The pillar of sustainability broken by recycling electronics in India is environmental sustainability. Implementing a law that restricts electronics recycling to the US would not necessarily be the most effective solution, as it overlooks the complex global dynamics of electronic waste management.

Recycling electronics in India often involves improper disposal methods, such as burning or dismantling without proper safety measures. This leads to environmental pollution, including the release of hazardous substances into the air, soil, and water, thus violating the principle of environmental sustainability.

However, simply mandating that electronics can only be recycled in the US may not be the most optimal solution. Electronic waste is a global issue, and restricting recycling to a single country disregards the fact that electronic products are manufactured and consumed worldwide. A more comprehensive approach to addressing electronic waste would involve international cooperation, strict regulations, and monitoring of recycling practices to ensure they meet environmental standards.

Efforts should focus on improving recycling practices globally, including promoting responsible electronic waste management, developing sustainable recycling infrastructure in multiple countries, and encouraging the adoption of safe and environmentally friendly recycling practices. This approach would foster global sustainability and address the challenges associated with electronic waste disposal more effectively than a geographically limited restriction.

Explanation:

True. hydrogen bonds in alcohols are generally stronger than those in amines due to the higher electronegativity of oxygen compared to nitrogen.

Hydrogen bonding is a type of intermolecular force that occurs when a hydrogen atom is bonded to a highly electronegative atom (such as oxygen, nitrogen, or fluorine) and is attracted to another electronegative atom in a different molecule. In both amines and alcohols, hydrogen bonding can occur due to the presence of hydrogen atoms bonded to nitrogen and oxygen, respectively.

However, the strength of hydrogen bonds can vary depending on the electronegativity and size of the atoms involved. In general, hydrogen bonds in alcohols tend to be stronger than those in amines due to the higher electronegativity of oxygen compared to nitrogen. This difference in electronegativity leads to a greater polarity in the O-H bond, resulting in stronger hydrogen bonding interactions.

The statement "hydrogen bonds in amines are weaker than those in alcohols" is false. Amines have a stronger hydrogen bonding than alcohols.

Amines and alcohols have one or more hydroxyl (-OH) and amino (-NH2) groups in their molecular structure. These functional groups in amines and alcohols allow hydrogen bonding to occur. Hydrogen bonding occurs when the H atom attached to N, O, or F of one molecule is attracted to the lone pair of electrons on N, O, or F of another molecule.

In general, nitrogen is more electronegative than oxygen, resulting in a stronger bond between the nitrogen in the amine group and the hydrogen, making the hydrogen bonding in amines stronger than the hydrogen bonding in alcohols. Therefore, the statement that "hydrogen bonds in amines are weaker than those in alcohols" is false.

Surfactants reduce the activation energy of the reaction to exert catalytic effects, making the catalyzed reaction more energetically favorable.  Option (C) is correct "Reducing the activation energy of the reaction".

Surfactants are chemical compounds that lower the surface tension between two liquids or between a liquid and a solid, which makes them useful in a wide range of industrial and domestic applications. They have the ability to exert catalytic effects through the reduction of activation energy of the catalyzed reaction.
Explanation:Surfactants are molecules that have both hydrophilic (water-loving) and hydrophobic (water-hating) ends. They reduce surface tension and interfacial tension between liquids and solids by adsorbing at the interface. In catalytic reactions, surfactants reduce the activation energy of the reaction by facilitating the movement of reactants from one phase to another or by stabilizing the transition state. This increases the rate of the reaction and decreases the activation energy. Thus, surfactants can act as effective catalysts for a variety of reactions.
Catalysis is the process of increasing the rate of a chemical reaction by adding a substance called a catalyst. A catalyst is a substance that increases the rate of a reaction without being consumed or permanently changed in the process. In a catalyzed reaction, the catalyst lowers the activation energy required for the reaction to occur. This allows the reaction to proceed at a faster rate, often with lower temperatures and pressures than would otherwise be required.

The ionization of a drug increases water solubility and decreases lipid solubility. A weak acid becomes less water-soluble and more lipid-soluble at acidic pH due to the fact that the more the ionization of the acid, the more hydrophilic it becomes and, therefore, the more it is likely to be dissolved in water.

Ionization is a chemical process in which the net electric charge of an atom or molecule changes. A substance will ionize into positive and negative ions when it comes into contact with an ionizing agent such as water. The degree of ionization is affected by the pH of the solution, which is a measure of its acidity or basicity.

Water is polar, meaning that it has a positively charged side and a negatively charged side, allowing it to dissolve polar compounds (compounds that have a charge). Since an ionized molecule will have a charge, it will be more water-soluble. On the other hand, lipid solubility is determined by the compound's polarity. Since lipids are non-polar, a non-ionized molecule is more likely to dissolve in a lipid solution.

The flow of chilled water through the cooling coil is regulated by a control valve.

In HVAC systems, the flow of chilled water through the cooling coil is regulated by a device called a control valve. The control valve is responsible for adjusting the flow rate of chilled water based on the cooling demand of the system. It ensures that the right amount of chilled water is supplied to the cooling coil to maintain the desired temperature in the conditioned space.

The control valve is typically controlled by a building automation system or a thermostat. These devices monitor the temperature in the conditioned space and send signals to the control valve to open or close. When the temperature rises above the set point, the control valve opens to allow more chilled water to flow through the cooling coil, cooling the air. Conversely, when the temperature falls below the set point, the control valve closes to reduce the flow of chilled water.

Hydrophobic interactions are more powerful than other weak intermolecular forces. If the interacting molecules are in an aqueous solvent, the hydrophobic interaction is relatively strong.

An intermolecular forces is an attractive force that exists between the positive components (or protons) of one molecule and the negative components (or electrons) of another molecule. This force influences a substance's physical and chemical properties. The boiling point of a substance is proportional to the strength of its intermolecular forces; the stronger the intermolecular forces, the higher the boiling point.

We can compare the intermolecular forces of different substances by comparing their boiling points. This is because the heat absorbed by the substance at its boiling point is used to break these intermolecular forces and convert the liquid to vapor. Intermolecular forces are responsible for the majority of matter's physical and chemical properties.
