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






2. Anything that has mass and takes up space






3. Positive charged ions






4. Hydrocarbons that include carbon - carbon triple bonds






5. The smallest form of a particle






6. Components made up of a combination of atoms






7. 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






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






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






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






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






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






14. Metals that have low melting points






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






16. Hydrocarbons that involve carbon - carbon double bonds






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






18. 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






19. Metals that conduct electricity






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






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






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






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






24. 1.66 x 10^-24 g






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






26. Ammonia






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






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






29. Hydrochloric acid






30. An atom that has an electrical charge






31. The number of protons/electrons within an atom






32. The outer electron in a shell






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






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






35. The conversion of liquid into a gas






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






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






38. 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






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






40. The transition from a gas into a solid






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






42. Water






43. The process of balancing chemical equations






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






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






46. Negative charged ions






47. Organic compounds that contain nitrogen - including protein






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






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






50. The degree that two liquids can mix together
