Explanations:
Combination reaction is the combination of two or more elements to form a compound. From the listed equations, the the reaction that undergoes combination reaction will be:
For decomposition reaction, a compound is separated into its constituent elements. An example of a decomposition reaction will be:
For a single replacement reaction, two compounds are combined to produce an element and a compound. An example of a single replacement reaction will be:
A double replacement reaction involves the reaction between two soluble compounds to produce one soluble and one insoluble products. A double decomposition reaction will be:
