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 transition from a gas into a solid






2. Anything that has mass and takes up space






3. Water






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






5. Ammonia






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






7. 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






8. The conversion of liquid into a gas






9. The degree that two liquids can mix together






10. Metals that conduct electricity






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






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






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






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






15. Metals that have low melting points






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






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






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






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






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






21. Positive charged ions






22. Radioactive decay in which half of a sample decays






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






24. 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






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






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






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






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






29. Organic compounds that contain nitrogen - including protein






30. Negative charged ions






31. 1.66 x 10^-24 g






32. Hydrocarbons that involve carbon - carbon double bonds






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






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






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






36. 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






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






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






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






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






41. The process of balancing chemical equations






42. The smallest form of a particle






43. The outer electron in a shell






44. Hydrochloric acid






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






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






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






48. An atom that has an electrical charge






49. The number of protons/electrons within an atom






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