When a liquid crystallizes to a solid, the sign of entropy is negative. This is because the process involves a transition from a disordered state (liquid) to a more ordered state (solid), resulting in a decrease in the randomness or disorder of the system. Consequently, the entropy of the system decreases during this phase transition.
What else can I help you with?
In a chemical reaction two gases combine to form a solid What do you expect for the sign of S?
The entropy change (ΔS) for this reaction would typically be negative, as gases have higher entropy than solids. This indicates a decrease in disorder or randomness, which is expected when gases combine to form a solid.
Is the evaporation of water a potential sign of a chemical change?
No, evaporation causes a change in the state of matter (liquid to solid) which is a physical change
Will this entropy change by positive or negative n½ g 3h½ g æ 2nh¾ g?
To determine the change in entropy for the reaction represented by the expression ( n^{1/2} g , + , 3h^{1/2} g , \leftrightarrow , 2nh^{3/4} g ), we need to consider the number of moles of gas on each side of the equation. If the total number of gaseous moles increases in the products compared to the reactants, the entropy change will be positive, indicating an increase in disorder. Conversely, if the number of moles decreases, the entropy change will be negative. Without specific coefficients or more context, we cannot definitively conclude the sign of the entropy change.
What does a solid solute do in a liquid?
If the solvent is a liquid, gases, liquids, and solids can be dissolved. Examples are:Gas in liquid: Oxygen in water.Cation of ions). Note also that the visible bubbles in carbonated water are not the dissolved gas, but only an effervescence; the dissolved gas itself is not visible since it is dissolved on a molecular level.Liquid in liquid: Alcoholic beverages are basically solutions of ethanol in water.Petroleum is a solution of various hydrocarbons.Solid in liquid: Sucrose (table sugar) in waterSodium chloride or any other salt in water forms an electrolyte: When dissolving, salt dissociates into ions.Counterexamples are provided by liquid mixtures that are not homogeneous: colloids, suspensions, emulsions are not considered solutions.Body fluids are examples for complex liquid solutions, containing many different solutes. They are electrolytes since they contain solute ions (e.g. potassium and sodium). Furthermore, they contain solute molecules like sugar and urea. Oxygen and carbon dioxide are also essential components of blood chemistry, where significant changes in their concentrations can be a sign of illness or injury.
What is the liquid that accumulates in the abdomen called?
The liquid that accumulates in the abdomen is called ascites. It can be a sign of liver disease, heart failure, kidney disease, or certain types of cancer. Treatment involves addressing the underlying cause and sometimes draining the fluid.
Is the neon in a sign a solid gas or liquid?
Gas

For an equilibrium that lies far to the product side and has a positive entropy change which of the following could be true?
The sign of ΔG° for the forward reaction is less than 0. The reactant could be a solid and the products could be gasses.
Is the evaporation of water a potential sign of a chemical change?
No, evaporation causes a change in the state of matter (liquid to solid) which is a physical change
Melting point of water?
The melting point of a substance is the temperature at which solid state of a substance co exist in equilibrium with its liquid state. It is also called the freezing point (melting is the same process as freezing, just in the opposite direction, and so the temperature is identical).See Web LinksSee the Web Links for "Answers.com: Melting point" below for more information.The melting point is a point where a solid begins to heat and lose mass. It generally changes from a solid state to a liquid state.
What happens when the motion of the molecules in a solid or liquid becomes stronger than the attraction of the molecules to each other?
The particles start to give away and they break away from the attraction. This can be seen when boiling water, because when it boils there are bubbles and that is a sign that a new state is being made (gas) and that the particles are breaking away
Is there presence of liquid water on Mars?
They had found ice on mars but no sign of a liquid
Is the less than sign dotted or solid?
dotted
What is the state symbol for sodium hydroxide?
According to the MSDS HCl is a Liquid. It is also found dissolved in water.

Yes or it may be a sign of hormonal imbalance
