i hope this one helps, hehe.

Answer:

If the atoms are not identical, the electron distribution is electrons are closer to one atom than the other. This type of bond is called a(n) covalent bond.

Explanation:

The molar mass is an essential concept in chemistry that refers to the mass of one mole of a substance. It is expressed in grams per mole (g/mol) and is used in various calculations, such as determining the number of moles of a substance in a given mass or volume. The molar mass of Cl in grams is approximately 35.5 g/mol.

To determine the molar mass of Cl in grams, we first need to identify the element's atomic mass. Chlorine (Cl) has an atomic number of 17, which means that it has 17 protons and, in its neutral state, 17 electrons. The atomic mass of Cl is the sum of the number of protons and neutrons in the nucleus, and it is approximately 35.5 g/mol.

To convert this value to grams, we simply need to multiply the atomic mass by the molar mass constant, which is 1 g/mol. Therefore, the molar mass of Cl in grams is approximately 35.5 g/mol.

It is worth noting that the molar mass of a substance can be calculated by adding up the atomic masses of its constituent atoms. For example, if we wanted to calculate the molar mass of a compound that contains two Cl atoms and one O atom, we would add the atomic masses of Cl and O (35.5 g/mol + 16 g/mol) and multiply the result by two (since there are two Cl atoms), plus the atomic mass of O, which is 16 g/mol. This would give us the molar mass of the compound in grams per mole.

In conclusion, the molar mass of Cl in grams is approximately 35.5 g/mol. This value is important in various chemical calculations and is a fundamental concept in chemistry.

Answer:

Approximately \(3.6 \times 10^{-10}\; {\rm M}\), assuming that the solution is dilute and is at room temperature (such that \(K_\text{w} = 10^{-14}\).)

Explanation:

Look up the ion product constant of water:

\(K_{\text{w}} \approx 10^{-14}\).

In a dilute solution where water is the solvent, the product of \([{\rm {H_{3}O}^{+}}]\) and \([{\rm {OH}^{-}}]\) (concentration of \(\rm {H_{3}O}^{+}}\) ions and \({\rm {OH}^{-}}\) ions) is constantly equal to \(K_{\text{w}}\). (The unit of both \([{\rm {H_{3}O}^{+}}]\!\) and \([{\rm {OH}^{-}}]\!\) need to be \({\rm M}\).) In other words:

\([{\rm {H_{3}O}^{+}}]\, [{\rm {OH}^{-}}] = K_{\text{w}}\).

Rearrange this equation to find \([{\rm {OH}^{-}}]\) in terms of \(K_{\text{w}}\) and \([{\rm {H_{3}O}^{+}}]\):

\(\begin{aligned}[] [ {\rm OH^{-}} ] &= \frac{K_{\text{w}}}{[{\rm {H_{3}O}^{+}}]} \\ &= \frac{10^{-14}}{2.8 \times 10^{-5}} \\ &\approx 3.6 \times 10^{-10}\end{aligned}\).

Answer: The gravitational force Increase as the objects get closer.

Explanation:

The amount of mass within the system remained constant during the process for a closed system. A closed system refers to a system that does not exchange matter with its surroundings but allows energy transfer across its boundaries. It undergoes internal energy changes but maintains a constant mass.

A closed system, in thermodynamics, is a physical system that doesn't interact with anything outside the system's boundaries. It can only exchange energy with its environment. In a closed system, there is no exchange of matter across the system's boundaries. Because there is no external exchange, the system's mass remains constant, making it a constant mass system.

When there is no exchange of mass with the environment, the amount of mass within the system remains constant throughout the process. The mass of a closed system remains constant because, in a closed system, the total quantity of mass and energy remains constant. In conclusion, the amount of mass within the system remained constant during the process for a closed system.

The false statement regarding solutions of gases in liquids is: b. More gas can be dissolved in a liquid at higher temperatures.

In general, the solubility of gases in liquids is influenced by temperature and pressure. Statement a is true because more gas can be dissolved in a liquid at lower temperatures. As the temperature decreases, gas molecules have less kinetic energy, making it easier for them to be trapped by the liquid molecules and dissolve. Conversely, at higher temperatures, gas molecules have more kinetic energy and are less likely to dissolve in the liquid, making statement b false.

Statements c and d describe the effect of partial pressure on the solubility of gases in liquids. Increasing the partial pressure of a gas above a liquid (statement c) leads to more gas being dissolved, while decreasing the partial pressure (statement d) results in less gas being dissolved. This relationship is described by Henry's law, which states that the solubility of a gas in a liquid is directly proportional to the partial pressure of that gas above the liquid.

Based on the data provided;

The ideal gas equation relatesthe pressure, volume, moles and temperature of a gas.

The moles of helium gas is calculated using the Ideal gas equation:

n is the number of moles of gas

R is molar gas constant = 8.314 L⋅kPa/Kmol

P is pressure = 239 kPa

T is temperature = 21°C = 294 K

V is volume = 12.8 L

Therefore;

n = PV/RT

n = 239 × 12.8 / 8.314 × 294

n = 1.25 moles

The number of moles of helium gas is 1.25 moles

At peak temperature, T = 46°C = 319 K

Using P1/T1 = P2/T2

P2 = P1T2/T1

P2 = 239 × 319/294

P2 = 259.3 kPa

The pressure at peak temperature is 259.3 kPa

At 42°C, T = 315 K

Using P1/T1 = P2/T2

P2 = P1T2/T1

P2 = 239 × 315/294

P2 = 256.07 kPa

Since the internal pressure is above 256 kPa, the balloon will burst.

The pressure should be reduced to a value less than 256 kPa by reducing the temperature.

The approach of using highly sensitive carbon nanotube adhesive films enables crack growth detection under flexural load in composite structures.

Composite structures, which are widely used in various industries such as aerospace and automotive, are susceptible to internal cracks that can compromise their structural integrity. Detecting and monitoring the growth of these cracks is crucial to ensure the safety and reliability of these structures.

One promising approach to crack growth detection is the use of highly sensitive carbon nanotube (CNT) adhesive films. These films are composed of a network of carbon nanotubes dispersed in an adhesive matrix. When applied to the surface of a composite structure, they can effectively detect the initiation and propagation of cracks.

The high sensitivity of CNT adhesive films is attributed to the unique properties of carbon nanotubes. Carbon nanotubes possess exceptional mechanical, electrical, and thermal properties, making them excellent candidates for crack sensing applications. When a crack initiates and grows in the composite structure, it disrupts the alignment of the carbon nanotubes in the adhesive film, resulting in changes in their electrical conductivity.

By monitoring the electrical conductivity of the CNT adhesive film using appropriate sensing techniques, it is possible to detect and track the growth of cracks in real-time. This enables timely interventions to prevent catastrophic failures and allows for proactive maintenance and repair of the composite structures.

Answer:

The boiling point of water depends on the pressure exerted on its surface. At standard atmospheric pressure, which is about 101.3 kPa, water boils at 100°C (212°F).

However, in this case, the pressure on the surface of water is 30 kPa, which is lower than standard atmospheric pressure. As the pressure decreases, the boiling point of water also decreases.

To determine the boiling point of water at 30 kPa, we can use a steam table or a phase diagram of water. According to a steam table, at 30 kPa, the boiling point of water is approximately 35.3°C (95.5°F).

Therefore, if the pressure on the surface of the water is 30 kPa, the water will boil at approximately 30°C
