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

6. 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






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






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






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






10. 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






11. The degree that two liquids can mix together






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






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






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






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






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






17. 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






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






19. Metals that conduct electricity






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






21. The conversion of a gas back into a liquid






22. Hydrochloric acid






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






24. The transition from a gas into a solid






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






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

36. Ammonia






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






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






39. Metals that have low melting points






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






41. 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






42. Organic compounds that contain nitrogen - including protein






43. Sodium






44. Hydrocarbons that include carbon - carbon triple bonds






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

47. Anything that has mass and takes up space






48. Components made up of a combination of atoms






49. The process of balancing chemical equations






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