Organic chemistry help?

Question

1.two substance A and B have the same melting point. how can u determine if they are the same?

Answer 1

idk

Answer 2

you need to find their molecular mass...use the formula m/mr = m/mr

Answer 3

Test to see if A and B have the same freezing point at, heat conduction may be different from heat convection

Answer 4

basis of chemical are the same. o

Answer 5

there are several scans that would tell the chemical composition.

for example, HNMR and InfraRed scans will give you a better idea of what chemical structures and functional groups are involved.

Answer 6

Mix A and B and measure the melting point of the mixture. If they are the same, the melting point will not change. If they are different, the melting point will be lower and occur over a wider range.
