Quantitative Chemical Analysis 8
(a) When a solution containing 234 mg of butanol (FM 74.12) and 312 mg of hexanol (FM 102.17) in 10.0 mL was separated by gas chromatography, the relative peak areas were butanol:hexanol 1.00:1.45. Considering butanol to be the internal standard, find the response factor for hexanol. (b) Use Equation

Urban Economics 8
Predict Wages and Employment In the city of Growville, the equilibrium employment is 100,000 workers, and the equilibrium wage is $100 per day. The elasticity of demand for labor is 1.0 (in absolute value) and the elasticity of supply of labor is 5.0. The employment multiplier is 2.0. Suppose the dem

An archaeologist sometime in the future analyzes the iron used in an old building. The iron contains tiny amounts of nickel-63, with a half-life of 92 years. On the basis of the amount of nickel-63 and its decay products found, it is estimated that about 0.78% (1/128) of the original nickel-63 remain

Biochemistry 9
Consider the following in light of the concept of levels of structure (primary, secondary, tertiary, quaternary) as defined for proteins. (a) What level is shown by double-stranded DNA? (b) What level is shown by tRNA? (c) What level is shown by mRNA?
