For covalent compounds, the subscripts indicate the number of atoms of each element in a molecule. When naming a binary covalent compound, the subscripts become part of the name.
CO2 = carbon dioxide
CO = carbon monoxide
H2O = dihydrogen monoxide (common name water)
H2O2 = dihydrogen dioxide (common name hydrogen peroxide
SO3 = sulfur trioxide
S6O2 = hexasulfur dioxide
No, compounds contain two or more elements. These elements are bond by ionic or covalent bonds. Compounds have a single chemical composition.
Chemical equations represent chemical composition of reactants and products and also how does the reaction occur.
Chemical compounds are formed from chemical elements.
This is the compound, which consits of at least two elements.
An electric fan is not a chemical category at all, but an article of manufacture that can contain many chemical compounds and/or elements.
Only after experiments and determination of the chemical composition.
when 2 or more compounds react chemically to form a new compound then it is called chemical reaction chemical reaction whereas the quantity and no. chemical elements presents in chemical compound is called the chemical composition
This is a chemical reaction; the composition of reactants is changed.
It is a mixture.Dirt is a mixture. Dirt is made of different compounds and elements. They does not have a single chemical composition.
- All pure chemical elements are not chemical compounds.- Mechanical mixtures are not chemical compounds.- Also, electromagnetic and nuclear radiation, heat radiation, nuclear partices etc. are not chemical compouds. etc
Elements become compounds after chemical reactions.
All the properties are different for chemical elements and chemical compounds.
