A small sample from a vial of phenol melts at 39-40 °C. A larger sample from the same vial melts at 39-43 °C.
a) Does the wider range mean the larger sample is less
pure?
b) Does the wider range mean the larger sample is more pure?
c) Explain why the larger sample has a higher, wider range.
*** I learned that a wider range means that a sample is impure. However, I'm wondering why the size of the sample could cause this wider range, instead of impurities.

Running the Reaction Add 0.100 g benzil and 0.30 mL 95% ethanol to a 3-mL conical vial. Place a spin vane in the vial and attach an air condenser. Heat the mixture with an aluminum block (90-100°C) while stirring until the benzil has dissolved (see inset in Tech- nique 6, Figure 6.1A).

My Ask You C-reactive protein (CRP) is a substance that can be measured in the blood. Values increase substantially within & hours of an infection and reach a peak within 24 to 48 hours after. In adults, chronically high values have been linked to an increased risk of cardiovascular disease. In a study of apparently healthy children aged 6 to 60 months in Papua New Guinea, CRP was measured in 90 children. The units are milligrams per liter (mg/l). Here...

Introduction: The technique used to separate an organic compound from a mixture of compounds is called Extraction. Extraction process selectively dissolves one or more of the mixture compounds into a suitable solvent. The solution of these dissolved compounds is referred to as the Extract. Here the organic solvent dichloromethane is used to extract caffeine from an aqueous extract of tea leaves because caffeine is more soluble in dichloromethane (140 mg/ml) than it is in water (22 mg/ml). However, there are...
