A mixture of nitrogen, oxygen, fluorine, and neon are in a container which has a tiny, tiny pinhole leak. Which element leaks the slowest from the container?.

Answers

Answer 1

A mixture of nitrogen, oxygen, fluorine and neon are in a container which has a tiny, tiny pinhole leak. The slowest element to leave the container is fluorine.

Gas output is expressed as:

Rate ∝ 1 / √M

rate of effusion is inversely proportional to the square root of the molecular weight.

molecular weight of nitrogen = 14amu

molecular weight of oxygen = 16 amu

Molecular weight of fluorine = 19amu

The rate of effusion with increasing molecular weight. Fluorine is therefore the element that escapes the slowest from the container. There is a mixture of nitrogen, oxygen, fluorine and neon inside the container with a very small leak. elements fluorine are the slowest to leak out of the container

why might the method used (in this demonstration) not be suitable for determining the water of hydration for all hydrates?

Answers

The anhydrous cpd could significantly decompose into a gaseous product or significantly react w/something in the air.

Water of hydration is water that is stoichiometrically bound into a crystal. While the water is found within a crystal, it is not directly bonded to a metal cation. Crystal salts containing water of hydration are called hydrates.

Many crystals form from particles dissolved in water or aqueous solutions. It's common for some of that water to be incorporated into the framework of a crystal. Usually, heating a crystal drives off water of hydration, but the structure of the crystal is lost.

Aqueous ammonia is commercially available in a solution that is 28% (w/w) ammonia. What is the mole fraction of ammonia in such a solution?.

Answers

The mole fraction of ammonia in such a solution is 0.291.

What is an aqueous solution?

Water containing one or more dissolved substances is called an aqueous solution. Aqueous solutions may have dissolved particles, gases, or other liquids. A mixture must be stable to be a true solution.

What is Mole Fraction?

The term "mole fraction" is used by dividing the total number of moles in a given mixture by the number of molecules of a particular component. The concentration of a solution is expressed as this ratio.

28% w/w means that 100 g of ammonia solution contains 28 g of ammonia.

water = 100-28 = 72 g

mole NH3 = 28/17 = 1.647

moles of water = 72/18 = 4

Sum of moles = 4+1.647 = 5.647

Ammonia mole fraction = mol NH3/total moles

= 1.647 / 5.647 = 0.291

Therefore, the molar fraction of ammonia in such a solution is 0.291.

The liquid water that was on the object evaporates to water vapour and diffuses into the air, which is why a wet object dries.

Drying wet clothing causes the water molecules on the surface to acquire latent heat of vapourization, turn into vapour, and separate from the fabric's surface. Evaporation is the name of this process.

(Site 1)site 1 under Cultural Contexts and Values in CommunicationA culture does not have to contain an ethnic context, although ethnic groups do form a culture. In terms of communication, culture refers more to explicit forms of communication and expectations of relating within a group. As such, there are high-context cultures and low-context cultures.Two boys in a Buddhist monastery. There are statues of Buddha along the walls. The two boys are wearing orange robes and are barefoot. They are carrying a jug of water and a tea kettle.These boys live in a Buddhist monastery, a high-context environment. There, long-term relationships are built, and those who do not live within the monastery are outsiders.In everyday life, you pass through several different cultures as you move through family situations, work or school situations, and public or private venues. How you communicate within these cultures differs. Communication depends on the formation of the association, how people within the culture interact, shared or private space, time constraints, and information sources.High-Context Communication EnvironmentsThree diagrams of lines of communication. There are three groups of circles, triangles, and ovals. There is one line that extends between each group. There are multiple lines extending to each circle, triangle, and oval within the individual groups.The lines of communication in high-context cultures are contained within small groups. There are few lines of communication between members outside each group.A high-context culture is a small, close-knit group such as a family, a group of friends, a religious congregation, or a handful of people eating together around a table. Often, these cultures are based on long-term relationships. The group has strong boundaries and considers those outside the group as outsiders. Knowledge and ways of imparting knowledge are understood because people within the group share forms of communication. New people are not as easily accepted in high-context cultures. For example, a Buddhist monastery is a closed environment in which all members are easily accepted, but outsiders are not. Monks know the rules, and they have a leader, an abbot, who is the central authority. Monks live and work together in a communal space, communicate face to face, and share common rules and beliefs. The relationships among monks are long term.Low-Context Communication EnvironmentsA diagram of low-context communication. An oval has lines extending to multiple shapes.Communication in low-context groups is more public and open to outsiders.Low-context groups communicate differently from high-context groups. The rules of communication are formalized, open to the public, and general. Rules are set by an external group, such as a sports authority, a public airport commission, or a state agency. There may be smaller, more closely aligned groups within the larger, low-context groups. Communication exists through loose connections over shorter time periods and is more task oriented than person oriented. Knowledge transfer is clearly defined and arranged, such as a set of laws or socially acceptable behaviors. A national football organization would be an example of a low-context communication culture. The group has regulations defined by an authority that all players and coaches must adhere to. The organization may contain many teams, and members of those teams fluctuate season by season. The task of winning a football game is the central focus, and much communication and learning among members revolves around that task.All cultures contain both high- and low-context modes. A town may be a low-context culture. Within the town's structure, there exists a core governing group, a town council, that formulates regulations. The town has a central figure or leader, the mayor. That mayor communicates between groups of citizens, business representatives, and other authorities or entities in the town, such as a school board or parks and recreation commission. Communication always exists at a variety of levels from highly interpersonal, one-on-one relationships to mass meetings in which a number of speakers provide information and the number of listeners is great.Keywords: relationship, high-context, low context, communication in which of these molecules or ions does the presence of nonbonding electron pairs produce an effect on molecular shape, assuming they are all in the gaseous state? check all that apply. in which of these molecules or ions does the presence of nonbonding electron pairs produce an effect on molecular shape, assuming they are all in the gaseous state?check all that apply. geh4 pi3 hi hcn scl2 What are the 5 main steps for how a bill becomes a law ?. in an organizational context, transformational leaders build trust in their leadership and the attainability of their goals by First change the given pattern into a vector w of zeros and ones by turning each shaded square into a 1 and each unshaded square into a 0 and then lining up each column below the column before it.
