Anything larger than a single atom.
Compounds -- that is, substances chemically made from more than one species of atom -- can be chemically separated into their elemental parts. H2O can be seperated by electricity into H2 and O2. 2(H2O) + charge --> 2H2+O2
The process by which matter is changed into new substances is called a chemical reaction. During a chemical reaction, atoms are rearranged to form different molecules with new properties compared to the original substances.
When one or more new substances is created, the change is called a chemical change. A chemical change has occurred if there is a new substance created, there was energy released or absorbed, or the substances no longer exhibit the same chemical properties.
You think probable to isomers.
No, changes in state of matter (such as melting, freezing, boiling) are physical changes, not chemical changes. Chemical changes involve the formation of new substances with different chemical properties.
No, matter cannot change states after a chemical change. A chemical change involves the rearrangement of atoms to form new substances, which may have different properties than the original substances. However, the state of matter (solid, liquid, gas) itself remains the same throughout the chemical change.
Matter can be separated through physical or chemical means. Physical methods include filtration, distillation, and chromatography, which separate substances based on their physical properties. Chemical methods involve chemical reactions to convert substances into different forms, allowing for isolation of specific components.
chemical properties can be observed only when the substances in a sample of matter are changing into different substances

Chemical Properties can be observed only when substances in a sample of matter are changing into different substances.
Yes, when matter undergoes a chemical change, the composition of the matter changes at the molecular level. New substances are formed with different chemical properties than the original substances.
Matter is classified as mixtures and substances. Mixtures are composed of two or more different substances that are physically combined, while substances are pure forms of matter that cannot be separated by physical means. Substances are further divided into elements and compounds.
A mixture is formed when different types of matter are combined physically, not chemically. These substances can be separated by physical means, such as filtering or evaporation. Each component in a mixture retains its own properties and does not create a new substance.
The process by which matter is changed into new substances is called a chemical reaction. During a chemical reaction, atoms are rearranged to form different molecules with new properties compared to the original substances.
Substances formed in chemical changes have different physical and chemical properties compared to the original substances. This can include changes in color, odor, state of matter, melting/boiling points, and reactivity. The chemical composition of the new substances is also different from the original substances.
When one or more new substances is created, the change is called a chemical change. A chemical change has occurred if there is a new substance created, there was energy released or absorbed, or the substances no longer exhibit the same chemical properties.
A mixture is a sample of matter that can be separated into different substances by physical means. This can include techniques such as filtration, distillation, or chromatography to isolate the individual components.
Elements cannot be separated into simpler substances or converted into another substance by chemical processes. Elements are the building blocks of matter and are represented on the periodic table by unique symbols.
