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






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






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






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






5. 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






6. Anything that has mass and takes up space






7. The process of balancing chemical equations






8. Hydrocarbons that include carbon - carbon triple bonds






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






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






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






12. The transition from a gas into a solid






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






14. Sodium






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






16. 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






17. The outer electron in a shell






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






19. The degree that two liquids can mix together






20. 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






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






22. Water






23. Metals that conduct electricity






24. Hydrochloric acid






25. Components made up of a combination of atoms






26. The number of protons/electrons within an atom






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






28. Radioactive decay in which half of a sample decays






29. 1.66 x 10^-24 g






30. 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






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






32. The conversion of a gas back into a liquid






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






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






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






36. Positive charged ions






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






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






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






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






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






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






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






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






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






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






47. Organic compounds that contain nitrogen - including protein






48. Hydrocarbons that involve carbon - carbon double bonds






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






50. An atom that has an electrical charge
