Answer 2

Answer:

HI MATE

HERE IS YOUR ANSWER

METAL + WATER ----SALT +HYDROGEN

example -

• NA + H2O --- N2O + H2

Almost all metals react with water but with different intensities.

1. Sodium and potassium react violently with cold water to an extent that hydrogen gas so produced catches fire.

2. Calcium reacts less violently with water.Ca + 2H2O → CaOH2 + H2 ↑

3. Magnesium reacts with hot water to form magnesium oxide and hydrogen.Mg + H2O → MgO + H2 ↑

4. Metals like aluminium zinc and iron react only with steam.

5. Metals like gold silver and copper do not react with water.
