What are the symbols used to represent gases liquids solids and aqueous solutions in chemical equations?
Placing a (g), (l), (s), or (aq) after the substances, respectively.
How does entropy change in gas reactions?
Reactions that increase the moles of gas will increase in entropy.
Which of the following has the highest entropy Water Ice Water solution or Water vapor?
Water vapor has the highest entropy because gases generally have higher entropy compared to liquids or solids at the same temperature. Entropy tends to increase with the randomness or disorder of the molecules, so the highly disordered state of water vapor results in higher entropy.
Which phase has the highest entropy?
Gas
Which of the following describes the entropy change of a gas reaction?
If there is an increase in the number of gas molecules, then S > 0.

What is entropy and which phase of matter has the the highest entropy?
Entropy is a measure of the disorder or randomness in a system. The phase of matter with the highest entropy is generally considered to be the gas phase, as the particles in a gas have the highest degree of freedom and randomness compared to liquids and solids.

Can a liquid be a solution?
(Disregarding gases) All solutions are liquids but not all liquids are solutions.
Can solute can be a liquid?
(Disregarding gases) All solutions are liquids but not all liquids are solutions.

(Disregarding gases) All solutions are liquids but not all liquids are solutions.
How does the entropy of the system change when equal volumes of ethanol and water are mixed to form a solution?
The mixing of ethanol and water leads to an increase in entropy because the two liquids become more randomly dispersed at the molecular level compared to when they were separate. The increase in disorder allows for more ways to arrange the molecules, resulting in higher entropy of the system.
What kind of membrane filter is for acuose solutions?
A hydrophilic membrane filter is typically used for filtering aqueous solutions. These filters are designed to be compatible with water-based solutions and have good wetting properties to ensure efficient filtration. They allow liquids to pass through while retaining particles and contaminants.
Are pure liquids solutions?
no
