Answer to Question #125462 in Chemistry for jaismine kaur

Question

calculate the number of moles of Potassium Chloride which will be produced when 16 moles of Hydrochloric acid reacts with Potassium.

Answer 1

The equation of the reaction between potassium and hydrochloric acid is:

2K + 2HCl $\rightarrow$ 2KCl + H₂.

As one can see, when 2 mol of hydrochloric acid reacts, 2 mol of potassium chloride is produced. Therefore, the number of the moles of hydrochloric acid that reacts is equal to the number of the moles of potassium chloride formed:

$n(HCl) = n(KCl)$ .

Therefore, the number of the moles of potassium chloride formed is:

$n(KCl) = n(HCl) = 16$ mol.
