What happens in a combustion reaction? In a double replacement reaction, the components of two compounds are exchanged (or displaced) to form two new compounds. Occasionally, the mixture may bubble as a gas is produced. In this equation, Fe and H as well as O and Cl trade places. the elements in two compounds switch places - Apex, in a double replacement reaction the more reactive metal The OH-ions combine with the H + ions to produce water, while the Na + ions combine with the Cl-ions to produce sodium chloride. A double-replacement reaction is a reaction in which the positive and negative ions of two ionic compounds exchange places to form two new compounds. An example of a neutralization reaction is when sodium hydroxide (NaOH) and hydrochloric acid (HCl) are dissolved in water and react. Mg + CuCl → d) two reactants combine to form one compound. For instance, when Iron is added to a copper sulphate solution, it displaces the copper metal.
