38. A nonmetal. Define nonmetal. Common name and chemical formula required.

39. An electrolyte. Define electrolyte. Common name, chemical name, chemical formula required.

40. Something containing L-carvone or D-carvone. Identify which one you have. What characteristic does it impart to the substance which distinguishes it from the item you did not bring in.

41. The solid product of the reaction between aqueous solutions of calcium chloride and sodium carbonate. Balanced equation, chemical formula and common name required.

42. An aqueous solution of a nonelectrolyte. Identify the solute and solvent by common name.

43. A molecule with bonding that follows the octet rule. Common name, chemical name, chemical formula required.

47. A polymer of vinyl chloride. Define polymer. Identify the specific subunits of this polymer. Common name required.

48. An oxide of an element. Common name, chemical name, chemical formula required.

49. The salt produced when magnesium hydroxide reacts with sulfuric acid. Balanced equation, chemical formula, chemical name, and common name required.

50. The amount of NaCl produced from 10.0 g of sodium hydrogen carbonate reacting with an excess of hydrochloric acid. Assume 75 % yield. Balanced equation and calculations required. (no work, no credit, no kidding)

It looks like you did the first 18 and gave up when you couldn't do number 19. I would skip it and try some of the later ones if I were you.

19. I believe rust is one such product.

20. Table salt and drinking alcohol (ethanol).

21. Vinegar is correct.

22. I am not sure, but I think this is glass and/or sand.

23. Water is correct.

24. Silicon.

25. Table salt.

There's a few for you. Try looking for key terms on Google. It should give you most of these answers.

did you ever find the other answers for this scavenger hunt?
