Describe at least two procedures for detecting halogens and their positive results.When is sieving and fractional distillation a good method for separating mixtures? Cite an example.when drawing melting point composition diagram for a mixture of something such as cinnamic acid and urea comparing melting point vs composition for organic chemistry, if i have three different compositions (1:4, 4:1,1:1) should i have 3 different graphs or would this all be on the same graph? and how do i convert grams to moles for example for composition 1:4 my data was 0.8003 g : 3.1917 g?
