Suppose you have a mixture of 2 substances. You know one of the substances is either 2-chlorobenzoic acid or diphenyl acetic acid. The second substance is either p-dibromobenzene or acenaphthylene. Describe how you would separate the two substances, and once they are separated, how you would identify which two substances you have.
Initially, .500 atm of H2 and .500 atm I 2 are mixed in an evacuated 1.0 L flask. The system is allowed to come to equilibrium and it is found tocontain 0.368 atm HI. What is the equilibrium partial pressure of I2 for the reaction shown below
A student synthesized benzyl acetate following Fischer esterification, and combined 3.4 mL benzyl alcohol (MW = 108.14 g/mol, ?= 1.044 g/mL) and 0.57 mL acetic acid (MW = 60.05 g/mol, , ?= 1.049 g/mL) under reflux for 50 minutes.
Imagine that you place a cork measuring 1.30cm x 5.50cm x 3.00cm in a pan of water and that on top of the cork you place a small cube of lead measuring 1.15cm on each edge. The density of cork is 0.235g/cm3, and the density of lead is 11.35g/cm3.
