CSET Science: Chemistry

Subjects : cset, science, chemistry
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Metals like calcium that produce alkaline solutions when combined with water. Part of Group IIA. Have two electrons in their outer shells






2. The conversion of a gas back into a liquid






3. Carbons that consist of both hydrogen and carbon atoms and can be alkanes - alkenes - akynes - adn aromatics






4. The idea that 1. gaes are made up of particles - 2. gas atoms do not exhibit intermolecular attraactions or repulsions - 3. gas particles are in continuous random motions - 4. collisiosn between two gas particles is not dissipated - and 5. the averag






5. The way of ordering the periodic table based on how many protons there are






6. Radioactive decay in which a beta particle - aka an electron - is emitted






7. The outer electron in a shell






8. Distilled water - which has the ph level of 7






9. Ammonia






10. The center of an atom - which contains protons and neutrons






11. Hydrocarbons taht also include oxygen - like alcohols - carbohydrates






12. The way a periodic table is ordered in columns based on how many electrons are in the outer shell






13. Gases like neon and helium that do not interact with other elements because they havea complete valence shell






14. A specific type of double deplacement when an acid reactts with a base to form salt and water






15. The conversion of liquid into a gas






16. The transition from a gas into a solid






17. An atom that has an electrical charge






18. The process in which a solid can become a gas - like dry ice






19. The chemical potential for hydrogen - which determines whether or not a chemical is an acid or base






20. When two different substances combine to form a new substance or when a substance breaks down to form two different substance.






21. Metals that have low melting points






22. The decay of a nuclei which results in the emission of certain particlces






23. The different forms of an electron based on their neutrons






24. The size of an atom that decreases across a period. Within the group - it increases from top to bottom






25. The process of balancing chemical equations






26. Negative charged ions






27. A chemical bond in which two atoms share electrons like H2.






28. Chemicals like sodium that react with water to make alkaline solutions. Part of Group IA. They easily lose their valence electrons to become +1






29. Organic compounds that contain nitrogen - including protein






30. Hydrocarbons that involve carbon - carbon double bonds






31. Sodium






32. The number of protons/electrons within an atom






33. Metals that conduct electricity






34. Hydrochloric acid






35. The smallest form of a particle






36. Radioactive decay that leads to the emission of gamma particles






37. Small component of an atom that has no electrical charge






38. Measures of an attraction that an atom has ffor electrons in a chemical bond






39. When a compound breaks down into two or more substances by heating - like the break down of mercury oxide






40. When elements from two different compounds didsplace each other to form new compounds - like when solutions of CaCl and HgNi combine to form insoluble HgCl and CaNi






41. Move around the nucleus at the speed of light and have a negative charge






42. Metals mostly found in the middle of the table that are small and shiny. They are hard and have high melting and boiling points






43. The degree that two liquids can mix together






44. The energy required to completely remove an electron from an atom or an ion to make it ositive. the energy increases from left to right as the atomic radius diecreases






45. 1.66 x 10^-24 g






46. Occurs when one compound is replaced by an atom of another element like zinc metal






47. Substances that create hydroxide ions - have a pH level higher than 7 - and can conduct electricity






48. Hydrocarbons that include carbon - carbon triple bonds






49. Positive charged ions






50. Energy released when an electron is added to a gaseous atom
