When sugar dissolves in water, the change in entropy is generally positive. This is because the sugar molecules become more dispersed in the solvent, increasing the disorder or randomness of the system.

Is it possible for entropy to be negative and For entropy change to be negative and For entropy production to be negative?
Entropy is always a non-negative quantity according to the Second Law of Thermodynamics, meaning it cannot be negative. Entropy change can be negative for a system that is undergoing a process that decreases its disorder, while entropy production refers to the total increase in entropy within a system and its surroundings, which is always positive or zero but cannot be negative.
Will this entropy change by positive or negative N2 (g) 3h2 (g) 2nh3 (g)?
The reaction N2 (g) + 3H2 (g) → 2NH3 (g) shows an increase in entropy because it involves an increase in the number of gaseous molecules from 2 to 4. Therefore, the entropy change for this reaction is positive.
What could make G become negative at a given enthalpy and entropy?
Changing the temperature
Will this entropy change by positive or negative water heating on a stove?
The entropy, S, will increase with temperature. If there's more kinetic energy in the pot, and the water molecules are flying around faster and faster as a result, there's more chaos and disorder, so a higher value of entropy.
Is N½ g 3H½ g æ 2NH¾ g entropy positive or negative?
The reaction is 2NH₃(g) → N₂(g) + 3H₂(g), and since the number of moles of gas decreases from 2 moles to 4 moles, the entropy change is negative.
Will this entropy change by positive or negative?
If the system becomes more disordered, the entropy change will be positive. If the system becomes more ordered, the entropy change will be negative.
Will this entropy change by positive or negative air is pumped into a tire?
entropy is decreasing, so negative

Will this entropy change by positive or negative n2 g 3h2 g 2nh3 g?
negative
Does a combustion have a negative entropy or positive entropy?
A combustion reaction typically results in an increase in entropy due to the increase in the number of gaseous molecules formed during the reaction, leading to more disorder in the system. Therefore, combustion generally has a positive entropy change.
Predict whether the changes in enthalpy entropy and free energy will be positive or negative for the freezing of water and explain your predictions How does temperature affect the spontaneity?
The changes in enthalpy, entropy, and free energy are negative for the freezing of water since energy is released as heat during the process. At lower temperatures, the freezing of water is more spontaneous as the negative change in enthalpy dominates over the positive change in entropy, making the overall change in free energy negative and leading to a spontaneous process.
When water freezes should the change in entropy be positive or negative and explain?
When water freezes, the change in entropy is negative. This is because in the process of freezing, the molecules become more ordered and arranged into a crystalline structure, leading to a decrease in randomness and disorder in the system. This decrease in disorder corresponds to a decrease in entropy.

Entropy is always a non-negative quantity according to the Second Law of Thermodynamics, meaning it cannot be negative. Entropy change can be negative for a system that is undergoing a process that decreases its disorder, while entropy production refers to the total increase in entropy within a system and its surroundings, which is always positive or zero but cannot be negative.

The reaction N2 (g) + 3H2 (g) → 2NH3 (g) shows an increase in entropy because it involves an increase in the number of gaseous molecules from 2 to 4. Therefore, the entropy change for this reaction is positive.
Why NaCl is very soluble but not CaO is only slightly soluble in water?
NaCl is highly soluble in water due to its ionic nature which allows the ions in NaCl to easily dissociate and interact with the polar water molecules. CaO, on the other hand, is a much less polar compound with strong ionic bonds, resulting in limited interaction with water molecules and lower solubility.
Is Entrophy change in a system that undergoes a spontaneous process positive negative or zero?
Negative entropy is a process or chemical reaction proceeds spontaneously in the forward direction.Positive entropy is a process proceeds spontaneously in reverse.
