Intramolecular bonds (such as ionic or covalent bonds) can be broken down by a chemical change.
A mixture is a combination of two or more substances that do not undergo a chemical change and can be separated by physical means. Each component in a mixture retains its original properties.
Chemical, When something changes in color, it is a sign of a chemical change.
Water can be separated into hydrogen and oxygen through a chemical change called electrolysis, which uses an electric current to break apart the water molecules. Boiling water is a physical change that only changes the state of the water from liquid to gas, but it does not separate the water into its component elements.
Extraction is considered a physical change because it involves separating substances based on their physical properties, such as solubility or boiling point, without changing the chemical composition of the substances being separated.
Physical change occurs when sulfur and sodium chloride are separated. This is because their chemical compositions remain the same, but their physical states are altered when they are no longer combined.
This is a chemical change.
It is a chemical change.2NaCl --> 2Na + Cl2
The substance is a compound, which forms chemical bonds that cannot be physically separated, but only by a chemical change.
This is a chemical process.
a mixture
With ionic compounds anyway, they dissociate into their ions. The chemical change is an equilibrium until separated.
This is a chemical process.
Explain how a mixture of sand and salt can be separated.
A chemical change occurs because compound is two elements put together so when they are separated it forms a new substance.
A mixture is a combination of two or more substances that do not undergo a chemical change and can be separated by physical means. Each component in a mixture retains its original properties.
It is a chemical change (reaction) because the chemical composition of the products (O2 and H2) is different from the chemical composition of the water (H2O).
A Substance that can be separated into two or more substances is call a Composition, if not try Solution.----- ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- -----From Rafaelrz.Yes. A substance that can only be separated into two or more substances by a chemical change is a 'compound'. If a body can be separated into two or more different substances by only physical processes, then the body is a 'mixture'.
