1. Use the three-step method described in the module to predict the actual precipitates which form (if such is the case) when the following solutions are mixed:
a) silver sulphate and barium chloride
b) ammonium iodide and potassium phosphate
c) lead (II) acetate and rubidium bromide
Complete the reaction of salicylic acid and 4-aminobenzenesulfonic acid by drawing the expected product.
A synthesis gas analyzing 6.4% CO2, 0.2% O2, 40.0% CO, and 50.8% H2, (the balance is N2), is burned with 40% dry excess air. What is the composition of the flue gas
Determine the boiling point of a solution that contains 78.8 g of naphthalene (C10H8) dissolved in 722 mL of benzene (d = 0.877 g/mL). Pure benzene has a boiling point of 80.1°C and a boiling point elevation constant of 2.53°C/m.
