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






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






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






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






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






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






7. Radioactive decay in which half of a sample decays






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






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






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






11. A chemical that is sour and stings and receives positive charged atoms when they are dissolved in water






12. 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






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






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






15. Ammonia






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






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






18. Negative charged ions






19. 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






20. Components made up of a combination of atoms






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






22. An atom that has an electrical charge






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






24. The outer electron in a shell






25. The degree that two liquids can mix together






26. Anything that has mass and takes up space






27. Hydrocarbons that include carbon - carbon triple bonds






28. Hydrochloric acid






29. Metals that have low melting points






30. The process of balancing chemical equations






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






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






33. 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






34. The transition from a gas into a solid






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






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






37. 1.66 x 10^-24 g






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






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






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






41. Water






42. Organic compounds that contain nitrogen - including protein






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






44. Sodium






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






46. The conversion of a gas back into a liquid






47. Hydrocarbons that involve carbon - carbon double bonds






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






49. 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






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