What substances, when burned, produce smoke? What substance burns without producing smoke? How can I find this information quickly?
Hehe, these days people ask questions and always demand standards, sources, and so on.... First, how to understand the character for “smoke”. Should it be temporarily understood here as “the gases produced when matter burns”? Hehe, looking it up on Baidu reveals many more meanings: lol
Smoke are unburned solid particles present in the flame due to incomplete combustion; what we see when we observe it is smoke. Certain fuels do not produce unburned solid particulate matter during combustion; even in the case of incomplete combustion, no smoke is visible. Such as hydrogen burning in a low-oxygen environment.
Check whether the combustion products are entirely gas or contain some solids; for example, when metals and certain non-metals burn and their oxides remain in solid form, smoke is produced, while the combustion of organic materials may result in carbon black due to incomplete burning
Smoke is what the expert upstairs mentioned – incomplete reactions or particles present in the reacting substances. To determine this, one needs to look at the chemical equation and the possible products. The combustion of carbon-containing organic compounds always produces smoke under various conditions; likewise, when solids burn, the vaporized condensates are also in the form of particles. In some cases, no smoke is produced, such as when dry hydrogen burns in chlorine, or when hydrogen burns in air or oxygen.
