The , reactions and transformations that are studied in chemistry are usually the result of interactions between atoms, leading to rearrangements of the chemical bonds which hold atoms together. Active substances are used to clean dishes and surfaces. That is why their upper parts are attracted.
The same goes for any other recipes. Write balanced chemical equations and draw labeled diagrams wherever required. Bottom: Observed results: a small portion of the particles were deflected, indicating. All life forms will be based on it.
