What kind of stoichiometry refers to the mass relationships of elements in compounds?
Mass stoichiometry refers to the study of the mass relationships of elements in compounds. It involves analyzing the stoichiometric coefficients in a balanced chemical equation to determine the relative masses of reactants and products. This helps in calculating the amount of reactants needed or products formed in a chemical reaction.
What law explains relationships between different chemical compounds that contain only the elements carbon and oxygen?
The law that explains relationships between different chemical compounds containing only carbon and oxygen is the law of multiple proportions. This law states that when elements combine to form more than one compound, the mass ratios of one element to the other will be a simple whole number ratio.
How did lavoisier distinguish between compounds and elements?
Lavoisier distinguished between compounds and elements by conducting experiments to show that compounds can be broken down into simpler substances, while elements cannot be further broken down by chemical means. He also proposed the Law of Conservation of Mass, which states that the total mass of substances present before a chemical reaction is equal to the total mass after the reaction, providing further evidence for the distinction between compounds and elements.
What do all compounds have in common?
All the compounds have at least two different types of atoms, they have mass and volume.
What Elements combine in fixed mass ratios to form compounds This must mean that elements?
In chemical compounds, elements combine in fixed ratios by mass to form stable, distinct substances. This observation is summarized in the law of definite proportions, which states that a compound is always composed of the same elements in the same proportions by mass. This principle demonstrates the predictable and reproducible nature of chemical reactions.

It involves analyzing the stoichiometric coefficients in a balanced chemical equation to determine the relative masses of reactants and products.

Which makes up most------single elements or compounds?
In terms of the total mass of the universe, it is single elements.
What law explains relationships between different chemical compounds that contain only the elements carbon and oxygen?

What do all compounds have in common?
All the compounds have at least two different types of atoms, they have mass and volume.
Have mass and takes up space is it an element or compound or both?
Both elements and compounds have mass and volume (take up space).
What Elements combine in fixed mass ratios to form compounds This must mean that elements?
In chemical compounds, elements combine in fixed ratios by mass to form stable, distinct substances. This observation is summarized in the law of definite proportions, which states that a compound is always composed of the same elements in the same proportions by mass. This principle demonstrates the predictable and reproducible nature of chemical reactions.
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.
Why did Mendeleev arrange elements in periods?
He arranged the elements in the increasing order of atomic mass and repeating properties so that it is easy to study the properties / reactivities of the elements.
The scientific statement that says that compounds always have exactly the same composition by mass is?
The law of definite proportions states that compounds always contain the same elements in the same proportion by mass. This means that the ratio of elements in a compound is consistent and does not change.
Does the compounds C2H2 and C6H6 have the same percent composition by mass?
It does not necessarily mean that. For example glucose (C6H12O6) and formaldehyde (CH2O) have the same percentages of elements by mass, but are two very difference compounds.
How elements arrange?
On the periodic table, the elements are arranged by Atomic Mass. Helium and Hydrgen are at the way top of the table due to how they have the smallest amount of mass. The elements with the biggest mass are at the bottom.
