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. Anything that has mass and takes up space






2. Components made up of a combination of atoms






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






4. An atom that has an electrical charge






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






6. The transition from a gas into a solid






7. Ammonia






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






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






10. The conversion of liquid into a gas






11. The number of protons/electrons within an atom






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






13. Organic compounds that contain nitrogen - including protein






14. Radioactive decay in which half of a sample decays






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






16. 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






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






18. Hydrocarbons that involve carbon - carbon double bonds






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






20. Hydrochloric acid

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






30. The degree that two liquids can mix together






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






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






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






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






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






36. The process of balancing chemical equations






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






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. Sodium






40. The outer electron in a shell






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






42. 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
