Matter and change
Across
- 2. a blend of two or more kinds of matter, each of which retains its own identity and properties.
- 6. invisible rays that are used to determine microstructures.
- 7. the identification of the components and composition of materials.
- 8. is a measure of the amount of matter and also the measurement you make using a balance.
- 9. the study of substances and processes occurring in living things.
- 11. the study of most carbon-containing compounds
- 13. is a physical change of a substance from one state to another.
- 19. relates to substance's ability to undergo changes that transform it into different substances.
- 21. A change in a substance that does not involve a change in the identity of the substance.
- 22. high-temperature physical state of matter in which atoms lose most of their electrons, particles that make up atoms.
- 24. can thus be defined as anything that has mass and takes up space.
- 26. do not depend on the amount of matter present.
- 27. depend on the amount of matter that is present.
- 29. Matter in this state has neither definite volume nor definite shape.
- 30. The use of mathematics and computers to understand the principles behind observed chemical behavior and to design and predict the properties of new compounds.

- 1. typically involves the production and use of products that improve our quality of
- 3. has a fixed composition and differs from a mixture in the following ways:Every sample of a given pure substance has exactly the same characteristic properties.
- 4. is the smallest unit of an element that maintains the chemical identity of that element.
- 5. the study of non-organic substances, many of which have organic fragments bonded to metals (organometallics).
- 10. The study of the composition, structure, and properties of matter, the processes that matter undergoes, and the energy changes that accompany these processes.
- 12. The substances that react in a chemical change.
- 14. pure substance that cannot be broken down into simpler, stable substances and is made of one type of atom.
- 15. Matter in the this state has a definite volume but an indefinite shape.
- 16. generally carried out to solve a problem.
- 17. Matter in this state has definite volume and definite shape.
- 18. A substance that can be broken down into simple stable substances.
- 20. carried out for the sake of increasing knowledge, such as how and why a specific reaction occurs and what the properties of a substance are.
- 23. the study of the properties and changes of matter and their relation to energy.
- 25. The substances that are formed by the chemical change.
- 28. any substance that has a definite composition.
