Question

1. drag and drop the descriptions with the laws.

proposed by joseph proust and known as the law of constant composition
proposed by antoine lavoisier and commonly applied to chemical reactions
proposed by jeremias richter and focused on the ratios of two different elements combining with a third element
proposed by john dalton and indicates small whole numbers are formed from the ratios of combined elements

Explanation:

• The law of definite proportions (also known as the law of constant composition) was proposed by Joseph Proust. It states that a given chemical compound always contains its component elements in fixed ratio (by mass) and does not depend on its source and method of preparation.
• The law of conservation of mass was proposed by Antoine Lavoisier. It states that mass is neither created nor destroyed in a chemical reaction.
• The law of reciprocal proportions was proposed by Jeremias Richter. It states that if two different elements combine separately with a fixed mass of a third element, the ratio of the masses in which they do so are either the same as or a simple multiple of the ratio of the masses in which they combine with each other.
• The law of multiple proportions was proposed by John Dalton. It states that if two elements form more than one compound between them, then the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers.

Answer:

• proposed by Joseph Proust and known as the law of constant composition: law of definite proportions
• proposed by Antoine Lavoisier and commonly applied to chemical reactions: law of conservation of mass
• proposed by Jeremias Richter and focused on the ratios of two different elements combining with a third element: law of reciprocal proportions
• proposed by John Dalton and indicates small whole numbers are formed from the ratios of combined elements: law of multiple proportions
