In single-replacement reactions, the true statement is that the element replacing the ion in the other reactant must be more active. This type of reaction can involve both metals and nonmetals and produces two products. Therefore, the reactivity of the elements is crucial in determining whether a reaction will occur. ;
The correct statement about single-replacement reactions is that the element replacing the ion in another reactant must be more active. This reaction type produces two products and can involve both metals and nonmetals. The reactivity of the elements is essential for determining if a displacement will occur.
