Ответ:
a heterogeneous mixture,-two substances present; two phases present
a homogeneous mixture- two substances present; one phase present
a pure substance- one substance present- one phase present
no correct response-one substance present; two phases present
Explanation:
When two substances are mixed, the mixture may be homogenous or heterogeneous. If a mixture is homogenous, then the two substances form a single phase, e.g ethanol and water.
On the other hand, a heterogeneous mixture is divided into two distinct phases, e.g kerosene and water mixture.
A single substance can only give one phase, no substance can simultaneously give two phases of the same substance in the same physical state.
Similarly, a pure substance always consists of a single phase.
