A double displacement reaction is a type of chemical reaction in which two compounds react in order to create two new chemicals. The two cations and anions switch places with each other which forms two new compounds. As an example AB+CC can switch to AD+CB. Both sides of these equations must balance out in order to be neutral. So any pairs of compounds (such as A+B) must have a total balanced charge. In this example A could have a charge of positive 2 (+2) and B could have a charge of negative

Changes: Types of Chemical Reaction INTRODUCTION Chemical changes are results of chemical reactions. All chemical reactions involve a change in substance and a change in energy. They are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products. There are different types of chemical reaction classified into 4 general types‚ namely‚ Synthesis‚ Decomposition‚ Single Replacement and Double Replacement
