13. Solving a chemistry problem

6. Based on the data (composition, temperature) of the precipitation of the first crystal, construct a state diagram for a conditional system of substances.
2) Determine the qualitative and quantitative composition of the eutectic mixture.
3) Draw schematically all types of cooling curves possible in the given system. Indicate which compositions in the diagram these curves correspond to.
4) Calculate the number of degrees of freedom for the system given by the figurative point coordinate.
5) "Arrows" show the processes of cooling the system until complete solidification. All processes occurring in this case are described in detail.
