Matter and change

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.
