These compounds are called isomers.
An element can exist in different forms called allotropes, which have the same chemical composition but different structures. For example, carbon can exist as graphite, diamond, or fullerene. These different forms of elements can have distinct physical and chemical properties.
Isomers
differentiation
Two different minerals can have the same chemical composition if they have different crystal structures. The way atoms are arranged and bonded in a mineral's crystal lattice can determine its unique physical properties, even if the chemical elements present are the same. This phenomenon is known as polymorphism.
The type of weathering that does not alter the chemical composition of the rock is called physical weathering. The acid weathering usually alter the chemical composition of a rock.
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
Chemical Substance
Isomers are pairs of molecules that share the same chemical formula but have different structural arrangements. For example, glucose and fructose both have the chemical formula C6H12O6, but they have different structural arrangements.
The eubacteria and that chemical composition is called peptidoglycan.
Light is made up of particles with wave properties called "photons". It has no chemical composition.
It's called chemical weathering/chemical change. Similar to the physical change of matter, except the chemical composition changes causing it to become something completely different. For example: iron turns to rust, silver tarnishes and copper turns green.
A material with definite properties and definite chemical composition is called a pure substance.
