Why are boiling chips added to the round bottom flasks of both simple and fractional distillations? Explain in detail the ramifications (cause and effect) of not adding boiling chips to your flask before performing a distillation.
Calculate the volume of hexane that you need at minimum, if you want to extract at least 95% of the total 1,2,4-TCB present in the water sample
What is the expected Nernst responce, in mV, for each decade change in the gydrogen ion concentration for a glass electrode
A solution was prepared by adding beneze(C6H6) to 405.4g of cyclohexane(C6H12). Freezing point of the soluiton was measured and the deltaTf was 42.3degree celcius. How mnany moles of beneze were added to the solvent for the change to occur

State whether you would expect the entropy change, delta S, to be positive, negative, or approximately zero for each of the following reactions: (a) A + B --> C (b) A + B --> C + D (c) A --> B + C Please explain.
Monel metal is a corrosion-resistant copper-nickel alloy used in the electronics industry. A particular alloy with a density of 8.80 g/ cm^3. and containing 0.074 % Si by mass is used to make a rectangular plate that is 15.0 cm long,
Acetic acid, HC2H3O2, is a weak acid (Ka= 1.8 * 10^-5). solution A is 100.0mL of 0.10 M acetic acid, and Solution B is prepare by adding 0.0050 mol solid NaOH to solution A. One more 0.0050 mol of solid NaOH is added to solution Solution B to make..
