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.

Why greek prefixes is used in covalent compounds?
Greek prefixes are used in covalent compounds to indicate the number of atoms of each element present in the molecule. This naming system helps to distinguish between different compounds with the same elements but in different proportions. The prefixes provide a clear and systematic way to communicate the composition of the molecule.
What is the easiest way to distinguish an ionic compound from a covalent bond?
One way to distinguish between an ionic compound and a covalent bond is to observe the difference in electronegativity between the atoms involved. Ionic compounds typically form between elements with a large difference in electronegativity, leading to the transfer of electrons, while covalent bonds form between elements with similar electronegativity, resulting in the sharing of electrons. Additionally, ionic compounds tend to have high melting and boiling points due to the strong electrostatic forces between ions, whereas covalent molecules have lower melting and boiling points.
Is the composition of an ionic compound formed by two or more nonmetallic elements?
No, ionic compounds are formed by the transfer of electrons between a metal and a nonmetal. Nonmetallic elements typically form covalent compounds where they share electrons rather than transfer them.
Which statement describes a chemical property that can be used to distinguish between compound A compound B?
One chemical property that can be used to distinguish between two compounds is their reactivity with a specific reagent to form a unique product. For example, if compound A reacts with a specific metal to form a colored precipitate while compound B does not, this difference in reactivity can be used to distinguish between the two compounds.
Do elements combine to make compounds?
Yes, elements combine in specific ratios to form compounds. A compound is a substance made up of two or more different elements chemically bonded together. The chemical bonds between elements in compounds are formed through interactions at the atomic level.
Difference between elements and compounds reacting?
the ease with which the elements can be separated.

What is the relationship between atoms and compounds?
Compounds are composed of two or more atoms of different elements.

Compounds can be separated into their constituent elements only by what reaction?
Compounds can be separated into their constituent elements only by chemical reactions. These reactions involve breaking the bonds between the atoms in the compound to release the individual elements.

One chemical property that can be used to distinguish between two compounds is their reactivity with a specific reagent to form a unique product. For example, if compound A reacts with a specific metal to form a colored precipitate while compound B does not, this difference in reactivity can be used to distinguish between the two compounds.
What is the study of reactions between elements and compounds?
phisics
Is the sharring of electrons by elements to form compounds?
Sharing or electrons between atoms results in the formation of covalent compounds.
What are the similarities between mixtures and compounds?
the similarities between compounds and mixtures are that they are both made up of two or more elements and that they could both be separated and then mixed with different elements to make a new mixture and compound.
Do elements combine to make compounds?
Yes, elements combine in specific ratios to form compounds. A compound is a substance made up of two or more different elements chemically bonded together. The chemical bonds between elements in compounds are formed through interactions at the atomic level.
What 3 elements do all carbon compounds have in common?
All carbon compounds have carbon atoms, covalent bonds between carbon atoms and other elements, and exhibit organic chemistry properties.
