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. Water






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






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






4. Metals that conduct electricity






5. Anything that has mass and takes up space






6. Ammonia






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






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






9. 1.66 x 10^-24 g






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






11. 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






12. Negative charged ions






13. Hydrochloric acid






14. Hydrocarbons that involve carbon - carbon double bonds






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






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






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






18. The smallest form of a particle






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






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






21. Organic compounds that contain nitrogen - including protein






22. The transition from a gas into a solid






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






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






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






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






27. The process of balancing chemical equations






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






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






30. 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






31. The conversion of a gas back into a liquid






32. 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






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






34. Radioactive decay in which half of a sample decays

37. Positive charged ions






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






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






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






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

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






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






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






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






48. Sodium






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






50. The degree that two liquids can mix together
