Who is results demonstrated that elements combine in specific proportions because they are made of individual atoms?
The law of definite proportions was proposed by Joseph Proust, a French chemist, in the late 18th century. He demonstrated through experiments that elements combine in specific proportions by mass because they are composed of individual atoms with fixed ratios.
What are composed of atoms?
All matter is composed of atoms, which are the basic building blocks of all elements. Atoms consist of a nucleus made up of protons and neutrons, surrounded by a cloud of electrons. The arrangement and interactions of these atoms determine the properties and behavior of different substances.
How is a quartz crystal not classified as either a solid or a liquid?
A quartz crystal is classified as a solid because its atoms are arranged in a fixed, orderly pattern. This distinguishes it from liquids, which have atoms that move more freely and do not have a fixed structure.
Atom are composed of neutrons and electrons?
Atoms are composed of neutrons, protons, and electrons. Neutrons and protons make up the nucleus of the atom, while electrons orbit around the nucleus in specific energy levels or shells. The number of protons in the nucleus determines the element of the atom.
Are atoms real?
there is no direct evidence but its a theory but can be proven

A substance composed of two or more kinds of atoms always in the same ratio?
This substance is called a compound. Compounds are formed when atoms of different elements chemically bond together in fixed proportions. The ratio of these atoms in a compound is constant and is represented by a chemical formula.
How are compounds diffident from mixtures?
Compounds are composed of atoms of different elements chemically bonded in definite proportions. The components of mixtures are not chemically combined and they do not have definite proportions.
Dalton's fourth postulate states that atoms combine?
Dalton's fourth postulate states that atoms combine in simple whole-number ratios to form compounds. This postulate laid the foundation for the law of definite proportions and the law of multiple proportions in chemical reactions and helped in the development of modern atomic theory.
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.
A compound is composed of one or more combined in fixed ratios?
A compound is a substance made up of two or more different elements chemically bonded together in fixed proportions. These proportions are determined by the chemical formula of the compound, which specifies the types and numbers of atoms present in the compound.
Is a compound a chemical combination of atoms whose proportions do not vary?
Yes, a compound is a substance made up of two or more different types of atoms chemically bonded together in fixed proportions. The ratio of atoms in a compound remains constant regardless of the amount of the compound present.
What do all compounds have in common?
All the compounds have at least two different types of atoms, they have mass and volume.
Are the proportions of a mixture fixed or not fixed?
The proportions of a mixture can be fixed or not fixed, depending on the specific components and how they are combined. In a homogeneous mixture, such as a solution, the proportions of the components are fixed. In a heterogeneous mixture, such as a mixture of solids, the proportions can vary throughout the sample.
