chemical formula
Chemical compounds are formed from chemical elements.
no both iron and silicon are elements. chemical compounds aretwo or more elements.
Formation of some compounds by chemical reactions
Elements become compounds after chemical reactions.
They can be! Compounds can certainly be decomposed into individual elements in a chemical reaction.
The formation of gas is:- a chemical process if the gas is the product of a chemical reaction- a physical process if the gas is the product of a change of phase as sublimation and vaporization
Chemical elements are combined to produce chemical compounds.
Salts are chemical compounds not elements.
When elements and compounds combine to form new compounds the reaction is described in a chemical equation.
Dalton proposed that elements combine in simple whole number ratios to form compounds, based on his atomic theory. He suggested that atoms of different elements combine in specific ratios to form compounds, where each compound has a unique composition. This explanation laid the foundation for understanding chemical reactions and the formation of compounds.
Chemical reactions occur when atoms of elements or compounds interact to form new compounds through the breaking and making of chemical bonds. This process can result in the formation of new substances with different properties than the original reactants.
Today are known approx. 65.106 chemical compounds.
