D

Explanation

A chemical reaction is always associated with a rearrangement of atoms. In a chemical reaction, one or more substances, called reactants, are transformed into one or more different substances, called products. This transformation involves the breaking and forming of chemical bonds between atoms.

The law of conservation of mass states that the total mass of the reactants in a chemical reaction is equal to the total mass of the products. This means that atoms are neither created nor destroyed in a chemical reaction; they are simply rearranged to form new substances.

Chemical reactions can be represented using chemical equations, where the chemical formulas of the reactants and products are written using chemical symbols and formulas. The coefficients in the equation indicate the relative quantities of each substance involved in the reaction.

There are different types of chemical reactions, including synthesis (combination), decomposition, combustion, displacement, and redox reactions. The specific characteristics of each type of reaction depend on the nature of the reactants and the conditions under which the reaction occurs.
