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






3. 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






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






5. Components made up of a combination of atoms






6. 1.66 x 10^-24 g






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






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






9. Anything that has mass and takes up space






10. Radioactive decay in which half of a sample decays






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






12. 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






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






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






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






16. Negative charged ions






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






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






19. The number of protons/electrons within an atom






20. Metals that conduct electricity






21. Hydrochloric acid






22. Metals that have low melting points






23. Water






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






25. 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






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






27. The process of balancing chemical equations






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






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






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






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






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






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






35. Organic compounds that contain nitrogen - including protein






36. Hydrocarbons that include carbon - carbon triple bonds






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






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






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






40. Ammonia






41. An atom that has an electrical charge






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






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






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






45. 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






46. The degree that two liquids can mix together






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






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






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






50. The conversion of liquid into a gas
