WebAvogadro's law can be used to calculate the volumes of gases involved in reactions. Using Avogadro's law. Hydrogen reacts with chlorine to form hydrogen chloride: H 2 (g) + Cl 2 … WebGay-Lussac's law usually refers to Joseph-Louis Gay-Lussac's law of combining volumes of gases, discovered in 1808 and published in 1809. It sometimes refers to the proportionality of the volume of a gas to its absolute temperature at constant pressure. This law was published by Gay-Lussac in 1802, and in the article in which he described his work he … danby wiske yorkshire england

WebVolumes of gases. Avogadro suggested that ‘equal volumes of gases contain the same number of molecules’ (also called Avogadro’s hypothesis) At room temperature (20 degrees Celsius) and pressure (1 atm) one mole of any gas has a volume of 24.0 dm 3 ; This molar gas volume of 24.0 dm 3 mol-1 can be used to find: WebThe rate of decomposition of aqueous hydrogen peroxide, H 2 O 2 , is increased by an enzyme. 2 H 2 O 2 → 2 H 2 O + O 2 The rate of reaction is found by measuring the volume of oxygen gas given off as the reaction proceeds. The results are shown on the graph. WebIn this first video on gas volumes, we look at how to calculate the volume of a gas from Shop the Freesciencelessons store bird stained glass suncatcher
