Subject : engineering
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 condensation polymerization results with an ester bond between two reactants and this comes off as a result






2. Addition polymerization is commonly initiated by ___ - atoms that have an unpaired electron.

15. Cell found in the lining of the blood vessels that release heparin and are a part of the negative feedback system.
