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






3. Water






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






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






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






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






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






9. Ammonia






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






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






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






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






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






15. The smallest form of a particle






16. Sodium






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. Negative charged ions






19. The conversion of a gas back into a liquid






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






21. 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






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






23. The conversion of liquid into a gas






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






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






26. Metals that conduct electricity






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






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






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






30. Components made up of a combination of atoms






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






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






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






34. The number of protons/electrons within an atom






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






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






37. The degree that two liquids can mix together






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






39. 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






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






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






42. Hydrocarbons that involve carbon - carbon double bonds






43. Hydrochloric acid






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






45. 1.66 x 10^-24 g






46. The process of balancing chemical equations






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






48. Positive charged ions






49. Hydrocarbons that include carbon - carbon triple bonds






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