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






2. The conversion of liquid into a gas






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






4. Components made up of a combination of atoms






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






6. 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






7. Hydrocarbons that include carbon - carbon triple bonds






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






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






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






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






12. Negative charged ions






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






14. Hydrocarbons that involve carbon - carbon double bonds






15. The conversion of a gas back into a liquid






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






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






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






19. The process of balancing chemical equations






20. Ammonia






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






22. Metals that have low melting points






23. 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






24. Sodium






25. Hydrochloric acid






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






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






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






30. Metals that conduct electricity






31. Water






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






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






34. An atom that has an electrical charge






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






36. Organic compounds that contain nitrogen - including protein






37. Radioactive decay in which half of a sample decays






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






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






40. 1.66 x 10^-24 g






41. Hydrocarbons that have single bonds with a prefix to show the number of carbon atoms - like methane - ethane - propane - butane - pentane - and hexane






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






43. When two reactants form one product - like sulfur dioxide by burning sulfur in the air






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






45. Anything that has mass and takes up space






46. The outer electron in a shell






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






48. The smallest form of a particle






49. The degree that two liquids can mix together






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