a solid spred through a liquid
If you mix things together, you get a mixture.
a chemical change proude a different kind of matter
Evolution is not a cause of genetic change: it is the effect of genetic change.
Mixture
There's no set formula for 'dust'. It depends on what kind of dust it is.
Water boiling is a phase change, which is a kind of physical change.
chemical change
chemical change
The batteries are undergoing a chemical change, particularly during the charging process when hydrogen and oxygen gases can be generated. This happens as a result of electrolysis of water within the battery, leading to the production of these gases which can form an explosive mixture if not properly ventilated.
Chocolate milk is a mixture called a colloid.
A mixture is a solution of a compound or the liquid state of a compound. When you make a solution of a salt, the salt will solute in the solvent, and go to the ionic state. Example, NaCl in water: NaCl(s) -> Na+(aq) + Cl-(aq)
Macaroni is a mixture not a change.
When two substances are mixed, the individual particles come into contact and can interact chemically or physically with each other. This can result in the formation of a new substance, a change in physical properties, or a change in concentration of the components in the mixture.
A mixture
A physical change is needed to separate a mixture into its components. This can be achieved through processes like filtration, distillation, chromatography, or evaporation, which rely on the differences in physical properties between the components of the mixture.
The result is a physical change, specifically a dissolution process where the powder particles mix with water to form a homogeneous mixture. This is a reversible change, as you can separate the components by evaporating the water.
Solution is the mixture and the result of a solute and a solvent
