Suppose you have an unknown X that melts at 85-86oC and you do a mixture melting point with a known compound A that melts at 85-86oC. What results would be observed if:
a. If X is identical with A, the melting point of the mixture would be (greater than, less than, equal to) 85-86oC and the melting point range would be (larger than, less than, equal to) 1oC.
b. If X is not identical with A, the melting point of the mixture would be (greater than, less than, equal to) 85-86oC and the melting point range would be (larger than, less than, equal to) 1oC.
