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 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






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






3. The number of protons/electrons within an atom






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






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






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






7. The degree that two liquids can mix together






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






9. Components made up of a combination of atoms






10. Hydrochloric acid






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






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






13. 1.66 x 10^-24 g






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






15. The conversion of liquid into a gas






16. The transition from a gas into a solid






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






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






19. An atom that has an electrical charge






20. The outer electron in a shell






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






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






23. Ammonia






24. 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






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






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






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






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






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






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






31. Metals that conduct electricity






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






33. Hydrocarbons that include carbon - carbon triple bonds






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






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






36. Positive charged ions






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






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






39. The process of balancing chemical equations






40. Sodium






41. The conversion of a gas back into a liquid






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






43. Hydrocarbons that involve carbon - carbon double bonds






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






45. Metals that have low melting points






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






47. Radioactive decay in which half of a sample decays






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






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






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