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






2. The process of balancing chemical equations






3. The conversion of a gas back into a liquid






4. Organic compounds that contain nitrogen - including protein






5. Hydrocarbons that involve carbon - carbon double bonds






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






7. 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






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






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






10. Hydrochloric acid






11. The size of an atom that decreases across a period. Within the group - it increases from top to bottom






12. The transition from a gas into a solid






13. Hydrocarbons that include carbon - carbon triple bonds






14. The smallest form of a particle






15. 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






16. Sodium






17. The degree that two liquids can mix together






18. An atom that has an electrical charge






19. 1.66 x 10^-24 g






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






21. The number of protons/electrons within an atom






22. The outer electron in a shell






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






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






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






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






27. 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






28. Components made up of a combination of atoms






29. Metals that have low melting points






30. Water






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






32. 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






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






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






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






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






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






38. Radioactive decay in which half of a sample decays






39. Negative charged ions






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






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






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






43. The conversion of liquid into a gas






44. Anything that has mass and takes up space






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






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






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






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






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






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