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. Ammonia






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






3. 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






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






5. Metals that have low melting points






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






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






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






9. Hydrocarbons that involve carbon - carbon double bonds






10. 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






11. The transition from a gas into a solid






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






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






14. 1.66 x 10^-24 g






15. Hydrocarbons that include carbon - carbon triple bonds






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 conversion of liquid into a gas






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






19. Radioactive decay in which half of a sample decays






20. Anything that has mass and takes up space






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






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






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






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






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






26. An atom that has an electrical charge






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






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






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






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






31. The process of balancing chemical equations






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






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






34. The number of protons/electrons within an atom






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






36. Positive charged ions






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






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






39. The outer electron in a shell






40. The conversion of a gas back into a liquid






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






42. Organic compounds that contain nitrogen - including protein






43. Metals that conduct electricity






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






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






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






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






48. Components made up of a combination of atoms






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






50. 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
