Solution

The homogenous mixture has all the components in the same phase.
Phenol and water are miscible. They both are present in liquid state.
Sugar is present in solid-state whereas benzene is present in a liquid state. Thus, they form a heterogeneous mixture.
Silver chloride is a white crystalline solid whereas water is in the liquid state thus they form a heterogeneous mixture.
Ethyl alcohol and water both are present in liquid state and are polar liquid. Thus, they form a homogenous mixture.
