Which law of chemical combination states that when two elements combine to form more than one compound, the different masses of one element that combine with a fixed mass of the other element are in a ratio of small whole numbers?

💡 Solution & Explanation

John Dalton's law of multiple proportions states that if two elements form multiple compounds together, the mass ratios of one element combining with a fixed mass of the other form simple numerical ratios. The law of conservation of mass asserts that matter is neither created nor destroyed during chemical reactions. The law of definite proportions specifies that a given chemical compound always contains its component elements in fixed mass ratios. Gay-Lussac's law relates gaseous reaction volumes under constant conditions.
