How do alkaline earth metals react with water?

Alkaline earth metals
Magnesium shows insignificant reaction with water, but burns vigorously with steam or water vapor to produce white magnesium oxide and hydrogen gas: Mg(s) + 2 H2O(l) ? Mg(OH)2(s) + H. A metal reacting with cold water will produce metal hydroxide.

Furthermore, how do alkali metals react with water?

Alkali metals react with water to produce heat, hydrogen gas, and the corresponding metal hydroxide. The heat produced by this reaction may ignite the hydrogen or the metal itself, resulting in a fire or an explosion. The heavier alkali metals will react more violently with water.

Also, how do alkaline earth metals react with iodine? When iodine was reacted with aqueous alkaline earth metal oxides (MgO, CaO, SrO and BaO) both metal iodate and iodide were formed. However these reactions were never complete. The percentage of products obtained was increased with excess I2 and water, and higher molecular weight oxide.

Subsequently, question is, which statement best describes how alkali earth metals react with water?

Answer: The right answer is: *Most alkali earth metals react with hot water.

What happens when the elements in group 2 react with water?

These all react with cold water with increasing vigour to give the metal hydroxide and hydrogen. You get less precipitate as you go down the Group because more of the hydroxide dissolves in the water. Summary of the trend in reactivity. The Group 2 metals become more reactive towards water as you go down the Group.
