How do homogeneous mixture differ from heterogenous mixture? Where does the compound table salt (NaCl) fit into this description?

Yes he is right good job

Homogeneous - the mixture is even throughout the solution cannot tell one part from another

heterogenous - the mixture is not mixed even and you can tell one compound from another.

NaCl is a homogeneous solution since you cannot visibly separate the NaCl from the water it is dissolved in.
