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.

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






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






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






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






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






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

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






31. Hydrochloric acid






32. Metals that have low melting points






33. 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






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






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

40. The process of balancing chemical equations






41. The conversion of liquid into a gas






42. The number of protons/electrons within an atom






43. Negative charged ions






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






45. 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






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






47. The outer electron in a shell






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






49. Hydrocarbons that involve carbon - carbon double bonds






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