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 conversion of liquid into a gas






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






3. 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






4. The process of balancing chemical equations






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






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






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






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






9. Hydrochloric acid






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






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






12. Anything that has mass and takes up space






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






14. 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






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






16. Components made up of a combination of atoms






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






18. The degree that two liquids can mix together






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






20. The number of protons/electrons within an atom






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






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






23. 1.66 x 10^-24 g






24. Ammonia






25. Sodium






26. 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






27. The outer electron in a shell






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






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






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






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






32. Hydrocarbons that involve carbon - carbon double bonds






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






34. Metals that have low melting points






35. Radioactive decay in which half of a sample decays






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






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






38. Hydrocarbons that include carbon - carbon triple bonds






39. Metals that conduct electricity






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






41. Organic compounds that contain nitrogen - including protein






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






43. Positive charged ions






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






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






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






47. Water






48. 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






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






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