Interesting Chemistry Questions

1) Why doesn't an Oxygen chamber explode whereas an oxygen tank explodes?

2) Is there any way to show that NaCl is Ionic in solid form?

3) What is the chemical definition of a flame?

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

1) Oxygen isn't a fuel, just an oxidizing agent (surprise!) that allows other fuels to burn. I have no idea about the reaction mechanism, which Wikipedia tells me involves a triplet oxygen species, something I have no clue about. Please feel free to enlighten me.

BTW, this question reminds me of another (trick) question I've read: you enter a room filled with methane gas, and strike a match? What happens? The answer is, of course, nothing, since oxygen isn't available to oxidize the fuel.

2) I suppose this is asking for a way to distinguish between a macromolecular covalent structure and an ionic lattice. The obvious way is to try and dissolve it in water (a polar solvent, as @Nanayaranaraknas Vahdam mentioned). If it dissolves, it's ionic. Beyond that, I'm not sure, unless maybe it involves cleaving the crystal in some manner to identify its geometry.

3) I'm not into definitions, but a flame is essentially composed of gas molecules which have high enough internal energy that they become ionized, forming a plasma and emitting photons. Again, I have no clue how this happens.

I have a definition for flame. Flame is the result of the rapid and highly exothermic combustion of gases in a small, restricted volume and area.

For the oxygen question, I believe that the amount of pressure in an oxygen tank is incredibly high, compared to an oxygen chamber. The tank consists of compressed gas, and the "explosion" is just the result of a sudden change in pressure. Oxygen itself does not combust.

For, NaCl, I know a way if it is dissolved in polar solvent. In the solid form if it forms a Face Centred Cubic crystal, without water of hydration, then it's ionic properties can be proven. It would require a lot of time though.

could you explain ... i don't get it !

Very interesting! I have been pondering on these questions for a long time.

Hi! I study a little Chemistry at High School; I have an idea for question no. 2.

Solid NaCl have a giant lattice structure of alternating Na+ and Cl- ions. So to show, simply mimic and draw the 3D version of the lattice of ions, I guess.

Is that what you're looking for? Hope I helped :)

It seems like the only way, because the ions would form perfect cubes

For 2 Isnt NaCL salt?

- 6 years, 9 months ago

Yes, common salt. However, the NaCl mentioned is not the commercial or iodized salt, but rather the purest forms of the salt.

WHAT IS THE IUPAC NAME OF KERESONE

- 6 years, 9 months ago

I think....the amount of pressure in oxygen tank is much greater as compared to oxygen chamber.which becomes the reason for explosion.

3) Flame is a region of burning of vapours and gases where heat and light are produced.

- 6 years, 9 months ago

Don't know

- 6 years, 8 months ago

Its because the pressure in the tank is high whereas the pressure in chamber is low

I constantly have problems with my chemistry homework. It is difficult for me. But I found a solution for myself. It is WoWgrade. Real professionals will help you with any question or homework of any complexity. Try it, maybe you will find an answer on your question there.
