# 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?

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.

Please post the answers soon! Thanks for the interesting questions! · 2 years, 10 months ago

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. · 2 years, 10 months ago

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. · 2 years, 10 months ago

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. · 2 years, 10 months ago

could you explain ... i don't get it ! · 2 years, 8 months ago

Its because the pressure in the tank is high whereas the pressure in chamber is low · 2 years, 9 months ago

3) Flame is a region of burning of vapours and gases where heat and light are produced. · 2 years, 10 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.

For 2 Isnt NaCL salt? · 2 years, 10 months ago

Yes, common salt. However, the NaCl mentioned is not the commercial or iodized salt, but rather the purest forms of the salt. · 2 years, 10 months ago

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 :) · 2 years, 10 months ago

It seems like the only way, because the ions would form perfect cubes · 2 years, 10 months ago
