Guys pls answer this question its urgent!!!!
Explain the reactivity of metals with water?
Answers
Explanation:
Metals react with water and produce a metal oxide and hydrogen gas. Metal oxides that are soluble in water dissolve in it to further form metal hydroxide. But all metals do not react with water. Metals like potassium and sodium react violently with cold water.
Answer:
Metals react with water to form Metal hydroxide and hydrogen.
Metal+H2O----> Metal hydroxide + H2
Heat is also being evolved during the reaction.
For eg:
take the case of sodium. When added to normal water or even cold water, it figets on the surface of the liquid. Why does this happen?
Beacause of hydrogen gas. It makes the sodium move to different directions.
Next the heat: The heat evolved is very high.
And also sodium reacts very fast and dissipates soon from its contact with water. Sodium is highly reactive.
Na + H2O --------> Naoh + H2 + heat
The different reaction with metal and water depends on the reactivity of the metal.
