Answer: The answer is B. The pressure inside the tires increased.

Explanation:

The relationship between the pressure, volume, and temperature of a gas is described by the ideal gas law, which is usually written as:

\($$PV = nRT$$\)

where:

- \(\(P\)\) is the pressure,

- \(\(V\)\) is the volume,

- \(\(n\)\) is the number of moles of gas,

- \(\(R\)\) is the ideal gas constant, and

- \(\(T\)\) is the temperature (in Kelvin).

In this case, the volume \(\(V\)\) and the number of moles \(\(n\)\) of air in the tires stay the same. The temperature \(\(T\)\) is increasing. Therefore, for the equation to remain balanced, the pressure \(\(P\)\) must also increase.

So, the answer is B. The pressure inside the tires increased.

The formation of ionic bonds between elements from Group I (alkali metals) and Group VII (halogens) occurs through a transfer of electrons. Alkali metals have one valence electron in their outermost shell, while halogens require one more electron to complete their outermost shell and achieve a stable electron configuration.

Let's take the example of sodium (Na) from Group I and chlorine (Cl) from Group VII to illustrate the formation of an ionic bond. Sodium has one valence electron, while chlorine requires one electron to complete its outer shell.

In a dot-and-cross diagram, sodium is represented by the symbol Na, with a dot next to it representing its single valence electron. Chlorine is represented by the symbol Cl, with seven dots around it representing its seven valence electrons.

To form an ionic bond, sodium will transfer its single valence electron to chlorine. This results in sodium losing one electron to become a positively charged sodium ion (Na+), as it now has one less electron than protons. Chlorine, on the other hand, gains the electron from sodium, resulting in a negatively charged chloride ion (Cl-), as it now has one more electron than protons.

In the dot-and-cross diagram, the electron transfer is represented by an arrow from sodium to chlorine, indicating the movement of the electron. The final configuration shows the sodium ion (Na+) with no dots around it, indicating the loss of its valence electron, and the chloride ion (Cl-) with eight dots around it, representing the complete octet in its outermost shell.

The resulting sodium ion and chloride ion are held together by the strong electrostatic attraction between the oppositely charged ions. This attraction forms an ionic bond, creating an ionic compound known as sodium chloride (NaCl), commonly known as table salt.

This process of electron transfer and formation of ionic bonds occurs between elements from Group I and Group VII, leading to the creation of stable compounds with full outer shells for both elements.\(\huge{\mathcal{\colorbox{black}{\textcolor{lime}{\textsf{I hope this helps !}}}}}\)

Answer:

5.45*10⁻⁴ moles of silane gas (SiH₄) are present in 8.68 mL  measured at 18°C and 1.50 atm.

Explanation:

An ideal gas is a theoretical gas that is considered to be composed of point particles that move randomly and do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.

An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:

P * V = n * R * T

In this case:

Replacing:

1.5 atm* 0.00868 L= n* 0.082\(\frac{atm*L}{mol*K}\) *291 K

Solving:

\(n=\frac{1.5 atm*0.00868 L}{0.082 \frac{atm*L}{mol*K}*291 K}\)

n= 5.45*10⁻⁴ moles

5.45*10⁻⁴ moles of silane gas (SiH₄) are present in 8.68 mL  measured at 18°C and 1.50 atm.

The rate law for the reaction between NO(g) and  \(H_2\) (g) to produce \(N_2\)(g) and \(H_2O\) (g) is given as rate =\(k[NO]^2[H2]\).

a. The order of the reaction with respect to NO is 2. This means that the rate of the reaction is directly proportional to the square of the concentration of NO.

b. The order of the reaction with respect to  \(H_2\)  is 1. This means that the rate of the reaction is directly proportional to the concentration of  \(H_2\) .

c. The overall order of the reaction is the sum of the individual orders, so in this case, the overall order is 2 + 1 = 3.

d. The units for the rate constant, k, can be determined by substituting the units of concentration and time into the rate law equation and solving for the units of k. In this case, the rate has units of concentration over time (e.g., mol/L s), and the concentrations of NO and \(H_2\) are in  \(H_2\) mol/L. Therefore, the units of k would be \((mol/L)^{-2+(-1)} s^{-1}\), which simplifies to \(mol^{-1} L s^{-1}\).

In summary, the order of the reaction with respect to NO is 2, the order with respect to  \(H_2\)  is 1, the overall order is 3, and the units for the rate constant, k, are \(mol^(-1) L s^(-1)\).

Answer: 140

Explanation:

Given the following :

Mass of metal = 18g = 0.018kg

Mass of water (calorimeter) = 21g = 0.021kg

Initial temperature of metal = 273 + 96 = 369k

Initial temperature of water = 273 + 24 = 297k

Final temperature inside calorimeter = 273 + 26 = 299k

Temperature change of metal = 299 - 369= -70k

Temperature change of water = 299 - 297 = 2k

H = mc ΔT

m = mass

c = specific heat capacity

ΔT = change in temperature

Heat lost by metal = heat gained by water

mc ΔT = mc ΔT

Specific heat capacity of water = 4200

18 * C * ( 299 - 369 ) = 21 * 4.2 * ( 299 - 297)

0.018 × C × -70 = 0.021 × 4.2 × 2

- 1.26 × C = 0.1764

C = 176.4/1.26

C = 140

At equivalence there is no more HA and no more NaOH, for this particular reaction. So that means we have a beaker of NaA and H2O. The H2O contributes 1 x 10-7 M hydrogen ion and hydroxide ion. But NaA is completely soluble because group 1 ion compounds are always soluble. So NaA breaks apart in water and it just so happens to be in water. So now NaA is broken up. The Na+ doesn't change the pH but the A- does change the pH. Remember that the A anion is from a weak acid. That means it will easily attract a hydrogen ion if one is available. What do you know? The A anion is in a beaker of H+ ions! So the A- will attract H+ and become HA. When this happens, it leaves OH-, creating a basic solution, as shown below.

The NaOH given to the student should weigh 46.3 grams.

The formula units can be calculated as moles multiplied by the Avogadro number.

Avogadro number is, 6.023 × 10^23.

The formula units are given to be 7.03 × 10^23.

Formula units = Avogadro Number × Number of moles

7.03 × 10^23 = 6.023 × 10^23 × Number of moles

Number of moles = (7.03 × 10^23)/(6.033 × 10^23)

Number of moles = 1.16

One mole of NaOH has the mass 39.99 grams.

1.16 moles of NaOH has mass = 1.16 × 39.99 grams.

= 46.38 grams.

The difference in solubility can be attributed to the difference in Ksp values. Since magnesium hydroxide has a significantly higher Ksp value compared to aluminum hydroxide, it is more soluble in water.

The solubility product constant (Ksp) is a measure of a compound's solubility in water. A lower Ksp value indicates lower solubility, while a higher Ksp value indicates greater solubility. In this case, aluminum hydroxide has a Ksp of 1.2 x 10^-33 at 25°C.

Comparing this to the Ksp of magnesium hydroxide, which has a Ksp of 5.61 x 10^-12 at 25°C, it is clear that magnesium hydroxide is more soluble than aluminum hydroxide.

Here, magnesium hydroxide (Mg(OH)2 has a significantly higher Ksp value compared to aluminum hydroxide Al(OH)3, and so is more soluble in water. This higher solubility of magnesium hydroxide means it is more likely to dissolve and dissociate into its ions when mixed with water, making it a more effective antacid. In conclusion, based on the Ksp values provided, magnesium hydroxide is more soluble than aluminum hydroxide at 25°C.

At 27°C and constant pressure, the volume of the gas in the balloon is approximately 240.0 mL.To solve this problem, we need to use the combined gas law, which relates the pressure, volume, and temperature of a gas:\((P_1V_1)/T_1 = (P_2V_2)/T_2\)

Where \(P_1\)and \(T_1\) are the initial pressure and temperature, \(V_1\)is the initial volume, \(P_2\) and \(T_2\) are the final pressure and temperature, and  \(V_2\) is the final volume we are trying to find.We are given the initial volume \(V_1\) = 120.0 mL, the initial temperature \(T_1\)= -123C, and the pressure is constant, so we can assume \(P_1 = P_2\). We need to convert the temperatures to Kelvin, so \(T_1\) = 150 K and \(T_2\)= 300 K.

Using the combined gas law, we can solve for \(V_2\):
\((P_1V_1)/T_1 = (P_2V_2)/T_2\)
\((P_1)(120.0 mL)/(150 K) = (P_2)(V_2)/(300 K)\)
Simplifying, we can cancel out the pressures and cross-multiply:
\(V_2\) = (120.0 mL)(300 K)/(150 K)
\(V_2\) = 240.0 mL
Therefore, the volume of the gas in the balloon at 27C is 240.0 mL.To answer your question, we'll use Charles's Law, which states that the volume of a gas is directly proportional to its temperature in Kelvin, as long as the pressure remains constant.Charles's Law formula: \(V_1/T_1 = V_2/T_2\)

Where:
\(V_1\) = initial volume = 120.0 mL
\(T_1\) = initial temperature = -123°C
\(V_2\)= final volume (what we want to find)
\(T_2\) = final temperature = 27°C

First, we need to convert the temperatures from Celsius to Kelvin:
\(T_1\)(K) = -123°C + 273.15 = 150.15 K
\(T_2\)(K) = 27°C + 273.15 = 300.15 K

Now, we can plug in the values into Charles's Law formula:
(120.0 mL / 150.15 K) = (\(V_2\) / 300.15 K)
To find \(V_2\), we'll rearrange the equation and multiply both sides by 300.15 K:
\(V_2\) = (120.0 mL / 150.15 K) × 300.15 K
\(V_2\)≈ 240.0 mL

The 0.600 mole gas sample has a capacity of approximately 12.9 L at 15 °C and 1.10 atm of pressure. The right answer is (a) 12.9 L.

To calculate the volume of a gas sample, we can use the ideal gas law, PV = nRT, where P is the pressure in atm, V is the volume in liters, n is the number of moles, R is the gas constant (0.0821 L·atm/mol·K), and T is the temperature in Kelvin.

First, we need to convert the temperature from Celsius to Kelvin by adding 273.15 to it.

T = 15°C + 273.15 = 288.15 K

Now, we can rearrange the ideal gas law to solve for V:

V = (nRT) / P

Substituting the given values, we get:

V = (0.600 mol x 0.0821 L·atm/mol·K x 288.15 K) / 1.10 atm

Simplifying this expression, we get:

V ≈ 12.9 L

Therefore, the approximate volume of the 0.600 mole gas sample at 15°C and a pressure of 1.10 atm is 12.9 L. The correct option is (a) 12.9 L.
