Thermodynamics is the branch of physics concerned with the conversion of different energy forms.
•DeltaG (rxn) = DeltaG (pdts) - DeltaDG (rcts) •DeltaG°(rxn) = -R T ln K •
A liquid with something dissolved in it
Heterogeneous means of different types. So a heterogeneous mixture is a mixture of dissimilar items. Homogeneous means of the same type so a homogeneous mixture would be a mixture of similar items.
A mixture where two or more substances are mixed together but are not chemically combined is called as an heterogeneous mixture.
In chemistry, heterogeneous mixture is a mixture of two or more different substances in the form of solution or colloids. For example, salad is an heterogeneous mixture
A heterogenous mixture is not uniform in composition and properties throughout.
Alloys are useful (if this is what the question is getting at) because mixing elements of the periodic table alters their colligative properties.
i.e. mixing two metals could change substance's melting point, allowing it to more easily resist high temperatures. Also, mixing metals can change the way they bind together, and create an altogether stronger material than you can find using any single metal alone.They can improve a metal's properties

Its polar end mixes with the water so it can be washed away. ~APEX
It exposes more of the solute surface to the water molecules.
