Which of the following pairs of compounds can be used to illustrate the law of multiple proportions

Which one of the following pairs of compounds illustrate the law of multiple proportions?

Carbon and oxygen combine to form two oxides, carbon monoxide and carbon dioxide in which the ratio of the weights of carbon and oxygen is respectively 12:16 and 12:32.

Which of the following compounds can not demonstrate the law of multiple proportion?

To demonstrate this law, two/more compounds of common two elements are required. Hence, Na2S and NaF can’t demonstrate law of multiple proportions.

What is the law of multiple proportion explain with example?

This example illustrates the law of multiple proportions: Whenever the same two elements form more than one compound, the different masses of one element that combine with the same mass of the other element are in the ratio of small whole numbers. … Carbon can form two different compounds with oxygen.

What does the law of definite proportions apply to compounds?

The Law of Definite Proportions ensures that chemical compounds are always created using the same proportions, regardless of the amount of the compound which is being made.

Which one is the best example of law of conservation of mass?

The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases, equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.

Which of the following illustrates the law multiple proportions?

Answer. law of multiple proportions, states that when two elements combine to form more than one compound, the mass of one element, which combines with a fixed mass of the other element, will always be ratios of whole numbers.

Does no2 and n2o law of multiple proportions?

According to the law of multiple proportions, the mass of an element combined with the fixed mass of another element should have whole number ratios. … Because the ratio of the masses of oxygen turned out to be whole number ratios, then it shows that NO and NO2 follow the law of multiple proportions.

Can two elements form more than one compound?

The law of multiple proportions states that if two elements form more than one compound between them, the masses of one element combined with a fixed mass of the second element form in ratios of small integers. Consider two separate compounds are formed by only carbon and oxygen.

Who proposed the law of multiple proportion?

John Dalton

What is law of constant proportion Class 9?

The law of constant proportions states that chemical compounds are made up of elements that are present in a fixed ratio by mass. This implies that any pure sample of a compound, no matter the source, will always consist of the same elements that are present in the same ratio by mass.

Who discovered the law of constant composition?

Joseph Proust
