Question

write balanced equations for the reaction of Sodium Potassium and calcium in cold water

Answer 1

Hey There!

________________________________

Sodium = Na (Atomic Number : 11)

Potassium = K (Atomic Number : 19)

Calcium = Ca (Atomic Number : 20)

Following Reaction Takes place when we add all these in cold water.....

Na + K + Ca + 4H2O ===> NaOH + KOH + Ca(OH)2 + 2H2 (Gas)

Note : in H2O and H2 and Ca(OH)2 here, 2 is subscript
