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. Organic compounds that contain nitrogen - including protein

40. The process in which a solid can become a gas - like dry ice






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






42. 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






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






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