Happen when metal what happen when metal react with water with water whatcha
Answers
Answer:
ExplanAll the alkali metals react vigorously with cold water. In each reaction, hydrogen gas is given off and the metal hydroxide is produced. The speed and violence of the reaction increases as you go down the group. This shows that the reactivity of the alkali metals increases as you go down Group 1.
Magnesium does not react with cold water. It reacts with hot water to form magnesium hydroxide and hydrogen.
Metals like Aluminium, Iron and zinc does not react either with cold or hot water. But they react with steam to form metal oxide and hydrogen. 3Fe + 4H2O gives rise to Fe3O4 + 4H2.ation:
Answer: When metals react with water, metal oxides and hydrogen is formed. Further, if the metal oxides are soluble in water then metal hydroxide is formed.
