When a chemical reaction occurs, bonds in the reactants break, while new bonds form in the product. The following example explains this. Hydrogen reacts with oxygen to form water, according to the following equation:
2H 2(g)+O2(g)→2H2O(g)
2H2(g)+O2(g)→2H2O(g)
In this reaction, the bond between the two hydrogen atoms in the
