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 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






2. Positive charged ions






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






4. 1.66 x 10^-24 g






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






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






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






8. 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






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






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 decay of a nuclei which results in the emission of certain particlces






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






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






14. Hydrochloric acid






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






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






17. Sodium






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






19. An atom that has an electrical charge






20. The conversion of liquid into a gas






21. Organic compounds that contain nitrogen - including protein






22. Metals that have low melting points






23. Negative charged ions






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






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






26. The number of protons/electrons within an atom






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






28. Metals that conduct electricity






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






30. Anything that has mass and takes up space






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






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






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






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






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






36. Hydrocarbons that involve carbon - carbon double bonds






37. Hydrocarbons that include carbon - carbon triple bonds






38. The degree that two liquids can mix together






39. The transition from a gas into a solid






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






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






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






43. Components made up of a combination of atoms






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






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






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






47. The conversion of a gas back into a liquid






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






49. Water






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