The limiting reagent is the reactant that you don't have a lot of, it will be completely used up in the reaction

Answer:

4.767 grams of KCl are produced from 2.50 g of K and excess Cl2

Explanation:

The balanced equation is

2 K+ Cl2 --->2 KCI

Here the limiting agent is K. Hence, the amount of KCl will be calculated as per the mass of 2.50 gram of K

Mass of one atom/mole of potassium is 39.098 grams

Number of moles is 2.5 grams = [tex]\frac{2.5}{39.098} = 0.064[/tex]

So, 2 moles of K produces 2 moles of KCL

0.064 moles of K will produces 0.064 moles of KCl

Mass of one molecule of KCl is 74.5513 g/mol

Mass of 0.064 moles of KCl is 4.767 grams

The mass of KCl produced is 4.77g

From the question, we are to determine the mass of KCl produced

From the given balanced chemical equation,

2K + Cl₂ → 2KCl

This means,

2 moles of potassium reacts with 1 mole of Chlorine to produce 2 moles of potassium chloride

First, we will determine the number of moles of potassium (K) present.

Using the formula,

[tex]Number\ of \ moles = \frac{Mass }{Atomic\ mass}[/tex]

Atomic mass of K = 39.098 g/mol

Then,

Number of moles of K present = [tex]\frac{2.50}{39.098}[/tex]

Number of moles of K present = 0.06394 mole

Now,

If 2 moles of K reacts to produce 2 moles of KCl

Then,

0.06394 moles of K reacts to produce 0.06394 moles of KCl

Thus, the number of moles of KCl produced is 0.06394.

Now, for the mass of KCl produced

From the formula,

Mass = Number of moles × Molar mass

Molar mass of KCl = 74.5513 g/mol

Then,

Mass of KCl produced = 0.06394 × 74.5513

Mass of KCl produced = 4.7668 g

Mass of KCl produced = 4.77 g

Hence, the mass of KCl produced is 4.77g

Answer:

a) the final temperature of the air is 500° R

b) the amount of specific entropy produced is 0.0758 Btu/lb-°R  

Explanation:

Given the data in the question;

Air at 500° R = [tex]T_i[/tex]

Using first law of thermodynamic;

δQ = dU + W

now, since the vessel is insulated, the transfer is zero, work done also is zero since there is also no external work done.

δQ = dU + W

0 = dU + 0

dU = 0

[tex]u_f[/tex] - [tex]u_i[/tex] = 0

[tex]u_f[/tex] = [tex]u_i[/tex]

hence, change in internal energy is 0

Now, since the ideal internal energy is a function of temperature, the temperature will also remain the same;

[tex]T_f = T_i[/tex]

F = 500° R

Therefore, the final temperature of the air is 500° R

b)

given that; initial volume is one-third of the total volume

V₁ = [tex]\frac{1}{3}[/tex]V₂

3V₁ = V₂

3 = V₂/V₁

Now, we take the value of gas constant R from air property table;  gas constant R = 0.069 Btu/lb-R  

so we calculate the entropy change;

Δs = [tex]c_v[/tex]In( [tex]\frac{T_2}{T_1}[/tex] ) + R.In( [tex]\frac{V_2}{V_1}[/tex] )

we substitute

Δs = [tex]c_v[/tex]In( [tex]\frac{500}{500}[/tex] ) + 0.069 × In( 3 )

Δs = 0 + [0.069 × In( 3 )]

Δs = 0 + [0.069 × 1.0986]

Δs = 0.0758 Btu/lb-°R  

Therefore, the amount of specific entropy produced is 0.0758 Btu/lb-°R  

Insulated vessels separate the environment of the outer and the inner system. The final temperature is 500 degrees R and 0.0758 Btu/lb- degree R is the entropy.

The temperature is the measure of the hot or the coldness of the system.  The first law of the thermodynamics is used to measure the final temperature of the system:

[tex]\rm \Delta Q = \rm \Delta U + W[/tex]

The work done will be zero as the system is insulated and no external work is being done.

[tex]\begin{aligned} \rm 0 &= \rm \Delta U + 0\\\\\rm U_{f} - U_{i} &= 0\\\\\rm U_{f} &= \rm U_{i} \end{aligned}[/tex]

Hence, the change in the internal energy is zero. Thus, the final temperature will remain the same,

[tex]\rm T_{f} = \rm T_{i} = 500 ^{\circ} \rm R[/tex]

Now, as we know, the initial volume is one-third of the total volume then,

[tex]\begin{aligned} \rm V_{1} &= \rm \dfrac{1}{3} V_{2}\\\\\rm 3V_{1}&= \rm V_{2}\\\\3 &= \rm \dfrac{V_{1}}{V_{2}}\end{aligned}[/tex]

The change in entropy is calculated as:

[tex]\begin{aligned} \rm \Delta S &= \rm C_{v} ln ( \dfrac{T_{2}}{T_{1}}) + R \times ln ( \dfrac{V_{2}}{V_{1}}) \\\\&= 0 + [0.069 \times \rm ln( 3 )]\\\\& = 0.0758 \;\rm Btu/lb-^{\circ}R \end{aligned}[/tex]

Therefore, the entropy produced is 0.0758 Btu/lb- degree R.

Answer:

esterification reaction in which an alcohol and a carboxylic acid react to form an ester

Explanation:

Esterification involves the reaction of  an alcohol and a carboxylic acid  to form an ester. This is an analogue of amidation which involves the reaction of a carboxylic acid with an amine to form an amide.

The relationship between the two reactions is that in both cases, the carbonyl (CO) group of the carboxylic acid is maintained and then bonded to a new moiety in the product. Water is formed in both reactions.

Hence, for esterification;

RCOOH + ROH ------> RCOOR + H2O

For amidation;

RCOOH + RNH2 -------> RCONHR + H2O

We're given the [OH⁻] as 8.34 × 10⁻¹² M. Using the formula pOH = -log[OH⁻], the pOH of this solution would be -log(8.34 × 10⁻¹²) ≈ 11.08.

The pOH is, for lack of a better term, the "opposite" of pH: A pOH of 7 is neutral; a pOH less than 7 is basic; and a pOH greater than 7 is acidic.

This follows from the relation, pH + pOH = 14. In this case, with a pOH of 11.08, our pH would be 14 - 11.08 = 2.92, which is acidic (pH < 7).

Thus, the correct answer choice is B.

Answer:

0.20 g/L

Explanation:

Step 1: Calculate the molar mass of the gas (M)

At T = 350 °C = 623 K and P = 1 atm (we will assume this data), the density (ρ) of the gas is 0.087 g/L. We can calculate the molar mass of the gas using the following expression.

ρ = P × M/R × T

M = ρ × R × T/P

M = 0.087 g/L × (0.0821 atm.L/mol.K) × 623 K/1 atm = 4.5 g/mol

Step 2: Calculate the density of the gas at STP

At standard temperature (T = 273.15 K) and standard pressure (P = 1 atm), the density of the gas is:

ρ = P × M/R × T

ρ = 1 atm × 4.5 g/mol /(0.0821 atm.L/mol.K) × 273.15 K = 0.20 g/L

Answer:

0.24 M

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

H₂SO₄ + 2NaOH —> Na₂SO₄ + 2H₂O

From the balanced equation,

The mole ratio of the acid, H₂SO₄ (nₐ) = 1

The mole ratio of the base, NaOH (n₆) = 2

Finally, we shall determine the molarity of the acid. This can be obtained as follow:

Volume of acid, H₂SO₄ (Vₐ) = 17.4 mL

Molarity of base, NaOH (M₆) = 0.20 M

Volume of base, NaOH (V₆) = 41.51 mL

Molarity of acid, H₂SO₄ (Mₐ) =?

MₐVₐ / M₆V₆ = nₐ / n₆

Mₐ × 17.4 / 0.2 × 41.51 = 1 / 2

Mₐ × 17.4 / 8.302 = 1 / 2

Cross multiply

Mₐ × 17.4 × 2 = 8.302

Mₐ × 34.8 = 8.302

Divide both side by 34.8

Mₐ = 8.302 / 34.8

Mₐ = 0.24 M

Therefore, the molarity of the acid is 0.24 M

Answer:

they are molecules with normal bonds rather than partial bonds and can occasionally be isolated.

Explanation:

In chemistry, reaction intermediates are species that are formed from reactants and are subsequently being transformed into products as the reaction progresses. In other words,  reaction intermediates are species that do not appear in a balanced reaction equation but occur somewhere along the reaction mechanism of a non-elementary reaction. They are usually short lived species that possess a high amount of energy. They may or may not be isolated.

They are often molecular species with normal bonds unlike activated complexes that are sometimes hypervalent species.

a.

Initial moles of (CH₃CH₂)₃N = (0.1000 mol/L) × (20.00/1000 L) = 0.002 mol

Moles of HCl added = (0.1000 mol/L) × (13.00/1000 L) = 0.0013 mol

Addition of 1 mole of HCl reacts with 1 mole of (CH₃CH₂)₃N to 1 mole of (CH₃CH₂)₃NH⁺.

After addition of 13.00 mL of HCl:

Moles of (CH₃CH₂)₃N left unreacted = (0.002 - 0.0013) mol = 0.0007 mol

Moles of (CH₃CH₂)₃NH⁺ produced = 0.0013 mol

Hence, [(CH₃CH₂)₃NH⁺]/[(CH₃CH₂)₃N] = 0.0013/0.0007 = 13/7

Consider the dissociation of (CH₃CH₂)₃N:

(CH₃CH₂)₃N(aq) + H₂O(l) ⇌ (CH₃CH₂)₃NH⁺(aq) + OH⁻(aq) …… Kb = 5.2 × 10⁻⁴

Henderson-Hasselbalch equation:

pOH = pKb + log([(CH₃CH₂)₃NH⁺]/[(CH₃CH₂)₃N])

pOH = -log(5.2 × 10⁻⁴) + log(13/7) = 3.55

pH = pKw - pOH = 14.00 - 3.55 = 10.45

b.

Initial moles of (CH₃CH₂)₃N = 0.002 mol

Moles of HCl added = (0.1000 mol/L) × (20.80/1000 L) = 0.00208 mol

HCl is in excess.

Moles of HCl left unreacted = (0.00208 - 0.002) mol = 0.00008 mol

Volume of the final solution = (20.00 + 20.80) mL = 40.8 mL = 0.0408 L

In the final solution:

[H₃O⁺] = [HCl] = (0.00008 mol) / (0.0408 L) = 0.00196

pH = -log[H₃O⁺] = -log(0.00196) = 2.71

====

c.

Initial moles of (CH₃CH₂)₃N = 0.002 mol

Moles of HCl added = (0.1000 mol/L) × (29.00/1000 L) = 0.0029 mol

HCl is in excess.

Moles of HCl left unreacted = (0.0029 - 0.002) mol = 0.0009 mol

Volume of the final solution = (20.00 + 29.00) mL = 49 mL = 0.049 L

In the final solution:

[H₃O⁺] = [HCl] = (0.0009 mol) / (0.049 L) = 0.0184

pH = -log[H₃O⁺] = -log(0.0184) = 1.74
