The correct designations for the signs of Δ.h, Δ.s, and Δ.g for this reaction are Δ.h < 0, Δ.s > 0, and Δ.g < 0.

The dissolution of ammonium nitrate in water is an exothermic process, meaning that it releases heat to the surroundings. Therefore, Δ.h is negative. The dissolution also increases the disorder of the system, or entropy, which is positive for Δ.s. Finally, Δ.g, the Gibbs free energy change, can be calculated using the equation

where T is the temperature in Kelvin. Since Δ.h is negative and Δ.s is positive, Δ.g will be negative at room temperature, indicating that the reaction is spontaneous.

To calculate Δ.h for the dissolution of ammonium nitrate, we can use the equation Δ.h = q/m, where q is the heat absorbed or released by the system, and m is the mass of the solute. In this case, the temperature change was 5.0°C, or 5.0 K, and the solution contained 80.0 g of ammonium nitrate. The heat released by the system can be calculated using the equation q = mcΔT, where c is the specific heat capacity of water (4.18 J/g°C). Therefore,

The negative sign indicates that heat was released by the system, as expected for an exothermic process. Dividing q by m gives us Δ.h:

Since Δ.h is negative and Δ.s is positive, we can conclude that Δ.g is negative and the reaction is spontaneous.

The required number of collection of coins of each kind are C(33 4).

Since there are no less than 30 coins of every sort of coin, there is plausible that we can pick each of the 30 of a similar kind.

So reiteration is permitted and request doesn't make any difference since every sort of coin is something very similar.

So we utilize the recipe C(k+n­1 k). There are four kinds of coin (k=4), and we pick 30 coins (n=30).

Then,

there are C(33 4) potential ways.

Madison figures out the average and range of chloride readings from wells close to the ocean. Other than a query, she has carried out an operation. The answer id option (d).

The standard deviation is a measure of variance from the mean that takes spread, dispersion, and dispersion into account. The standard deviation displays a "typical" divergence from the mean. It is a well-liked measure of variability since it retains the primary units of measurement from the data set.  A minor variation occurs when the numbers are close to the mean, while a high variation occurs when they are far from the mean.

The standard deviation describes the degree to which the results deviate from the mean. The average deviation, which depends on all values, is the most often used metric for measuring dispersion. Consequently, the standard deviation's value can be altered even by a slight change in one value.

The volume of the Illustrated cone used as an example is 51.3cm³.

Volume is a measurement of three-dimensional space that is occupied. It is frequently expressed numerically using SI-derived units, as well as different imperial or US-standard units. Volume and the definition of length are related.

A cone is a recognizable three-dimensional geometric shape with a flat and curved surface that is pointed upward. The formula for the volume of a cone is V=1/3hπr²

Let's say the radius is 7cm. The volume will be:

Answer:

x = 11

z = 86

Step-by-step explanation:

8x + 6 and 10x-16 are vertical angles

Vertical angles are pairs of angles that are opposite each other and have the same vertex, or point of intersection. They are formed when two lines intersect at a point, and are always congruent, or of equal measure.

To solve this equation, we need to isolate the variable x on one side of the equation. To do this, we can start by subtracting 6 from both sides of the equation:

8x + 6 - 6 = 10x - 16 - 6

8x = 10x - 22

Now we can subtract 8x from both sides of the equation:

8x - 8x = 10x - 22 - 8x

0 = 2x - 22

To solve for x, we can add 22 to both sides of the equation:

0 + 22 = 2x - 22 + 22

22 = 2x

Finally, we can divide both sides of the equation by 2 to find the value of x: 22 / 2 = 2x / 2

x = 11

Therefore, the solution to the equation is x = 11.

Now that we have x, z is a supplementary angle to 8x + 6 (or you could do 10x - 16)

Supplementary angles are pairs of angles that add up to 180 degrees. They are formed when two lines intersect at a point, and the angles formed at the intersection are supplementary.

First plug in x, 8x + 6 = 8(11) + 6 = 88 + 6 = 94

180 - 94 = z

z = 86

Answer:

the number which has no factors is known as prime number

Answer: numbers that have only 1 and itself as factors.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let's assume the initial number of men at the exhibition is 10x, and the initial number of women is 3x.

After 110 men left, the number of men remaining is 10x - 110.

The total number of people remaining is (10x - 110) + (3x) = 13x - 110.

According to the given information, the number of men remaining (10x - 110) is 5/12 of the total number of people remaining (13x - 110). We can write this as an equation:

10x - 110 = (5/12)(13x - 110)

To solve this equation, we can start by simplifying both sides:

10x - 110 = (65/12)x - (55/6)

To get rid of the fractions, we can multiply both sides of the equation by 12:

12(10x - 110) = 65x - 110(2)

120x - 1320 = 65x - 220

Next, we can bring the x terms to one side and the constant terms to the other side:

120x - 65x = 1320 - 220

55x = 1100

Dividing both sides by 55, we find:

x = 20

Now, we can substitute the value of x back into the initial expressions to find the number of men and women:

Number of men = 10x = 10(20) = 200

Number of women = 3x = 3(20) = 60

Therefore, there were 60 women at the exhibition

A 99% confidence interval for the average number of free throws in practice is; CI = (211.25, 238.75)

A confidence interval is defined as the mean of your estimate plus and minus the variation in that estimate. Thus, the formula for confidence interval is;

CI = x' ± z(s/√n)

where;

x' is sample mean

s is standard deviation

n is sample size

z is z-score at confidence level

Now, z-score at confidence level of 99% is; z = 2.576

We are given;

x' = 225

Sample size; n = 43

Standard deviation; s = 35

Thus;

CI = 225 ± 2.576(35/√43)

CI = 225 ± 13.75

CI = (225 - 13.75), (225 + 13.75)

CI = (211.25, 238.75)

Arithmetic expressions can be used as control expressions in programming languages when a control structure, such as an if statement or a loop, expects a condition to determine the flow of execution

Arithmetic expressions can be used as control expressions in certain programming languages or contexts where a control structure expects a conditional expression to determine the flow of execution.

Typically, control expressions are used in decision-making structures such as if statements, while loops, for loops, and switch statements.

In most programming languages, the control expression must evaluate to a boolean value (true or false) in order to determine the execution path. However, some languages allow arithmetic expressions to be used in control structures, considering a value of zero as false and any non-zero value as true.
