In a chemical change, the particles that change are atoms and molecules. Bonds between atoms break and form new connections, leading to the formation of different substances with unique chemical properties. The number and type of atoms remain the same before and after the reaction, but their arrangement and bonding change.
When a solid is heated its particles melts and change into liquid
When combined with other substances, iodine particles can change through chemical reactions, forming new compounds or mixtures. The arrangement of iodine particles may also change depending on the nature of the interaction, such as forming ionic or covalent bonds with other elements. In some cases, the physical state of iodine (solid, liquid, or gas) can shift, affecting how the particles are organized. Overall, both the particles and their arrangement can change when iodine interacts with other substances.
A change in the arrangement or energy of a material's particles refers to a phase change or a thermal process, where particles may transition between solid, liquid, or gas states. This change often involves the absorption or release of energy, which affects the kinetic energy and interactions between particles. For example, heating ice causes its particles to gain energy, resulting in a transition to liquid water. Conversely, cooling water can lead to the formation of ice as particles lose energy and arrange into a solid structure.
Temperature affects the average kinetic energy of particles. As temperature increases, particles have higher kinetic energy, which can impact their speed, collisions, and interactions with other particles.
When ice melts, the solid ice particles transition into liquid water particles. This phase change occurs due to the absorption of heat energy, causing the ice particles to break their rigid structure and flow more freely.

- color change - precipitate - irreversible - heat given off - bubbles formed
The telephone country code for Argentina is +54. The area code for Chamical is 03826, or +54 3826 in international format.

There is a colour change because like fats, Sudan IV is not soluble in water. So when you add Sudan IV to lipids, it will break down therefore the chamical reaction that takes place is the colour change.
K is the symbol (not chemical formula) for potassium
The chemical name for P6O2 is diphosphorus hexoxide.
Gas has fast moving particles.
The particles of gas have more energy and are less tightly packed than particles in solids. This allows gas particles to move freely and change position easily, while solid particles are held in a fixed position by strong intermolecular forces.
