What is composed of atoms in a fixed proportions?
Molecule.
What is composed of atoms in fixed proportions?
Chemical compounds are composed of atoms in fixed proportions. The ratio of elements in a compound remains constant regardless of the amount of the compound present.
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.
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.
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.
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.
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.
What do all compounds have in common?
All the compounds have at least two different types of atoms, they have mass and volume.
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 is any material that is made of two or more substances?
a compound no,it is a "mixture". a specific "compound" must be composed of different kinds of chemically combined (electronically bonded)atoms in fixed proportions. e.g. Methane (CH4) is a different compound than Ethane (C2H6)
