Is This a Physical or Chemical Property?

Question

Hydrogen sulfide is removed from the natural gas used to heat homes through a reaction with oxygen

Answer 1

2 H2S(g) + 3 O2(g) → 2 H2O(g) + 2 SO2(g)

notice that bonds are broken between hydrogen and sulfur and between oxygen and oxygen?

also notice that new bonds between H and O and between S and O are formed?

anytime bonds are broken or formed, the reaction is always a "chemical" reaction.

therefore this is a chemical change. and as a result, the property of H2S that allows it to be removed from natural gas via burning is a chemical property.

Answer 2

The reaction is Chemical but, as far as I am aware (having years of experience in the process), not with Oxygen.

H2S in the sweetening of Natural Gas is not removed by reaction with Oxygen.
It is removed by a high pressure Absorption Process using an absorbent like DEA (Diethanolamine) to absorb the H2S (and much of the CO2).
The Absorbent is recirculated via a 'Stripping' process which decreases pressure and increases temperature to remove the sour gases. The H2S may be sent to a Sulphur production unit or to a Flare system for disposal.
(By the way, H2S, CO2, H2O and H2O vapour are all removed before Natural Gas can be Liquefied to LNG. They would freeze up the tubes of the Cryogenic Process Plant).

(The Natural Gas, as a gas, is also lightly re-odourised with a sulphur mercaptan to allow detection should leakage occur).

Answer 3

Heat is the result of the chemical reaction between H2s and O2

Answer 4

Chemical reaction with oxygen is chemistry.

Answer 5

This is a chemical reaction. When you see reactions between elements, you know that it is a chemical reaction and not physical.

Answer 6

if there is a word reaction then its a chemical property

Answer 7

This is a chemical property.

Answer 8
