Question

using the letters a,b an c create a model of a single replacement reaction
abc --> ac + b
a + bc --> b + ac
a + bc --> ab + c

Explanation:

Step1: Understand single - replacement reaction

A single - replacement reaction has the general form \(A + BC
ightarrow AC + B\) (where \(A\) replaces \(B\) in \(BC\)) or \(A+BC
ightarrow AB + C\) (where \(A\) replaces \(C\) in \(BC\)).

Step2: Analyze each option

• For \(ABC

ightarrow AC + B\), this is not in the form of a single - replacement reaction (\(A + BC\) as reactants).

• For \(A + BC

ightarrow B+AC\), this is in the form of a single - replacement reaction where \(A\) replaces \(B\) in \(BC\).

• For \(A + BC

ightarrow AB + C\), this is in the form of a single - replacement reaction where \(A\) replaces \(C\) in \(BC\).

Answer:

The correct forms of single - replacement reactions are \(A + BC
ightarrow B + AC\) and \(A + BC
ightarrow AB + C\).
