There are about 1.5 x 109 scrap tires in the world at the moment; this represents a major waste disposal problem.
a. If all of these tires were burned with complete efficiency, by how much (in tonnes) would Earth's current atmospheric load of C02 increase?
b. Compare this to the current atmospheric C02 load. Assume rubber has a molecular formulaof C200H400 and that each scrap tire weighs 8 kg, has a diameter of 48 cm, and is 85% rubber.
Conjugated diene addition reaction, a) When HCl is added to 1,3-butadiene either 3-chloro-1-butene or 1-chloro-2-butene forms. Which product is more stable? Explain.
You believe your unknown compound is acetanilide that melts at 114-115 degrees, so you ask your professor for a sample of the pure compound to do a mixed melting point. You do the experiment and determine the mixed melting point is 106-110 degrees..
The chlorinator feed rate is 4.0 mg/L and the free chlorine residual is 1.5 mg/L. (a) What is the chlorine demand (mg/L)? (b) How many kg of chlorine must be fed to the plant on a daily basis?

When a 2.691 g sample of the unknown organic compound is vaporized at 90.0(degrees)C and 708. mmHg it is found to occupy a volume of 1.00L.
A student has a sample (less than 100 mg) that she would like to test for presence of lead. She has access two different atomic absorption spectrometers (flame and furnace) that could be used for analysis.
Inexperienced athletes might try consuming three high energy drinks just before a race but veteran marathon runners know this would impair their performance. Why?
Calculate the freezing point of a 2 molal solution of a nonelectrolyte glucose. feezing point constant for water being 1.86 C/molal
neutral compound show traces of an acid as an impurity wheras the acid might not show any traces of a neutral compound?
In solving weak acid equilibrium problems to find [H+] or pH, a major assumption is usually made. This major assumption can be represented by the following
The heat of combustion of naphthalene (C10H8) is - 5157 kJ/mol. Using these data and data in Appendix C, calculate the heat of hydrogenation of naphthalene.
