Concrete is a mixture of different substances (compounds) not a sinle compound.
Any chemical that contains multiple base elements is termed a chemical compound. Chemical compounds are substances that contain two or more base elements. For example; carbon (C) and oxygen (O) are base elements, but carbon dioxide (CO2) is a compound consisting of one carbon and two oxygen molecules.
why helium does not react with other elements to form compounds
it started when we identified organic compounds
No - you use of the term "single element and compound" is meaningless - ALL compounds are made up of more than one element. You need to go back to you teacher and ask him/her to explain the basics of chemistry to you as you clearly do not understand them.
compound) is a pure chemical substance consisting of two or more different chemical elements[1
Concrete is a mixture of different substances (compounds) not a sinle compound.
Ionic compounds do not have prefixes but covalent compounds have prefixes. “Aluminum chloride” is a ionic compound and "boron tri-chloride” is a covalent compound.
selective solubility is a separation technique toremove a compound of a mixture. one of the compounds is highly soluble in the medium, whereas the other compound(s) are insoluble. in such a way the compound requested can be removed and purified
No because the elements that make up the compounds have different properties than the compound's properties.
An element is composed of only one kind of atom. A compound is composed of two or more elements (kinds of atoms) chemically combined.
Wax is a class of compounds, not a single compound. Paraffin wax is a mixture of alkanes with carbon number around 20-40: C20H42 to C40H82.
- The atom is representative for a chemical element (more exactly for an isotope); elements are formed from atoms. - A chemical compound contain two or more chemical elements. - A mixture contain two or more compounds.
the properties of an ionic compound can be explained by ht e strong attractions among ions within a crystal lattice.

can anyone please explain me the difference between the aliphatic hydrocarbon resin and aromatic hydrocarbon r Save resin.. its urgent.. regards, kanchan
A molecule of hydrogen has a formula of H2. It consists of only one kind of element. Compounds consist of two or more kinds of elements. Carbon dioxide, CO2, is a compound because it contains both the elements carbon and oxygen.
