2. It defines that when Metal react with water it form metal oxide and liberate hydrogen gas.
Ex. Ca + H2O ------> CaO + H2
3. It defines that when metal react with acid it form Salt and liberate Hydrogen gas
Ex. Fe + H2SO4 ------> FeSO4 + H2
If this answer is correct then plz mark as brainliest.
Metals such as potassium, sodium and lithium react with oxygen very quickly. Calcium and magnesium are slightly less reactive and react with oxygen less quickly. Metals like copper and mercury react with oxygen very slowly and need to be heated continuously in order to see this happening.
