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. Organic compounds that contain nitrogen - including protein






2. Metals like calcium that produce alkaline solutions when combined with water. Part of Group IIA. Have two electrons in their outer shells






3. The transition from a gas into a solid






4. Components made up of a combination of atoms






5. 1.66 x 10^-24 g






6. Negative charged ions






7. The process of balancing chemical equations






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






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






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






11. Radioactive decay that leads to an emission of Helium -4 ion






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






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






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






15. The conversion of a gas back into a liquid






16. Metals that have low melting points






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






18. The bond formed when an anion and a cation unite and form a chemical reaction






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

21. Small component of an atom that has a positive electrical charge






22. The degree that two liquids can mix together






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






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






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






26. Ammonia






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






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






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






30. 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






31. The outer electron in a shell






32. Hydrocarbons that involve carbon - carbon double bonds






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






34. An atom that has an electrical charge






35. The conversion of liquid into a gas






36. Part of group VIIA and are highly reactive nonmetals. They have seven valence electrons and range from bein ggaseous to solids. Includes fluoride - chloride - and iodine






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






38. 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






39. 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






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






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

43. Sodium






44. Hydrochloric acid






45. Metals that have a variety of property that include carbon - nitrogen and oxygen vital to the earth






46. Positive charged ions






47. Water






48. Hydrocarbons that include carbon - carbon triple bonds






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






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