Do the physical properties of water change when a compound is dissolved in water. If so which properties change and why?
The physical properties of water can change when a compound is dissolved in water. The dissolved compound will determine which properties change. Some will change the surface tension, others will change the pH. Many changes are possible.
Is NaCl dissolved in a jar leaving salt behind a chemical change or a physical change?
When NaCl is dissolved in a jar, it undergoes a physical change. This is because the chemical composition of NaCl remains the same, but its physical state changes from a solid to a liquid solution. The salt can be reclaimed by evaporating the liquid and it would still have the same chemical properties as the original NaCl.
Is salt dissolving in a glass of water a chmical change?
A chemical change is when a substance is formed into an entirely new substance, with different properties, as such, a chemical change cannot be reversed. So in answer to your question, salt, in this case the solute (the substance that is being dissolved), is dissolved into water, a solvent (the substance that a solute is dissolved into), so you would think that a chemical change has taken place. But actually, a physical change (when something is changed, but keeps its properties, for example, when you break chalk in two, it is still chalk, only smaller), because if you heat the saltwater, then the water will evaporate, leaving the salt behind, in its original form.
When do the physical and chemical properties change?
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.
Is a compound a physical mixture of a simpler substance?
No, a compound is not a physical mixture; it is a chemical combination of two or more elements that are bonded together in fixed proportions. Unlike a mixture, where the individual components retain their properties and can be separated by physical means, the elements in a compound undergo a chemical change and lose their individual properties. Compounds have distinct characteristics that differ from those of their constituent elements.

Is solubility a physical or chemical propety?
Solubility is a physical property because it is related to a physical, not a chemical, change. When something dissolves, it does not change chemically. It is still the same compound/molecule, etc. when it was not dissolved in the solvent.

What are properties that change?
the properties that change are physical and chemical properties!!! :)
Is the ability to dissolve a physical or chemical change?
Dissolving is a physical change because it does not alter the chemical properties of the substance being dissolved. It involves the separation of particles within a substance without changing their chemical composition.
Is making soap into soap suds a chemical or physical change?
That's a good question, I'm pretty sure that its just a physical change though. I don't think any of the properties of soap are being changed when its dissolved in water. Unless a new compound is being formed between the soap and the water, then its only a physical change. If you don't believe me that a new compound isn't formed, look up dissolving sugar in water. It's pretty much the same idea, and I know for sure that that's counted as only a physical change.
When the elements combine to form compounds what happens to the chemical and physical properties of the elements?
When elements combine to form compounds, the chemical properties change because new chemical bonds are formed between the elements. This can result in new properties for the compound compared to the individual elements. The physical properties may also change, such as its melting point, boiling point, and appearance, due to the arrangement of the atoms and molecules in the compound.
Why do physical properties change when chemicals combine?
Physical properties change when chemicals combine because when you mix chemicals the physical properties changes it identity.
When do the physical and chemical properties change?
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.

Do materials change whenn physical properties are measured?
Yes, materials do change when physical properties are measured.
Have iron and sulfur undergone change in properties after mixing?
No. Making mixtures are physical changes and the chemical substances will not change.
