Is the conversion of two compounds into a solution a chemical change?

Not necessarily. There's something called the enthalpy of mixing which can be responsible for lowering the temperature when two substances are mixed even if no chemical reaction occurs. It may also be an endothermic reaction; if there are other signs of a reaction (formation of a precipitate, evolution of a gas, color change, etc.) then it probably is a chemical reaction.

∙ 13y agoA Chemical change is when the color, smell, or texture of a substance changes.
You would call this a qualitative observation.
So yes, this would be considered a chemical change, but only if the color, smell, or texture has changed.

Is precipitate physical change?
Precipitation in weather terms (rain, snow, etc.) is a physical process. Precipitation in chemical terms (e.g. lead iodide falling out of solution) is a chemical change.
What are the 5 characteristics of chemical change?
During a chemical change the structure of molecules (as chemical composition) is changed. Signs of chemical reactions may be: - Gas release - Formation of a precipitate - Change of color - Change of odor - Change of pH - Change of aspect - Change of viscosity - Change of the temperature - Visible formation of new compounds
Is it correct to say that only one observable change accompanies a chemical reaction?
No.Some indicators of a chemical reaction are:- change of color- change of odor- release of a gas- change of the temperature- change of the viscosity- formation of a precipitate- change of general appearance- possible explosion- possible chemiluminescence -formation of new compounds

When small gold flakes are removed from a water solution by filtering the solution is this a chemical change?
No. Filtartion of any kind is not often a change at all, simply a separation of two compounds.
Are compounds broken down into elements by chemical or physical change?
its a chemical change. a physical change does not change the chemical makeup of a substance. it simply changes its form or physical state. examples: ice melting, a tree being chopped down.

What kind of chemical compound do salt in water form?
When salt is mixed in with water, they form a solution. Salt is the solute, and water is the solvent.
