During a
(b)
Interpretation:
The balanced equation corresponding to the single-replacement reaction that occurs when a piece of radioactive radium is added to water is to be stated.
Concept introduction:
During a chemical reaction, the composition of the substance undergoes a change. In a single-replacement reaction, a more reactive element displaces another element from a compound or its solution. The substance that is displaced is less reactive and has lesser tendency to undergo reaction than the other element.
