What is the order of reaction?

We add together the individual orders of the reactants to get the reaction's overall order.

We have the following when the reaction has zero order in A, half order in B, and second order in C:

Order as a whole: 0 + 1/2 + 2 = 2 1/2 or 2.5

As a result, the reaction's overall order is 2.5.

During strenuous exercise, lactic acid builds up in muscle tissues. In a 1.00 M aqueous solution, 2.94% of lactic acid is ionized. What is the value of Ka for lactic acid?

Answers

The value of Ka for lactic acid is approximately 0.0303. To find the value of Ka for lactic acid, we can use the ionization percentage and the initial concentration of the acid.

Given that 2.94% of lactic acid is ionized in a 1.00 M solution, we can calculate the concentration of the ionized form ([tex]CH_{3}CH(OH)COO-[/tex]) by multiplying the ionization percentage by the initial concentration of the acid: [[tex]CH_{3}CH(OH)COO-[/tex]] = 2.94% × 1.00 M = 0.0294 M

Since lactic acid ([tex]CH_{3}CH(OH)COO-[/tex]) is a monoprotic acid, the concentration of the undissociated form is equal to the initial concentration minus the concentration of the ionized form: [[tex]CH_{3}CH(OH)COOH[/tex]] = 1.00 M - 0.0294 M = 0.9706 M

The equilibrium expression for the ionization of lactic acid can be written as: Ka = [[tex]CH_{3}CH(OH)COO-[/tex]] / [[tex]CH_{3}CH(OH)COOH[/tex]]

Substituting the values, we get: Ka = 0.0294 M / 0.9706 M = 0.0303

Therefore, the value of Ka for lactic acid is approximately 0.0303.

For the reaction

how many moles of SO3 can be produced from 6.0 g O2 and excess S?
Group of answer choices
none of these
0.28 mol SO3
4.0 mol SO3
0.25 mol SO3
0.13 mol SO3

Answers

To determine the number of moles of SO3 produced, we need to use the stoichiometry of the balanced equation.

The balanced equation tells us that 3 moles of O2 react with 2 moles of S to produce 2 moles of SO3. Therefore, the molar ratio between O2 and SO3 is 3:2.

To find the moles of SO3 produced from 6.0 g of O2, we need to convert the mass of O2 to moles using its molar mass. The molar mass of O2 is approximately 32 g/mol.

Moles of O2 = mass of O2 / molar mass of O2

Moles of O2 = 6.0 g / 32 g/mol

Moles of O2 = 0.1875 mol

Using the molar ratio, we can calculate the moles of SO3 produced:

Moles of SO3 = (0.1875 mol O2) x (2 mol SO3 / 3 mol O2)

Moles of SO3 = 0.125 mol

Therefore, the correct answer is 0.13 mol SO3.

The correct phrase that describes the effect of adding a catalyst to a chemical reaction in order to increase the reaction rate is: (b) provides a different reaction pathway with a lower activation energy.

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. It achieves this by providing an alternative reaction pathway with a lower activation energy, making it easier for the reactant molecules to reach the transition state and proceed to form the products.

The catalyst itself is not permanently altered or consumed in the reaction and can participate in multiple reaction cycles, thereby increasing the overall reaction rate.

Overall, the presence of a catalyst alters the reaction kinetics by providing a different reaction pathway with a lower activation energy, resulting in an increased reaction rate.

Enthalpy of

CH4(g) + 2NO2(g) -> N2(g) + CO2(g) + 2H2O(l)

Answers

Answer:

-177.9 kJ.

Explanation:

Use Hess's law. Ca(s) + CO2(g) + 1/2O2(g) → CaCO3(s) ΔH = -812.8 kJ 2Ca(s) + O2(g) → 2CaO(s) ΔH = -1269.8 kJ We need to get rid of the Ca and O2 in the equations, so we need to change the equations so that they're on both sides so they "cancel" out, similar to a system of equations. I changed the second equation. Ca(s) + CO2(g) + 1/2O2(g) → CaCO3(s) ΔH = -812.8 kJ 2CaO(s) → 2Ca(s) + O2(g) ΔH = +1269.8 kJ The sign changes in the second equation above since the reaction changed direction. Next, we need to multiply the first equation by two in order to get the coefficients of the Ca and O2 to match those in the second equation. We also multiply the enthalpy of the first equation by 2. 2Ca(s) + 2CO2(g) + O2(g) → 2CaCO3(s) ΔH = -1625.6 kJ 2CaO(s) → 2Ca(s) + O2(g) ΔH = +1269.8 kJ Now we add the two equations. The O2 and 2Ca "cancel" since they're on opposite sides of the arrow. Think of it more mathematically. We add the two enthalpies and get 2CaO(s) + 2CO2(g) → 2CaCO3(s) and ΔH = -355.8 kJ. Finally divide by two to get the given equation: CaO(s) + CO2(g) → CaCO3(s) and ΔH = -177.9 kJ.

where V=Volume and T=Temperature.

The temperature must be in kelvin.

K=C°+273

T1=40+273=313K

T2=55+273=328K

How is enthalpy related to the spontaneity of a reaction?
A. AH=0 contributes to spontaneity.
B. AH<0 contributes to spontaneity.
C. AH> 0 contributes to spontaneity.
D. AH does not affect spontaneity.

Answers

Answer:

D

Explanation:

Gibb's free energy change(∆G) and Standard electrode potential of electrochemical (Ecell) determine the spontaneity of a reaction.

when ∆G > 0, the reaction is not spontaneous

∆G < 0, the reaction is spontaneous

∆G = 0, the reaction is in equilibrium

when Ecell > 0, the redox reaction is spontaneous

Ecell < 0, the redox reaction is not spontaneous

Ecell = 0, the redox reaction is in equilibrium.

ΔH < 0 contributes to spontaneity.

What is a spontaneous reaction?A spontaneous reaction is one that takes place naturally under a certain set of circumstances. The general entropy, or chaos, of the system increases in the presence of spontaneous reactions.

How can we determine if a reaction is spontaneous or not?

We can determine it by calculating Gibb's free energy.

How do we calculate Gibb's free energy?

It is calculated by the formula:

ΔG = ΔH - TΔS

ΔG is the change in Gibb's free energy,ΔH is the change in the enthalpyΔS is the change in entropy.

How does ΔG tells if a reaction is spontaneous or not?If ∆G > 0, the reaction is not a spontaneous reaction∆G < 0, the reaction is a spontaneous reaction∆G = 0, the reaction is in equilibrium

How does ΔH contribute to the spontaneity of the reaction?For a reaction to be a spontaneous reaction, ∆G < 0.Consider a reaction, ΔG will be calculated as ΔH - TΔSIf ∆H < 0 then the ΔH - TΔS will be a lesser value ( more negative) than it would have been when ∆H = 0 or ∆H > 0.Therefore  ∆H < 0 contributes to spontaneity.

A buffer solution is prepared by mixing 250 mL of 1.00 M nitrous acid with 50 mL of 1.00 M sodium hydroxide. Is the resulting solution a buffer solution? Yes or No? What is the pH of the resulting solution? The pKa of nitrous acid is 3.35.
Suppose an additional 0.05 moles of sodium hydroxide are added to our buffer solution. What is the change in pH due to the addition of the 0.05 moles of sodium hydroxide?

Answers

Yes, the resulting solution is a buffer solution. The pH of the resulting solution is 3.35. The change in pH due to the addition of 0.05 moles of sodium hydroxide is a decrease of 0.70 units, resulting in a new pH of 2.65.

Yes, the resulting solution is a buffer solution. A buffer solution is a solution that can resist changes in pH when small amounts of acid or base are added to it. In this case, the nitrous acid and sodium hydroxide react to form their conjugate acid-base pair, which can help maintain the pH of the solution.

To determine the pH of the resulting solution, we need to compare the concentrations of the conjugate acid (nitrous acid, HNO₂) and conjugate base (nitrite ion, NO₂⁻) in the buffer solution.

The Henderson-Hasselbalch equation is used to calculate the pH of a buffer solution

pH = pKa + log([conjugate base]/[conjugate acid])

Volume of nitrous acid (conjugate acid) = 250 mL = 0.250 L

Concentration of nitrous acid (conjugate acid) = 1.00 M

Volume of sodium hydroxide (conjugate base) = 50 mL = 0.050 L

Concentration of sodium hydroxide (conjugate base) = 1.00 M

pKa of nitrous acid = 3.35

[conjugate base] = concentration of sodium hydroxide = 1.00 M

[conjugate acid] = concentration of nitrous acid = 1.00 M

pH = 3.35 + log(1.00/1.00) = 3.35

Therefore, the pH of the resulting solution is 3.35.

For the second part of the question, if an additional 0.05 moles of sodium hydroxide are added, we need to determine the change in pH.

Since the volume of the solution remains the same, the final concentration of sodium hydroxide ([conjugate base]) will be

[conjugate base] = (initial moles of sodium hydroxide + additional moles of sodium hydroxide) / total volume

[conjugate base] = (0.050 moles + 0.05 moles) / (0.250 L + 0.050 L) = 0.20 M

Using the Henderson-Hasselbalch equation with the updated concentration of the conjugate base, we can calculate the new pH

pH = pKa + log([conjugate base]/[conjugate acid])

pH = 3.35 + log(0.20/1.00) = 3.35 - 0.699 = 2.65

Answers

Adding HCl to the equilibrium BaSO4(s) ⇌ Ba²+(aq) + SO4²-(aq) will result in an increase in [Ba²+] and a decrease in [SO4²-]. The mass of the solid BaSO4 will also decrease.

When HCl is added, it dissociates into H+ and Cl- ions. The H+ ions react with the SO4²- ions from the dissociation of BaSO4, forming HSO4- ions and shifting the equilibrium to the right. As a result, more Ba²+ ions are released into the solution, leading to an increase in [Ba²+]. On the other hand, the decrease in [SO4²-] occurs because some of the SO4²- ions combine with H+ ions to form HSO4-. Since the equilibrium is being driven towards the products, the concentration of Ba²+ increases, [SO4²-] decreases, and the mass of the solid BaSO4 decreases.

Le Wood, Inc. Le Wood, Inc. makes furniture sets. During April, the purchasing agent bought 25,600 pounds of lumber at $1.94 per pound. During the month, 21,400 pounds of lumber were used to produce 600 furniture sets. Each set requires a standard quantity of 35 pounds at a standard cost of $1.90 per pound. The company applies fixed overhead at a rate of $3 per direct labor hour. Each furniture produced is expected to take 30 direct labor hours. Paper Products expected production in the current year to be 750 sets but 600 units were actually produced. Actual direct labor hours were 19,000 and actual fixed overhead costs were $62,000. REQUIRED 1. Find the direct material price variance (based on the quantity PURCHASED) for April. 2. Find the direct material quantity variance (based on quantity USED) for April. Assume the price elasticity of demand is unit-elastic. If price changes from $21 to $19, then the quantity demand must change from Ca. 416 to 464 units. b. 180 to 210 units. Cc. 210 to 180 units. Od. 464 to 416 units. on a side note, . . . you can hire people to navigate the process of buying a plane ticket, but why can't you hire someone to navigate the airport?"
