Gases that are reactive
The noble gases are colorless, odorless, tasteless, and nonflammable under standard conditions. They were once labeled group 0 in the periodic table because it was believed they had a valence of zero, meaning their atoms cannot combine with those of other elements to form compounds. However, it was later discovered some do indeed form compounds, causing this label to fall into dis… WebJul 20, 2024 · Definition: law of combining volumes. When gases combine at constant temperature and pressure, the volumes involved are always in the ratio of simple whole numbers. Since the factor RT/P would be the same for all three gases, the volume of O 2 ( g) consumed must be half the volume of H 2 ( g) consumed. The volume of H 2 O ( g) …
