change into new substances
The process that changes some chemical substances into other chemical substances is known as a chemical reaction. During this process, bonds between atoms are broken and formed, resulting in the transformation of reactants into products with different properties. Chemical reactions are fundamental to various natural and industrial processes, including combustion, fermentation, and synthesis.
No, chemical changes and physical changes are distinct processes that occur separately in a system. Chemical changes involve the formation of new substances with different chemical properties, while physical changes involve alterations in the state or appearance of a substance without changing its chemical composition. These processes do not typically occur simultaneously.
Chemical weathering changes the composition of materials through processes like oxidation, hydrolysis, and dissolution. These processes break down minerals into new substances, altering the chemical composition of the rock.
A reaction between two substances or the decomposition of a substance are chemical changes.

chemical changes
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.
The processes are called chemical reactions.
The chemical properties of an object show what a chemical change did to that substance.
A change in which one or more new substances are formed is called a chemical change or chemical reaction. During this process, the original substances undergo a transformation that alters their chemical composition, resulting in the creation of new substances with distinct properties. Examples include combustion, rusting, and digestion. Unlike physical changes, which do not create new substances, chemical changes often involve energy transfer and irreversible processes.
No, the growth of a plant is a physical change, not a chemical change. Chemical changes involve the formation of new substances with different chemical properties. In plant growth, no new substances are being formed, and the plant is simply increasing in size through processes like cell division and expansion.
After chemical reactions new substances are obtained.
