Brewed coffee is often too hot to drink right away. You can cool it with an ice cube, but this dilutes it. Or you can buy a device that will cool your coffee without dilution - a 220 g aluminum cylinder that you take from your freezer and place in a mug of hot coffee. If the cylinder is cooled to -20∘C, a typical freezer temperature, and then dropped into a large cup of coffee (essentially water, with a mass...

Enter your answer in the provided box. At a local convenience store, you purchase a cup of coffee, but, at 98.4°C, it is too hot to drink. You add 41.7 g of ice that is −2.2°C to the 248 mL of coffee. What is the final temperature of the coffee? (Assume the heat capacity and density of the coffee are the same as water and the coffee cup is well insulated.)

Synthesis of n-Butyl Bromide Purpose of the Experiment: In this week's experiment you will be synthesizing n-butylbromide (IUPAC 1-bromobutane from 1-butanol and a concentrated acid via a nucleophilie substitution reaction. It is important to know that alcohols dehydrate to form alkenes in the presence of strong inorganic acids, so care must be taken in this experiment not to heat the reaction too vigorously else an elimination reaction may...

What are the desirable characteristics of a solvent to be used
in the recrystallisation of a solid product? (Hint: what is the
underlying purpose of doing recrystallisation, aside from making
the product look attractive?)
EXPERIMENT5 PREPARATION OF BENZOIC ACID Oxidation of a Primary Alcohol In this experiment, a primary alcohol (benzyl alcohol) is oxidised to a carboxylic acid (benzoic acid) by a strong oxidising agent (potassium permanganate) Because the synthesis reaction is carried out in basic conditions, the carboxylic acid...
