The law of multiple proportions was proposed by John Dalton in the early 19th century. It states that when elements combine to form compounds, the ratio of masses of one element that combines with a fixed mass of the other element can be expressed in small whole numbers.

If the following elements were to combine with each other choose which demonstrate the Law of Multiple Proportion. Select all that apply.?
Hydrogen and Oxygen Carbon and Oxygen Nitrogen and Oxygen The combination of Hydrogen and Oxygen demonstrates the Law of Multiple Proportion as they can form water in different proportions such as H2O or H2O2. Nitrogen and Oxygen can also exhibit the Law of Multiple Proportion in compounds like NO and NO2.
Does adding coefficients to a chemical equation disobey the law of definite proportion?
No, adding coefficients to a chemical equation does not disobey the law of definite proportion. The coefficients simply represent the relative number of moles of each substance involved in the reaction and do not alter the proportion of elements present in the compounds.
What is the law that states that a chemical compound always contains the same elements in exactly the same proportions by w eight and mass?
The law you are referring to is the Law of Definite Proportions. This law states that a chemical compound always contains the same elements in the same proportions by mass, regardless of the source of the compound.
What are the five laws of chemical combination?
Law of conservation of mass: Mass is conserved in a chemical reaction. Law of definite proportions: Chemical compounds always contain the same elements in the same proportion by mass. Law of multiple proportions: When two elements form more than one compound, the ratios of the masses of one element that combine with a fixed mass of the other element can be expressed in small whole numbers. Law of combining volumes: Gases react in simple numerical ratios of volumes. Avogadro's law: Equal volumes of gases at the same temperature and pressure contain the same number of molecules.
What are the three laws governing chemical reactions?
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. The law of definite proportions states that compounds always contain the same elements in the same proportion by mass. The law of multiple proportions states that when elements combine to form different compounds, the ratio of their masses follows simple whole-number ratios.

What law is described by the fact that the ratio of the mass of oxygen in carbon dioxide to the mass of oxygen in carbon monoxide?
law of multiple proportion
What is the fundamental law of proportion?
nothing
What is the law of multiple of proportion?
The law of multiple proportions states that when two elements combine to form two or more compounds, the mass of one element that combines with a given mass of the other is in the ratio of small whole numbers.According to the law of multiple proportions, if 2 elements were to join together for forming a compound, the weight of one element in relation to another is in a ratio. The ration is a small discrete number.
