Laws of chemical conbination?
The laws of chemical combination are fundamental principles that govern the relationships between the quantities of reactants and products in a chemical reaction. The three main laws are the law of conservation of mass, the law of definite proportions, and the law of multiple proportions. The law of conservation of mass states that mass is conserved in a chemical reaction, meaning that the total mass of the reactants is equal to the total mass of the products. The law of definite proportions states that a compound always contains the same proportions of elements by mass. The law of multiple proportions states that when two elements combine to form multiple compounds, the mass ratios of the elements in the compounds are always in whole-number ratios.
How are experimental data used to show that compound obeys the law of definite proportions?
Experimental data can be used to show that a compound obeys the law of definite proportions by determining the mass ratios of elements in the compound. By analyzing the masses of elements present in different samples of the compound and comparing them, one can show that the elements combine in specific, fixed ratios according to the law of definite proportions.
Is it true that a chemical has a definite composition?
Yes, after the Law of definite proportions; but now it is clear that this law is not applicable to all known chemical compounds.
Why is the law of definite proportion important.?
In chemistry, the law of definite proportions, sometimes called Proust's Law, states that a chemical compound always contains exactly the same proportion of elements by mass. An equivalent statement is the law of constant composition, which states that all samples of a given chemical compound have the same elemental composition by mass. For example, oxygen makes up about 8/9 of the mass of any sample of pure water, while hydrogen makes up the remaining 1/9 of the mass. Along with the law of multiple proportions, the law of definite proportions forms the basis of stoichiometry.
Does The Law of Definite Proportions state that substances combine in predictable proportions and that excess reactants remain unchanged?
The Law of Definite Proportions states that chemical compounds always contain the same elements in the same proportions by mass. It does not specifically address what happens to excess reactants in a chemical reaction.
1 Differentiate between The Law of Definite Proportions and The Law of Multiple Proportions?
Well definite is broad and multiple is more exact that's about what I can think of
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.
Who developed the multiple proportions law?
The Law of Multiple Proportions was developed by John Dalton based on the Law of Definite Proportions, was part of what laid the groundwork for his atomic theory, and for the basis of chemical formulas for compounds.English chemist John Dalton
When was the law of definite proportions developed?
The law of definite proportions was developed by Joseph Proust in 1806.
Which of Dalton's four principles support law of definite proportions?
Dalton\'s principle of compounds supports the law of definite proportions.
'Law of multiple Proportion was discovered by whom?
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.
What year did Joseph Proust make the law of definite proportions?
In was in 1799 that Joseph Proust discovered the law of definite proportions, or Proust's Law. Proust was a French chemist.
What is the name of the chemical law?
For example the law of definite proportions.

Who developed the law of Definite Proportions?
Joseph Proust
Who made the law of multiple proportions?
The law of multiple proportions was proposed by John Dalton in 1804; today this law has not a general validity.
State the law of definite proportions?
The law of definite proportions states that a compound always contains the same elements in the same proportion by mass, regardless of the source of the compound. This means that for a given compound, the ratio of the masses of the elements is always constant.
