Question

write the balanced chemical equation for the synthesis of potassium chloride. a) k + cl₂ → kcl b) 2k + cl₂ → 2kcl c) k + cl → kcl d) k + cl₂ → kcl₂ what is the general form of a single displacement reaction for a metal reacting with an ionic compound? a) a + bx → ax + b b) a + bx → abx c) ax + by → ay + bx d) ax + by → ab + xy

Explanation:

Step1: Analyze potassium chloride synthesis

Potassium (K) reacts with chlorine gas ($Cl_2$). Chlorine is di - atomic in its elemental form. To balance the equation, 2 potassium atoms react with 1 molecule of chlorine gas to form 2 molecules of potassium chloride (KCl). The balanced equation is $2K + Cl_2
ightarrow2KCl$.

Step2: Analyze single - displacement reaction form

In a single - displacement reaction where a metal (A) reacts with an ionic compound (BX), the metal displaces the cation in the ionic compound. The general form is $A + BX
ightarrow AX + B$.

Answer:

1. B. $2K + Cl_2

ightarrow2KCl$

1. A. $A + BX

ightarrow AX + B$
