Write a detailed sheet/ flow chart for the isolation and purification of 1-bromobutane. Designate how each minor-product is removed form the major product and which layer holds the product in each experimental step performed.
A 4.50-g sample of liquid water at 25.0 C is heated by the addition of 133 J of energy. The final temperature of the water is __________ °C. The specific heat capacity of liquid water is 4.18 J/gK.
Organic chemistry solution - First question wants the product of certain oxidation reaction of chromic acid with a secondary alcohol and primary alcohol.
25.0 mL of ethanol (density = 0.789 g/mL) initially at 7.4°C is mixed with 32.1 mL of water (density = 1.0 g/mL) initially at 25.3°C in an insulated beaker. Assuming that no heat is lost, what is the final temperature of the mixture?
