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. Distilled water - which has the ph level of 7






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






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






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






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






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






7. The process of balancing chemical equations






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






9. Hydrochloric acid






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






11. Water






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






13. Positive charged ions






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






15. Metals that have low melting points






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






17. Hydrocarbons that involve carbon - carbon double bonds

31. Ammonia






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






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






34. 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






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






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






37. 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






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






39. An atom that has an electrical charge
