Subject : engineering
Instructions:
  • Answer 40 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. The heat of reaction when water is assumed to remain in a vapor state; also called the net heat of combustion






2. At standard STP (corresponding to __ degrees celsius and __ atm) - 1 mole of an ideal gas occupies ___ L and contains ___ molecules.






3. Ortho: side by side - meta: one point away - forms an M - para: opposite each other






4. E=hv=(hc)/wavelength where: E=energy of a photon (J) h=planck's constant (6.6x10^-34 Js) v=frequency (hertz - ie. cycles per second) c=speed of light (3.0x10^8 m/s) gamma=wavelength (m)






5. Organic matter - silt - clay - sand






6. The flow of electrons goes to...






7. When change in H (enthalpy) is positive - heat is _____________ and the reaction is said to be _____________






8. Mass (g)/molecular weight






9. Atoms containing the same number of protons but differing amounts of neutrons are __________ of each other






10. If we divide the mass of a substance by its molecular weight - the result is the mass expressed in ________.






11. Groups linked by straight or branched carbon chains






12. Inorganic






13. Electrons are free to cycle around arrangements of atoms which are alternatively single- and double- bonded to one another. These bonds may be seen as a hybrid of a single bond and a double bond - each bond in the ring identical to every other






14. 1 atm and 298 K (kj/mol)






15. The number of moles of substance per liter of solution






16. The process of going from one phase to another






17. The mass of the atom measured in atomic mass units (1 proton=1 amu)






18. 1 mole of a substance dissolved into enough water to make the mixture have a volume of 1 L.






19. Vector sum of all bond dipoles in a structure






20. Unsaturated - has double bonds!






21. All single bonds






22. The more molecules of benzene - the more hydrophilic/hydrophobic the compound






23. Organic - carbonates (they're inorganic)






24. For a photon to be able to cause photolysis - it must have at least as much energy as...






25. Photochemical reaction; photochemical dissociation; or simply photolysis






26. Wavelength </= hc/E






27. Natural waste






28. First balance the chemical reaction - then for each species multiply the number of moles by the standard enthalpy to find total enthalpy






29. 6.02x10^23 molecules






30. The sum of the atomic weight of all the constituent atoms






31. H=U+PV; H2-H1=change in H=Q






32. Circle (hexagonal if we'z gon get technical hurr) alkenes with double bonds at every other joint.






33. The heat released when water condenses to liquid form - also known as the gross heat of combustion






34. >100 -000; there is no natural decay cycle for them

35. Number of protons in the nucleus






36. Ring structures: - enes (double bonds); - anes (single bonds)






37. Molecules cannot store up energy from a series of photon encounters (waiting until enough energy is accumulated to cause photolysis...






38. Change in enthalpy (H2-H1); the sum of the enthalpies of the reaction products minus the sum of the enthalpies of the reactants






39. Benzene; graphite






40. Energy/mole
