In the hydrogenation of ethylene using a nickel catalyst, the initial concentration of ethylene is 2.00mol?L?1 and its rate cons

gavmur [86]

Answer:

The rate of reaction of a zero-order reaction is 0.0020 mol/L.

Explanation:

The rate expression of the zero order kinetic are :

$R=k[A]^o$

[A]= initial concentration of reactant

k = rate constant

R = rate of reaction

We have :

Rate constant of the reaction , k = 0.0020 mol/L s

$R=0.0020 mol/L s\times 1$

R = 0.0020 mol/L s

The rate of reaction of a zero-order reaction is 0.0020 mol/L.

2. ATO kg bouting ball would require what force to accelerate down an alleyway at a rate of ons?

Mars2501 [29]

Answer:

2. 30N

3. 5,000N

4. 15 kg

5. 2,800 kg

Explanation:

2. A 10 kg bowling ball would require what force to accelerate down an alleyway at a rate of 3m/s² ?

Notice that I completed the question with the garbled and missing values:

Data:

F = ?

m = 10 kg

a = 3m/s²

Physical principles:

Newton's second law: $F=m\times a$

Solution:

Substitute and compute

$F=10kg\times 3m/s^2=30N$

3. Salty has a car that accelerates at 5 m/s². If the car has a mass of 1000 kg, how much force does the car produce?

Notice that I arranged the typos.

Data:

F = ?

m = ?

a = ?

Physical principles:

Newton's second law: $F=m\times a$

Solution:

Substitute and compute

$F=1,000kg\times5m/s^2=5,000N$

4. What is the mass of a falling rock if it produces a force of 147 N?

Data:

F = 147N

m = ?

a = falling rock

Physical principles:

neglecting air resistance ⇒ a = g: gravitational acceleration: 9.8m/s²

Newton's second law: $F=m\times a$

Solution:

Clear m from Newton's second law

$m=\dfrac{F}{a}$

Substitute with F = 147 N and a = g = 9.8m/s², and compute

$m=\dfrac{147N}{9.8m/s^2}=15Kg$

5. What is the mass of a truck if it produces a force of 14,000 N while accelerating at a rate of 5 m/s²?

Data:

F= 14,000N

m = ?

a = 5m/s²

Physical principles:

Second Newton's law: $F=m\times a$

Solution:

Clear m from Newton's second law

$m=\dfrac{F}{a}$

Substitute with F = 14,000 N and a = 5m/s², and compute

$m=\dfrac{14,000N}{5m/s^2}=2,800kg$

Under which conditions is lactic-acid fermentation most likely to occur?

sattari [20]

Answer:

D. a very fast run

Explanation:

Fermentation :

The second step of anaerobic respiration is fermentation. It involve the fermentation of pyruvate into lactic acid or alcohol depending upon the organism in which it is taking place. There is no ATP produced, however carbon dioxide is released in this step.

Anaerobic respiration in plants:

Anaerobic respiration in plants produced ethanol which if accumulate then cause the harmful effect in plants. It is also occur in some microorganisms such as yeast.

C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂

Anaerobic respiration in animals:

Anaerobic respiration in animals pyruvate converted into lactic acid and it is not as harmful as ethanol in plant if accumulate. It is produced during exercise because oxygen is not supplied to muscles. It can produce the cramps which can be cured with massage.

C₆H₁₂O₆ → 2C₃H₆O₃
