A substance changing state (i.e. solid to a liquid) is not a chemical change as the composition of the substance has not changed at all. The particles' energy and distance from each other is the only thing that is altered.
When HCl and phenolphthalein are mixed, a chemical reaction occurs leading to a change in the color of the solution (from pink to colorless). This is a chemical change as new substances are formed with different properties than the original substances.
A solid formed from liquid reactants during a chemical reaction is called a precipitate. This occurs when two soluble reactants mix and a solid compound is formed that is insoluble in the reaction medium.
When a precipitate forms, cations and anions in aqueous solutions combine to form an insoluble ionic solid. This is specifically classified as a double replacement reaction and takes the form AB + CD --> AD + CB.
A chemical reaction occurs where iron III iodide is formed and potassium nitrate is produced as a byproduct. The balanced chemical equation for this reaction is 2KI + Fe(NO3)3 -> 2KNO3 + FeI3. Iron III iodide is a dark brown solid, whereas potassium nitrate remains in solution.
When salt is combined with water, a chemical reaction called dissolution occurs. This reaction involves the breaking of the ionic bonds in the salt crystals, causing the salt molecules to separate and disperse evenly throughout the water, creating a saltwater solution.
When a solid falls out of solution, it is called a precipitate. A precipitate is formed when a chemical reaction occurs in a solution and the product that is made is insoluble.
A chemical reaction occurs where lithium sulfate and ammonium chloride are formed. These products are both soluble in water and remain in solution. The reaction is: LiCl + (NH4)2SO4 → Li2SO4 + 2NH4Cl.
The solid that forms out of a solution is called a precipitate. It is formed when the solubility limit of a substance in a solution is exceeded, causing it to separate out as a solid. This process is known as precipitation.
When HCl and phenolphthalein are mixed, a chemical reaction occurs leading to a change in the color of the solution (from pink to colorless). This is a chemical change as new substances are formed with different properties than the original substances.
A solid formed from liquid reactants during a chemical reaction is called a precipitate. This occurs when two soluble reactants mix and a solid compound is formed that is insoluble in the reaction medium.
The formation of a precipitate occurs when two solutions react to form an insoluble solid that separates out from the solution. This solid is known as the precipitate. It is a common indicator of a chemical reaction taking place in a solution.
When a precipitate forms, cations and anions in aqueous solutions combine to form an insoluble ionic solid. This is specifically classified as a double replacement reaction and takes the form AB + CD --> AD + CB.

Reaction in which bubbles are formed in solvent
There is NO chemical reaction at all when you dissolve NaCl into water. Dissolving is NOT chemical but a physical change of state.When however a reaction occurs, the original compound is called (one of) the reactant(s) and the compound(s) formed is (are) the product(s) of a chemical reaction.
A chemical reaction occurs when the bonds of the reacting compounds are broken and new combinations are formed. This process involves the rearrangement of atoms to form new molecules with different chemical properties.
There is no chemical reaction between isopropanol and water, they simply mix.
