mass of a 100 mL beaker filled with 50 mL of water to be 154.34 grams. After a tablet reacts with the water, the mass including the dissolved tablet is 157.26 grams. 438 grams tablet was left in the beaker after the reaction.

What is Stoichiometry ?

Stoichiometry helps us use the balanced chemical equation to measure quantitative relationships and it is to calculate the amounts of products and reactants that are given in a reaction.

What is Balanced Chemical Equation ?

The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.

Now we have to write the balanced chemical equation

NaHCO₃ + H₂O → NaOH + H₂CO₃

Mass = 157.26 - 154.32

         = 2.92

Volume = 100 + 50 ml

             = 150 ml

Mass of tablet = 2.92 × 150

                        = 438 grams

A technologist is creating a solution that contains 25.5 grams of NaOH that is dissolved in 1 L of laboratory grade water. What is the molarity of the solution that the technologist created

Answers

Answer:

0.638 M NaOH

Explanation:

To find the molarity of the solution, you need to (1) convert grams NaOH to moles NaOH (via the molar mass of NaOH) and then (2) calculate the molarity (via the molarity formula). It is important to arrange the conversions/ratios in a way that allows for the cancellation of units (the desired unit should be in the numerator).

(Step 1)

Molar Mass (NaOH): 22.990 g/mol + 15.998 g/mol + 1.008 g/mol

Molar Mass (NaOH): 39.996 g/mol

25.5 grams NaOH                 1 mole
-----------------------------  x  ----------------------------  =  0.638 moles NaOH
                                           39.996 grams

(Step 2)

Molarity = moles / volume (L)

Molarity = 0.638 moles / 1 L

Molarity = 0.638 M

A sample of gas has a temperature of 25 oc and a volume of 122 ml. if the volume is decreased to 50 ml, what is the new temperature?

Answers

Answer:

Explanation:

If all other variables are held constant, you can find the new temperature using the Charles' Law equation. The equation looks like this:

V₁ / T₁ = V₂ / T₂

In this equation, "V₁" and "T₁" represent the initial volume and temperature. "V₂" and "T₂" represent the final volume and temperature. You can find the new temperature by plugging the given values into the equation and simplifying.

V₁ = 122 mL                     V₂ = 50 mL

T₁ = 25 °C                        T₂ = ? °C

V₁ / T₁ = V₂ / T₂                                         <----- Charles' Law equation

122 mL / 25 °C = 50 mL / T₂                    <----- Insert values

4.88 = 50 mL / T₂                                     <----- Divide 25 from 122

4.88 x T₂ = 50 mL                                    <----- Multiply both sides by T₂

T2= 32 degrees

Answers

The rate of reaction at 150 degrees is 1.878.

What is the activation energy?

We have the formula as;

ln(k2/k1) = Ea/R (1/T1 - 1/T2)

ln(2( 0.0110)/0.0110) = 45.5  * 10^3/8.314(1/294 - 1/T2)

0.693 = 5473(1/294 - 1/T2)

0.693/ 5473 = (1/294 - 1/T2)

1.27 * 10^-4 = 1/294

1/T2 = 1/294  - 1.27 * 10^-4

1/T2 = 340 * 10^-4 - 1.27 * 10^-4

T2 = 30 degrees

Again;

ln(k2/0.0110) =  45.5  * 10^3/8.314(1/303 - 1/423)

ln(k2/0.0110) = 5473(3.3 * 10^3 - 2.36  * 10^3)

ln(k2/0.0110) = 5.14

k2/0.0110 = e^5.14

k2 = 0.0110 * e^5.14

k2 = 1.878

The temperature that the reaction will go twice as fast is 30 degrees while the rate construction at 150 degrees is 1.878.

A weather balloon calibrated at 0.00 °c to have a volume of 12.0 l has what volume at -22.8 °c assuming pressure is held constant?

Answers

Considering the Charles's law, the volume at 22.8 °C is 10.9978 L.

Charles's law

Charles's law establishes the relationship between the temperature and the volume of a gas when the pressure is constant.

Charles's law says that for a given sum of gas at constant pressure, as the temperature increases, the volume of the gas increases, and as the temperature decreases, the volume of the gas decreases. That is, the volume is directly proportional to the temperature of the gas.

Mathematically, Charles' law is a law that says that when the amount of gas and pressure remain constant, the ratio between volume and temperature will always have the same value:

[tex]\frac{V}{T} =k[/tex]

Considering an initial state 1 and a final state 2, it is fulfilled:

[tex]\frac{V1}{T1} =\frac{V2}{T2}[/tex]

Volume at -22.8 °C

In this case, you know that:

V1= 12 LT1= 0 °C= 273 KV2= ?T2= -22.8 °C= 250.2 K

Replacing in Charles's law:

[tex]\frac{12 L}{273 K} =\frac{V2}{250.2 K}[/tex]

Solving:

V2= [tex]250.2 K x\frac{12 L}{273 K}[/tex]

V2= 10.9978 L

g from 30.0 g of glucose.

Answers

Taking into account the reaction stoichiometry, 15.33 grams ethanol could be obtained from 30 grams of glucose.

Reaction stoichiometry

In first place, the balanced reaction is:

C₆H₁₂O₆  → 2 C₂H₅OH + 2 CO₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

C₆H₁₂O₆: 1 mole  C₂H₅OH: 2 molesCO₂: 2 moles

The molar mass of the compounds is:

C₆H₁₂O₆: 180 g/moleC₂H₅OH: 46 g/moleCO₂: 44 g/mole

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

C₆H₁₂O₆: 1 mole ×180 g/mole= 180 gramsC₂H₅OH: 2 moles ×46 g/mole= 92 gramsCO₂: 2 moles ×44 g/mole= 88 grams

Mass of C₂H₅OH formed

The following rule of three can be applied: if by reaction stoichiometry 180 grams of glucose form 92 grams of ethanol, 30 grams of glucose form how much mass of ethanol?

[tex]mass of ethanol=\frac{30 grams of glucosex 92 grams of ethanol}{180 grams of glucose}[/tex]

mass of ethanol= 15.33 grams

Then, 15.33 grams ethanol could be obtained from 30 grams of glucose.

If the prefix hydro were used to name a ternary acid, what problem would this create when naming chloric acid

Answers

Hydrochloric acid is a different kind of acid than chloric acid.

Ternary Acids (Oxy-acids) Ternary acids are also referred to as “Oxy-acids. Include hydrogen and oxygen and yet another (normally) nonmetallic detail. Those acids comprise each hydrogen and oxygen but their names make no reference to either hydrogen or oxygen.

A ternary acid is an acid that has the elements hydrogen and oxygen together with every other element, frequently a nonmetal. Or, they comprise hydrogen in addition to a polyatomic ion. An -ate complicated ion is named an -ic acid. as an example, HClO3(aq) consists of the chlorate ion and is known as chloric acid.

A binary acid is an acidic compound that always has hydrogen boned to every other chemical element, most of the time a nonmetal. Ternary acids are acidic compounds that comprise hydrogen and oxygen blended with some other detail. Binary acid has one style of a chemical element (hydrogen bonded to a nonmetal) .

During the procedure, several wases with cold methanol were done. why was it important to use cold methanol? (In nitration of methyl benzoate)

Answers

The use of cold methanol is important because it is used to recrystallize or solidify the product.

Since, ice bath is also used in nitration of methyl benzoate because in this reaction the concentrated acid like sulfuric acid is used with water and it is very exothermic.

The formation pure solid from the impure solid compound by mixing with hot solvent and form saturated solution. Now, this solution as cools and pure crystal grows when solubility of the compound decreases. This whole process is called re-crystallization.
