- 27. is composed of different types of atoms or molecules that are not chemically bonded.
- 28. SuperAtom
- 29. Particle are loosely packed
- 30. is a separation method used to separate out pure substances in mixtures comprised of particles some of which are large enough in size to be captured with a porous material.
- 32. The standard unit of length in both the SI and original metric systems is the
- 33. If a number has no decimal (the decimal is Absent)
- 34. the adhesion of a chemical species onto a surface
- 35. property Any characteristic that can be determined only by changing a substance’s molecular structure.
- 36. standards fixed by international agreement in the International System of Units
- 37. reactioncA process involving the breaking or making of interatomic bonds and the transformation of a substance (or substances) into another.
- 39. If a number has a decimal Present, use the
- 40. The study of chemical processes that occur inside of living organisms.
- 44. refers to whether a compound will burn when exposed to flame.
- 45. is a mixture of two or more chemical substances where the various components can be visually distinguished.
- 46. is the measure of the amount of space occupied by an object.

- 1. The SI base unit of time is the

- 4. refers to whether a compound will react with water or air (chemically stable substances will not react).
- 7. A chemical substance that is made up of a particular kind of atom and cannot be broken down or transformed by a chemical reaction.
- 8. is a type of mixture in which the composition is uniform and every part of the solution has the same properties.
- 9. change A process that causes a substance to change into a new substance with a new chemical formula.
- 10. is a purification process where the components of a liquid mixture are vaporized and then condensed and isolated. In simple distillation, a mixture is heated and the most volatile component vaporizes at the lowest temperature.

- 41. A substance made from two or more elements. Consists of a fixed ratio of chemically bonded atoms. Has unique properties that are different from the properties of its individual elements.
- 42. the temperature at which a substance melts
- 43. of a substance is the ratio of the mass of a sample of the substance to its volume.
