Answer
acid
Explanation
## The reactivity series or activity series is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their reactivity from highest to lowest. It is used to summarize information about the reactions of metals with acids in terms of the reactivity of the metal.## The question asks for the completion of the sentence where the reactions with water and something else are mentioned to arrange metals in the reactivity series. The other reagent apart from water, which usually metals react with to show their reactivity, is 'acid'. ## Acids tend to donate hydrogen ions, causing metallic atoms to change into cations specifically by loss of electrons. Different metals display varied tendencies for the loss of electrons leading to a variety of reactions with acids showing variable reactivity. Consequently, the missing word in the largely interpreted combination would be 'acid'.
