Question

Write a balanced chemical equation for the reaction of solid potassium with liquid water. express your answer as a chemical equation. identify all of the phases in your answer.

Answer 1

Answer : The balanced chemical reaction will be,

`2K(s)+2H_2O(l)\rightarrow 2KOH(aq)+H_2(g)`

Explanation :

Balanced chemical reaction : It is defined as the number of atoms of individual elements present on reactant side must be equal to the product side.

As per question, when solid potassium react with liquid water then it gives potassium hydroxide solution and hydrogen gas as a product.

Thus, the balanced chemical reaction will be,

`2K(s)+2H_2O(l)\rightarrow 2KOH(aq)+H_2(g)`

In this reaction, potassium is in solid state, water is in liquid state, potassium hydroxide is in aqueous state and hydrogen is in gaseous state.

Answer 2

In writing chemical reactions, it is important that you know the chemical formula of each substance and in balancing them, it should be that the number of each element in both side are equal.

2K(s) + 2H2O(l) = 2KOH(aq) + H2(g)
