Answer:
Reactions of Metals with Water
Metals with moderate to low reactivity react very slowly with water. However, they react moderately with steam when heated and give hydrogen gas and metal oxides. Metals low in the metal reactivity series do not react with water even at high temperature.
Explanation:
Order of reactivity Metal Reactions with water or steam
↑ sodium (Na) Vigorous reaction with cold water
↓ calcium (Ca) Less vigorous reaction with cold water
least reactive magnesium (Mg) Slow reaction with cold water, vigorous . with hot water
