What else can I help you with?
Indicate whether the rate of dissolving increases or decreases for each of the following. a)heat the solution b)stir the solution c)grind the solution?
a) Increases - Heating the solution usually increases the rate of dissolving because it provides more energy to the particles, causing them to move faster and interact more. b) Increases - Stirring the solution increases the rate of dissolving by ensuring that fresh solvent comes into contact with the solute continuously, promoting a more efficient dissolution process. c) Increases - Grinding the solution usually increases the rate of dissolving by increasing the surface area of the solute particles, allowing for more contact with the solvent and speeding up the dissolution process.
Can a liquid dissolve a gas?
Yes, a liquid can dissolve a gas. When a gas comes into contact with a liquid, the gas molecules can be absorbed and become distributed throughout the liquid, forming a solution. Examples of this include carbon dioxide dissolving in water to make carbonated water or oxygen dissolving in blood.
What is the difference between a naturally occurring solution and a manufactured or processed solution?
The only difference is the origin of the solution. A naturally-occurring solution is one that comes about by natural processes with non human interference. A manufactured or processed solution is one that is created by industrial production, in a laboratory, or from other human processes.
Why does water turn brown when mixed with iodine?
When iodine is mixed with water, it forms a solution that appears brown due to the interaction between iodine molecules and water molecules. The brown color comes from the absorption of light by the iodine molecules, which causes them to appear brown to our eyes.
Wh where does chemical energy come from?
Chemical energy comes from the breaking or forming of chemical bonds in molecules. When bonds break, energy is released, and when bonds form, energy is absorbed. This energy comes from the arrangement of atoms and their interactions within a molecule.
When the dissolving rate equals the rates at which molecules come out of solution the solution is in?
When the dissolving rate equals the rate at which molecules comes out of solution the solution is in 'equilibrium'.
When you dissolve solid sugar into water this new solution will taste sweet the sugar went through a chemical change?
Dissolving sugar in water is a physical change, not a chemical change. The sugar molecules are still the same chemical substance before and after dissolving; they have simply spread out in the water. The sweet taste comes from the sugar molecules interacting with your taste buds, not from a chemical change taking place.

What is an adsorbate and give an example?
An adsorbent is a substance that sits on top of a solution, instead of dissolving into it. An example of this type of substance is the silica gel that comes in certain products you buy.
Can a liquid dissolve a gas?
Yes, a liquid can dissolve a gas. When a gas comes into contact with a liquid, the gas molecules can be absorbed and become distributed throughout the liquid, forming a solution. Examples of this include carbon dioxide dissolving in water to make carbonated water or oxygen dissolving in blood.
Dissolving a solid in water usually an endothermic change?
Dissolving a solid in water is typically an exothermic process because energy is released when the solute particles mix with the solvent particles. The energy released usually comes from the formation of new intermolecular bonds between the solute and solvent molecules.
What could be observed if a cell is placed in salt solution?
hi!!! if a cell is placed inside a salt solution then cell boundary going for raptured due to the water molecules comes out from cell to maintain the cons. equilibria.
How is litmus solution is prepared?
Litmus solution is a mixture of dyes dissolved in water.

What does the word molecules?
Molecules are very tiny particles.It comes from the word which means "mass".
How can water be re-obtained from the solution?
Heat the solution and condense the steam that comes off.
