An activity series is used to predict whether metals will displace hydrogen gas from water and acid solutions. It is also used to predict whether metals will displace other metals.
In single-displacement, if the activity of the free element is greater than the element in the compound, the reaction will happen.
Using activity series you can predict chemical reactions as double displacement reactions, metals reactions with acids, metals reactions with water, extraction of metals.
_Answer">Metals higher in the series will replace metal ions in solution that are lower in the series. AnswerIn general, the more "reactive" (electro-positive) the metallic element, the more stable will be the compounds it forms with other elements. AnswerThe activity series can be used to predict whether or not a reaction will occur -- in other words, a yes-or-no answer. It cannot be used to predict what the products of the reaction are, which is entirely dependent on the specific reactants. See the Related Questions about cupric sulphate and an iron nail for a good description of how to use the activity series to predict if a reaction will happen or not.

The decomposition reaction is:MgCO3 = MgO + CO2
An element's physical and chemical properties. You can also predict what elements will bond with each other.
A periodic table can predict elements that are not yet confirmed or identified.

An activity series of metals can predict whether a replacement (displacement) reaction will occur. You use the activity series to compare the reactivity of different metals in order to predict whether a replacement reaction will occur. A metal that is above another metal in the series will replace that metal in a compound.
