WebThe Law of Combining Volumes enables us to figure out the ratios based on the stoichiometric coefficient. For example given the reaction 2H 2 +O 2 →2H 2 O; 2 volumes of hydrogen are reacting with 1 volume of oxygen to produce 2 volumes of water. In most cases, we use the same when determining the number of moles. WebThe law of combining volumes is also known as Gay-Lussac's law, as Gay-Lussac described how the pressure of enclosed gas is directly proportional to its temperature circa 1808. …
Web(a) Gay Lussac’s Law of Combining Volumes states that when gases react, they do so in volumes which bear a simple ratio to one another, and to the volume of the product (s) … WebNov 30, 2024 · Gay-Lussac’s law of combining volumes (1808) stated that when two gases react, the volumes of the reactants and products—if gases—are in whole number ratios. This law tended to support Dalton’s atomic theory, but Dalton rejected Gay-Lussac’s work. Avogadro, however, saw it as the key to a better understanding of molecular constituency.
