Here, the definition is given and asked for a word that is defined.
The rearrangement of atoms by breaking and reforming chemical bonds is called a chemical reaction.
Hence, "chemical" is the missing word.
A chemical reaction is the rearrangement of atoms by breaking and reforming chemical bonds.
Answer:
Chemical
Explanation:
A chemical reaction is the rearrangement of atoms by breaking and reforming chemical bonds. This can further be explained by the following chemical reaction:
Acid react with a base to produce salt and water. This can be seen when hydrochloric acid (HCl) react with sodium hydroxide according to the balanced equation:
HCl + NaOH —> NaCl + H2O
The above is simply a chemical reaction as the bond in HCl breaks up and likewise the bond in NaOH. The atoms are rearranged, forming a new bond by producing salt (NaCl) and water (H2O)
