matter

3. Pertaining to the properties and behavior of matter and energy in the absence of chemical changes.
5. Compounds formed when elements combine with oxygen, often found as minerals or components of rust.
6. A chemical compound formed from the reaction between an acid and a base, composed of cations and anions.
7. A homogeneous mixture of one or more substances (solute) dissolved in a solvent.
9. Anything that has mass and occupies space, including solids, liquids, gases, and plasma.
11. Relating to factors or properties that come from outside or are not inherent to a substance or system.
12. A pure substance made up of only one type of atom, characterized by its unique chemical properties.
15. A mixture with fine particles suspended in a continuous medium, typically between a solution and a suspension in terms of particle size.
17. Relating to compounds or interactions involving ions, which are atoms or molecules with an electric charge.
19. Substances that do not contain carbon-hydrogen (C-H) bonds, typically minerals and compounds without organic structures.

1. A combination of different substances that are not chemically bonded together.
2. The fourth state of matter, consisting of highly charged particles with high kinetic energy.
4. A mixture with visibly different components that are not evenly distributed throughout.
8. Related to the study of the composition, structure, properties, and changes of matter involving chemical reactions.
9. An element that has properties intermediate between metals and nonmetals on the periodic table.
10. A heterogeneous mixture in which solid particles are suspended in a liquid or gas and may settle over time.
13. A state of matter with a definite volume but no definite shape, where particles are free to move past one another.
14. A state of matter with both a definite shape and volume, where particles are closely packed together and have limited motion.
16. A substance that releases hydrogen ions (H+) in solution, typically with a sour taste and the ability to corrode metals.
18. Substances that can accept hydrogen ions (H+) in solution, often with a bitter taste and slippery feel.
