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






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






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






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

26. The transition from a gas into a solid






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






28. 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

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






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






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






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






34. Hydrocarbons that include carbon - carbon triple bonds






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






36. The conversion of a gas back into a liquid






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






38. Negative charged ions






39. The outer electron in a shell






40. 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






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






42. Components made up of a combination of atoms






43. Metals that conduct electricity






44. The smallest form of a particle






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. Hydrocarbons that involve carbon - carbon double bonds






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






48. Anything that has mass and takes up space






49. Organic compounds that contain nitrogen - including protein
