Well, let's see . . . -- Sodium is a poisonous, corrosive metal, that's a waxy solid at room temperature. -- Chlorine is a poisonous halogen that's a gas at room temperature. When sodium and chlorine chemically combine, they form sodium chloride, which is table salt. -- Hydrogen is a gas at room temperature, and forms an explosive mixture with air. -- Oxygen is a gas at room temperature, we breathe it, and many thousands of other substances will burn in it. When hydrogen and oxygen chemically combine, they form dihydrogen oxide, which is water. Nope. Don't think so.
