Vedclass · Answer

(B) The reactivity of metals with water is determined by their position in the reactivity series. Potassium $(K)$ is a highly reactive alkali metal that reacts vigorously with cold water. Magnesium $(Mg)$ reacts with hot water. Zinc $(Zn)$ reacts with steam. Gold $(Au)$ is a noble metal and does not react with water. Therefore,the decreasing order of reactivity is $K > Mg > Zn > Au$.

The order of reactivity of $K$,$Mg$,$Zn$,and $Au$ with water is
