Copper and oxygen atoms form to create copper oxide. This is a synthesis reaction, and it can be created when copper is burned in a fire.
They are rearranged
When copper reacts with alcohol, it forms copper acetate and hydrogen gas. This reaction is a chemical process where the copper atoms combine with the alcohol molecules to create a new compound.
something happens
During a chemical reaction, atoms are rearranged and bonded together in new ways, forming different substances. The total number of atoms remains the same before and after the reaction, as atoms are neither created nor destroyed in a chemical reaction.
They are rearranged
The atoms involved in a chemical reaction have their bonds broken, new bonds formed, or existing bonds rearranged depending on the reaction type.
Individual atoms in a chemical reaction are rearranged to form new chemical compounds. Atoms are not created or destroyed in a chemical reaction, only the way they are arranged changes. The total mass and number of atoms of each element involved in the reaction remain constant, following the law of conservation of mass.
When copper reacts with acid, such as hydrochloric acid, it undergoes a chemical reaction that produces copper chloride and hydrogen gas. This reaction is a type of single displacement reaction, where the copper atoms replace the hydrogen atoms in the acid. The copper chloride formed is soluble in water, while the hydrogen gas is released as a byproduct.

During a chemical reaction, bonds between atoms are broken and new bonds are formed. Atoms rearrange to form new molecules or compounds, resulting in a change in the chemical properties of the substances involved in the reaction. Energy may be absorbed or released during these bond formations and breakages.
The materials produced in a chemical reaction are called products. These products are formed as a result of the rearrangement of atoms in the reactants during the reaction.
