Need help with chemistry scavenger hunt

[ilovemydog]

I have found about half of these and I would greatly appreciate help...thanks for your help in advance.

 

1. Two liquids demonstrating the Law of Multiple Proportions.

5. Compound formed by an alkali and a halogen.

12. Solution of an isomer of CH3-CH2-CH2OH.

14. Ternary compound of an alkaline earth metal.

16. Salt produced by mixing one mole of NaOH and one mole of H2CO3.

17. Glass container with metal that can form amalgams.

18. Any organic compound famous for its "fruity" smell (need chemical name).

20. Emulsifying agent

25. Ionic sunstance whose lattice energy is greater than its hydration energy.

26. Something that would lower the freezing point of water to -3.7 Celsius if one mole were placed in 1000g of water.

27. An element whose common oxidation numbers in compounds are +2 and +3.

28. A metal whose +2 ions form blue aqueous solutions.

16. Salt produced by mixing one mole of NaOH and one mole of H2CO3.

HX + BOH -> H20 + BX

BX is the salt

18. Any organic compound famous for its "fruity" smell (need chemical name).

look up some esters

 

20. Emulsifying agent

AKA soap. Look up some saponification reactions.

 

26. Something that would lower the freezing point of water to -3.7 Celsius if one mole were placed in 1000g of water.

salts lower the freezing point of water.

 

27. An element whose common oxidation numbers in compounds are +2 and +3.

Look this up on a periodic table

28. A metal whose +2 ions form blue aqueous solutions.

 

Periodic table + material safety data sheet should have this info...

 

 

Is this homework, btw?

[Darkblade48]

I have found about half of these and I would greatly appreciate help...thanks for your help in advance.

5. Compound formed by an alkali and a halogen.

If you mean alkali metal, then look no further than your kitchen for a compound that is formed between an alkali metal and a halogen.

 

12. Solution of an isomer of CH3-CH2-CH2OH.

Try drawing the molecule out, and placing the OH in various locations

 

25. Ionic sunstance whose lattice energy is greater than its hydration energy.

Look for compounds that, when added to water, cool down the solution

 

To ecoli: IMO, it sure seems like homework...

[ilovemydog]

yea this is a homework/test...its 1/3 of our grade...i might have more soon tyvm

[ilovemydog]

and another thing...i am not very good in chemistry so if you would please provide the answers instead of hints

[ecoli]

and another thing...i am not very good in chemistry so if you would please provide the answers instead of hints

 

If we give you answers, you won't learn how to figure things out for yourself. The hints are more than enough to lead you to the correct answers.

 

 

Thread moved to homework help.

[ilovemydog]

ok thanks for the help...i might have more later

[YT2095]

a simple Mercury thermometer.

 

Iron.

 

Copper is another answer.

 

there`s 3 answer now match them to the numbers

[John Cuthber]

Here's another 3 to help you with your "clean sweep"; again, all you need to do is work out which is which.

Bleach

Hydrogen peroxide solution

Soap

[ilovemydog]

can you please tell me if this is correct...i have come to the conclusion that

1. water and hydrogen peroxide

5. table salt

12. rubbing alcohol????

14. *still can't figure out*

 

16. baking soda?

17. Mercury thermometer

18. nail polish remover or any fruit?

20. soap?

25. *lost beyond belief*

27. Iron

28. Copper?

[ilovemydog]

Here's more...

30. An ethyl alcohol solution of 4-hydroxy-3-methoxy-benzaldehyde

31. A solution that is about 20 molal.

33. A slightly polar nonelectrolyte.

37. Compound of halogen other than chlorine.

38. Transition element that does not usually form colored compounds.

39. Salt of H2C4H4O6

40. Liquid that experiences abnormal behavior when it solidifies.

[YT2095]

sodium acetate (super saturated)

teflon

zinc

 

are a few for your latest list.

[John Cuthber]

Given that the answer to 40 is a fairly common liquid, is it really true to say that it has abnormal behaviour?

Normally I sugest Google but for #14 I'd try wiki and see what it can tell you about ternary compounds.

I'm a long way from convinced about your answer to #5

Someone said

"If you mean alkali metal, then look no further than your kitchen for a compound that is formed between an alkali metal and a halogen.". What about if you don't mean that?

[ilovemydog]

ok thanks for the help but i have no idea what you mean by you don't know if #5 is right and the question about 20 molal has completely blown my mind...and there is about 100 of these but i have found out about 45-50.

[ilovemydog]

hey guys could 30 be vanillin?

[ilovemydog]

ternary compounds isn't on wiki..........

[YT2095]

vanilla essence (not the extract) it`s the cheap stuff you want.

 

I too ,was wondering what would constitute "Abnormal" also, I think you have plenty room for scope on this one.

[ilovemydog]

41. Solution which produces hydrogen and chlorine gases when electrolyzed and yields a very basic end product.

45. Substance that boils 70 Celsius at 30 kPa.

51. Starch, acid salt, and sodium hydrogen carbonate.

54. Unstable acid (not explosive)

56. Any ionic flouride.

36. Salt produced by mixing two moles of NaOH and one mole of H2CO3.

[YT2095]

Baking powder is one of them, I`m beginning to wonder, are you guys trying to bake a Cake or something?

[John Cuthber]

"ternary compounds isn't on wiki.........."

How hard did you look?

http://en.wikipedia.org/wiki/Ternary_compound

 

"Baking powder is one of them, I`m beginning to wonder, are you guys trying to bake a Cake or something?"

I hope they don't plan to put any ionic fluorides in it.

I also think they might be asking about the reaction product(s) of chlorine (a halogen) and sodium hydroxide (an alkali, rather than a metal)

[YT2095]

well, after eating Cake it`s policy to brush ones teeth, Oooops, there`s Another Hint

[ilovemydog]

2.A heterogeneous mixture

3.A homogenous mixture

7.A substance which has a volume of 1 cm3

8.An edible example of a physical change

15.A substance with a density more than one

21. A substance that proves the equilibrium effect.

22. An element with more than 4 oxidation numbers.

[YT2095]

I`m getting a little concerned here, forget the cake, you guys planning on making a Quantum Singularity or something!?

[Alarius]

Wow this is sad how hard are you trying??

14 Hard so I give, get a piece of Chalk

16 correct

17 correct or a tooth filling in a glass bottle

18 dont bring a fruit, get flavoring, best is to bring Banana flavoring

20 close

25 just google it

27 correct

28 Correct

 

 

You also said

30. An ethyl alcohol solution of 4-hydroxy-3-methoxy-benzaldehyde

31. A solution that is about 20 molal.

33. A slightly polar nonelectrolyte.

37. Compound of halogen other than chlorine.

39. Salt of H2C4H4O6

40. Liquid that experiences abnormal behavior when it solidifies.

....................

30 Not to be mean but did you even try just typing that into google?

31 This one is hard. Fudge

33 yet again google man

37 A joke right? Google is your friend

38 Guess what ima say

39 See previous

40 Ok since a lot of people are confused i will explain. When something solidifies what does it do? contract. So abnormal behavior would be action other than contraction. Look no further than your ICE box.

 

Yet again you said

41. Solution which produces hydrogen and chlorine gases when electrolyzed and yields a very basic end product.

45. Substance that boils 70 Celsius at 30 kPa.

51. Starch, acid salt, and sodium hydrogen carbonate.

54. Unstable acid (not explosive)

56. Any ionic flouride.

36. Salt produced by mixing two moles of NaOH and one mole of H2CO3.

...........................

41 google (hint very basic means high pH, not simple)

45 hardish, water

51 google

54 google

56 Toothpaste

36 google

 

Once more

2.A heterogeneous mixture

3.A homogenous mixture

7.A substance which has a volume of 1 cm3

8.An edible example of a physical change

15.A substance with a density more than one

21. A substance that proves the equilibrium effect.

22. An element with more than 4 oxidation numbers.

........................

2,3 Look up the definition of the words

7 google it (hint: same as 45)

8 what is a physical change? (try like a cube of ice)

15 anything that will float above water

21 google

22 Nitrogen for one, but you arnt able to bring it to class, guess what google

 

 

Word of note: You need to embrace google as your friend, for most of these you can straight type the question into google and blam get an answer.

Also 8 of em are water or some form of water.

 

P.S. ha hows that for a first post
