Question

write balanced equation for the reaction of sodium , potassium and calcium in cold water​

Answer 1

Answer:

2Na+2H2O-2NaOH+H2

2K+2H2O-2KOH+H2

2Ca+2H2O-Ca(OH)2+H2

Explanation:

Sodium and potassium reacts violently with cold water whereas calcium reacts readily with cold water and large amount of heat is released.

Answer 2

Answer:

2Na+H2O=2NaOH+H2

2K+2H2O=2KOH+H2

2Ca+2H2O =Ca(OH)2+H2
