What is a substance formed by the combination of two or more elements in definite proportions?
A chemical compound. The combination of two or more elements in definite proportions forms a compound. For instance, hydrogen and oxygen combine in a two to one ratio in order to form water. Similarly, one sodium atom reacts with one chlorine atom to form the ionic compound sodium chloride.
Is a compound formed by two positive elements?
No, two positives are repelling, not attracting. No. Compounds are formed by two or more different elements. An ionic compound is formed by the attraction between two oppositely charged ions. Molecular compounds are formed by the sharing of electrons between atoms, which is called a covalent bond.

Why are DNA water and sodium chloride all classified as chemical compounds?
DNA, water, and sodium chloride are classified as chemical compounds because they are all composed of two or more different elements chemically bonded together. In DNA, nitrogenous bases, sugars, and phosphates are combined to form the molecule. Water is composed of two hydrogen atoms and one oxygen atom bonded together. Sodium chloride is a compound formed by the ionic bond between sodium and chloride ions.
Most of the chemical elements can be divided into 2 groups what are these 2 groups?
Chemical elements can be divided into metals and non-metals. Metals typically have properties like luster, conductivity, and malleability, while non-metals are generally less shiny, poor conductors, and more brittle.
What is the substance formed by the chemical combination of two or more elements in definite proportion?
A compound is the substance formed by the chemical combination of two or more elements in definite proportions. It has a unique chemical structure and properties different from its constituent elements.
What is formed when two or more elements are chemically combined?
Compound is formed by the chemical combination of two or more substances.
What are formed when two or more elements chemically combine?
Compound is formed by the chemical combination of two or more substances.
What is formed when two or more elements combined chemically?
Compound is formed by the chemical combination of two or more substances.

What is a substance formed by the chemical combination of two or more elements in a fixed or definite ratio?
This is is a stoichiometric chemical compound.
What is a compoound mean in science?
In science, a compound is a substance formed by the chemical combination of two or more elements in definite proportions. Compounds have unique properties different from those of their constituent elements. Examples include water (H2O) and carbon dioxide (CO2).
What is a pure substance which is formed by a chemical reaction between two or more different substances called?
A compound is the pure substance formed from the chemical combination of two or more different elements.
What is a substance formed from two or more elements form when chemically combined in a set ratio?
A compound is a chemical combination of two or more elements in a fixed ratio.
Substance formed by the chemical combination of two or more elements in definite proportion?
A compound is formed by the chemical combination of two or more elements in definite proportions. The atoms in compounds are held together by chemical bonds, and compounds have unique properties that are different from the elements that make them up. Examples of compounds include water (H2O) and sodium chloride (NaCl).
Why is carbon dioxide a compound?
Yes, it is a compound because it is formed from a chemical combination of two or more elements and can be broken down.
