Question

write equation for reaction of calcium and potassium with water​

Answer 1

Answer:

calcium with water: ... Potassium reacts violently with cold water to form potassium hydroxide and hydrogen gas:

2K(s)+ 2H2O(l) --------> 2KOH(aq) + H2(g) + heat.

Explanation:

In this reaction so much heat is produced get hydrogen gas formed catches fire and burns explosively.

Answer 2

Explanation:

QUESTION :-

What is the equation for the reaction of calcium and potassium in water?

ANSWER :-

Calcium and potassium do not react with each other, but each decomposes water to make the relevant hydroxide with the release of hydrogen.

The equation of reaction of calcium with water :-

Ca + 2H₂O → Ca(OH)₂ + H₂.

The equation of reaction of potassium with water :-

2K + 2H₂O → 2KOH + H₂.
