When a Gas Chromatography (GC) is run on a column packed with a nonpolar stationary phase, hexane will elute first because it has a lower boiling point (69°C) than toluene (110°C).
The purpose of gas chromatography is to separate the components of a mixture based on their distribution between a mobile gas phase and a stationary phase. A GC column consists of a stationary phase coated on the inner walls of a capillary tube and a mobile phase (carrier gas) that is passed through the column. As the sample is introduced into the column, it is carried along by the mobile phase and interacts with the stationary phase. The compounds are separated according to their polarity and their affinity for the stationary phase.
When a column is packed with a nonpolar stationary phase, like in this case, polar compounds are retained on the stationary phase for longer periods, while nonpolar compounds pass through more quickly.Hexane is nonpolar, so it interacts with the stationary phase only weakly. Consequently, it travels through the column more quickly than toluene, which is more polar and interacts more strongly with the stationary phase. Toluene, on the other hand, has more polarizable electrons, which enable it to interact more strongly with the stationary phase. As a result, it travels through the column more slowly than hexane. As a result, hexane elutes before toluene in a Gas Chromatography (GC).

Why
do people have different perceptions towards the same
thing/event/individual? Provide an example to illustrate your idea.
People have different perceptions towards the same thing, event, or individual due to various factors such as individual experiences, beliefs, values, cultural backgrounds, and cognitive processes. These factors shape how people interpret and make sense of the world around them, leading to diverse perceptions.
For example, let's consider a controversial political speech given by a public figure. Different people in the audience may have varying perceptions of the speech based on their pre-existing political beliefs. Those who align with the speaker's ideology might perceive the speech as inspiring and persuasive, while those who hold opposing views might perceive it as divisive or misleading. Their differing perceptions stem from their individual political orientations and biases, which influence how they interpret and evaluate the same speech. Additionally, cultural backgrounds can play a role in shaping perceptions. For instance, a gesture that is considered polite in one culture may be perceived as rude or offensive in another culture. These cultural differences lead to distinct interpretations and perceptions of the same behavior. Furthermore, cognitive processes such as selective attention and cognitive biases contribute to differing perceptions. Two people witnessing the same event may focus on different aspects or interpret them differently based on their attentional biases or cognitive filters.

The idea that inflation by itself reduces people’s purchasing power is called the "quantity theory of money."
The quantity theory of money refers to the relationship between the amount of money in circulation and the level of prices in the economy. According to the theory, if the amount of money in circulation increases while the supply of goods and services remains constant, then prices will rise and the purchasing power of the currency will decrease.
Inflation is an increase in the general level of prices in the economy over a period of time. This means that as the cost of goods and services rises, the purchasing power of money declines. As a result, people are able to purchase fewer goods and services with the same amount of money.

The idea that inflation by itself reduces people’s purchasing power is called the Quantity Theory of Money. Quantity Theory of Money is a monetary theory that postulates the relationship between money supply and the price level of an economy. According to this theory, changes in the supply of money cause proportional changes in the price level of an economy. This means that a change in money supply brings about a change in the level of prices.According to this theory, an increase in money supply relative to goods and services will lead to a corresponding increase in the price level of goods and services in the economy. This will, in turn, reduce the purchasing power of money, as a larger amount of money is required to purchase goods and services. Inflation, in this sense, is the result of too much money chasing too few goods. Therefore, it is the Quantity Theory of Money that suggests that inflation by itself reduces people's purchasing power.The Quantity Theory of Money, however, does not take into account many other factors that can influence the price level of goods and services in an economy. For instance, it does not factor in the possibility that changes in money supply may not necessarily lead to a corresponding increase in prices, as there may be a lag between the two.

Vienna model be adopted in Hong Kong? Why?
Collaborative housing is a form of housing that is jointly developed, designed, and operated by the people who live in it, such as cooperatives, co-housing, and collective housing.
Home Ownership Scheme (HOS) in Hong Kong has been launched to allow individuals and families who meet the eligibility criteria to buy public housing units at a discounted price. HOS has more in common with affordable housing initiatives in other countries than with social housing in Vienna. Social housing in Vienna is government-funded and provided at reduced rents to tenants who have low or no income. They are distinguished from affordable housing initiatives by their social aims and scope. Because social housing in Vienna is a product of a long-term and highly customized solution to the city's housing shortage, it may not be directly transferable to Hong Kong. Collaborative housing initiatives may be more compatible with Hong Kong's urban environment and could provide a new model of housing supply that is more flexible, innovative, and responsive to local needs.

what a priori justification is there for assuming recombination-generation takes is neglible throughout the depletion region
As a result, the probability of ionization decreases, and the recombination rate decreases. Similarly, the generation rate decreases because there are fewer ionized atoms available. As a result, the recombination-generation rate becomes negligible far from the junction. This is why it is a priori justified to assume that recombination-generation is negligible throughout the depletion region. The justification is based on the fact that far from the junction, there are not enough ionized atoms to produce significant recombination or generation.
The a priori justification for assuming recombination-generation takes is negligible throughout the depletion region is the following:When a p-n junction is formed, a depletion region is formed where the majority charge carriers (electrons or holes) are depleted, leaving behind ionized atoms. This region has no free carriers of either type and is therefore responsible for the rectifying properties of the junction. Recombination is the process of free charge carriers combining to form a bound state and ceasing to conduct current. On the other hand, generation is the process of a bound state breaking apart and releasing a free charge carrier.Recombination-generation is the process by which a free electron and a hole, which are separated in the depletion region, recombine, leading to a decrease in the number of minority carriers and an increase in the number of majority carriers. In a p-n junction under forward bias, the majority carriers are pushed into the depletion region, where they experience a voltage gradient and therefore accelerate. As a result, their energy increases, and they have a higher probability of ionizing atoms in the depletion region, producing free carriers. Therefore, recombination and generation are significant near the junction under forward bias.However, far from the junction, the voltage gradient decreases, and the energy of the carriers decreases. As a result, the probability of ionization decreases, and the recombination rate decreases. Similarly, the generation rate decreases because there are fewer ionized atoms available. As a result, the recombination-generation rate becomes negligible far from the junction.

The attractions between adjacent atoms due to constantly fluctuating electron clouds are called van der Waals forces.
Van der Waals forces are relatively weak compared to chemical bonds but play a significant role in determining the physical properties and behavior of substances. These forces arise from temporary imbalances in electron distribution, resulting in the creation of instantaneous dipoles and inducing similar dipoles in neighboring atoms or molecules. The three types of van der Waals forces are London dispersion forces, dipole-dipole interactions, and hydrogen bonding. London dispersion forces are present in all atoms and molecules and arise from the temporary fluctuations in electron distribution. Dipole-dipole interactions occur between polar molecules, where the positive end of one molecule attracts the negative end of a neighboring molecule. Hydrogen bonding is a specific type of dipole-dipole interaction that occurs when hydrogen is bonded to highly electronegative atoms such as oxygen, nitrogen, or fluorine.

mechanical work is performed in all of these types of muscle activity (contraction) except for
Mechanical work is performed in all types of muscle activity except for isometric contractions.
Muscle contractions can be broadly categorized into three types: isotonic, isometric, and auxotonic. Isotonic contractions involve the change in muscle length, and they can be further divided into concentric and eccentric contractions. Both concentric and eccentric contractions involve mechanical work as the muscle shortens or lengthens, respectively, against a load. Auxotonic contractions involve a combination of isometric and isotonic contractions, and they also require mechanical work.
However, isometric contractions do not involve a change in muscle length or joint movement. In isometric contractions, the muscle generates force without causing movement or mechanical work. The muscle contracts, but there is no change in length or external movement. Therefore, mechanical work is not performed in isometric contractions.
