The pH of the solution of aniline is; pH = 4.64

<h3>pH of aniline solution</h3>

According to the question;

We are required to determine the hydrogen ion concentration, pH of the given aniline solution.

Since, the given Kb is kb = 4. 3 × 10⁻¹⁰.

Hence, it follows that;

Ka = 10-¹⁴/4. 3 × 10⁻¹⁰.

Ka = 2.3 × 10⁻⁵.

On this note, the pH of aniline solution is;

pH = -log {2.3 × 10⁻⁵}

pH = 4.64.

Ultimately, the pH of the aniline solution given is; 4.64

So what score do I need to go to Duke University

Alex73 [517]

The 25th percentile New SAT score is 1450, and the 75th percentile SAT score is 1570. In other words, a 1450 places you below average, while a 1570 will move you up to above average. There's no absolute SAT requirement at Duke, but they really want to see at least a 1450 to have a chance at being considered.

A high school track coach has just purchased a new stopwatch that has an uncertainty of s. runners on the team regularly complet

Alexeev081 [22]

A high school track coach has just purchased a new stopwatch. The stopwatch manual states that the stopwatch has an uncertainty of ±0.05 s . Runners on the track coach’s team regularly clock 100-m sprints of 11.49 s to 15.01 s . At the school’s last track meet, the first-place sprinter came in at 12.04 s and the second-place sprinter came in at 12.07 s .

No, the new stop watch will not be effective in timing the sprint team. The reason for the same is that the uncertainty in the stopwatch is too small to effectively differentiate between the sprint times.

If sprinters were timed with the new stopwatch, first sprinter's time would have been between = 12.04 - 0.05 and 12.04 + 0.05

= 11.99 and 12.09

or between the interval [11.99 , 12.09]

while the second sprinter's time would have been between

= 12.07 - 0.05 =and 12.07 + 0.05

= 12.02 and 12.12

or between the interval [12.0.2 , 12.12]

Hence, there is an overlap between the worst time of the first sprinter, that is, 11.99 and the best time of the second sprinter, that is, 12.02

Refer to Figure 4.7.1 above. Which of the expressions in the figure is the Lagrangian

Arturiano [62]

Using the image attached. The option that shows the marginal rate of substitution is option b.

<h3>What is marginal rate of substitution?</h3>

The marginal rate of substitution (MRS) is known to be the number of a good that a consumer is said to be willing to take in when compared to another good, only if the new good is said to be equally satisfying.

The marginal rate of substitution (MRS) is also described as the rate in which a specific units of an item is said to be replaced by another only if by giving the same amount of satisfaction to its consumer.

Hence, The MRS concept tells about the association between the taking in of two goods or resources if consumers are said to make rational decisions.

Hence, the option that satisfy the above is option B. Therefore, Using the image attached. The option that shows the marginal rate of substitution is option b.
