- 5. is one of the states of matter. is a substance which is not solid but which flows and can be poured, for example water.
- 6. chemistry together with physics
- 8. A substance with high electrical conductivity, luster, and malleability, which readily loses electrons to form positive ions (cations).
- 10. is a way of expressing numbers that are too big or too small to be conveniently written in decimal form. It is in counting the number of significant figures.
- 12. is the process by which water changes from a liquid to a gas or vapor.
- 15. is the transition from the solid phase to the gas phase without passing through an intermediate liquid phase.
- 17. can be separated into simpler substances, but only through chemical means.
- 22. is the degree to which a chemical substance or a particular mixture of substances can damage an organism.
- 23. whether the substance can be easily decomposed or not.
- 26. whether it will break into charged particles when in solution with water or not.
- 27. is a type of homogeneous mixture that does not separate on its own.
- 28. is the process of separating elemental metals from other particles in a mixture.
- 31. occurs when a substance is converted to a new substance.
- 34. any of a group of rare gases that include helium, neon, argon, krypton, xenon, and usually radon. It is called inert gas.
- 36. elements that are not able to conduct electricity or heat very well.
- 37. is the ability of a substance to react with other substances such as air, water, and base.
- 39. is the smallest object that retains the properties of an element.
- 42. are those that can be measured and oserved without changing the composition of the substance.
- 43. is a material made up of two or more different substances which are physically combined.
- 45. is the study of matter and the chemical reactions between substances.
- 46. whether the material is more active or less active than other members of its chemical family.
- 47. study of chemical processes within and relating to living organisms. It is the chemistry of life.
Down
- 1. refers to the phase change from gas to solid.
- 2. also called a solution.
- 3. Its particles are unstable since they settle down after a short period of time.
- 4. is one of the four fundamental states of matter. A substance or matter in a state in which it will expand freely to fill the whole of a container, having no fixed shape and no fixed volume .
- 7. whether it reacts with acids, bases, and oxygen, gas, or not.
- 8. is an element intermediate in properties between the typical metals and nonmetals.
- 9. is the process by which water vapor in the air is changed into liquid water.
- 11. is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension.
- 13. occurs when the internal make-up of the matter stays the same, even after the change - only shape,size, and state are altered.
- 14. is the positively charged center of the atom consisting of protons and neutrons.
- 16. is the process by which a substance changes from the solid phase to the liquid phase.
- 18. is a process in which a conversation factor written in a form of ratio is used to change the units given in the data to the units desired.
- 19. is the process where a mixture is separated through spinning.
- 20. is a particle with a positive charge that is in the nucleus of an atom.
- 21. is the study of the structure, properties, composition, reactions, and preparation of carbon-containing compounds, which include not only hydrocarbons but also compounds with any number of other elements.
- 24. is that branch of chemistry in which samples are analyzed in order to determine their components qualitatively and quantitatively.
- 25. are the smallest of the particles that make up an atom, and they carry a negative charge.
- 26. also called as intrinsic property.
- 29. is the simplest form of matter since it is compose of only one atom. It is a pure substance that cannot be decomposed into a simpler substance by ordinary chemical means.
- 30. is any substance that has mass and takes up space by having volume.
- 32. also called as extrinsic propery.
- 33. the branch of chemistry that deals with inorganic compounds.
- 35. is the technique of heating a liquid to create vapor which is collected when cooled separate from the original liquid. It is a process of separating a homogeneous mixture composed of two substances with boiling points.
- 38. is one of the Four fundamental states of matter which maintains a fixed volume and shape and its particles are very close to each other.
- 40. The process through which a substance changes from a liquid to a solid.
- 41. is a process of separating the components of a suspension.
- 44. is a method by which a mixture is separated by distributing its components between two phases. Coffee filter can be used in separating mixtures.
- 45. whether the substance undergoes combustion or not.
