... The specific heat of gold is 0.13 J g–1 K–1, and that of copper is 0.39 J g–1 K–1. Suppose that we heat both a 25-g sample of gold and a 25-g sample of copper to 80°C and then drop each into identical beakers containing 100 mL of cold water at 10°C. When each beaker reaches thermal equilibrium, whic ...

... Traditionally, there are three general ways of converting alkenes into alcohols. The first route requires protonation of the C=C bond to form a carbocation intermediate, which is then attacked by water to give an alcohol (Scheme 1, eq. 1). Selective formation of the thermodynamically-preferred carbo ...

... A rough estimate for a generic uptake coefficient for NO3 uptake to saturated alcohols or carbonyls can be made using kb = 6 104 M-1 s-1 (equivalent to a gas-phase rate constant of 1 10-16 cm3 molecule-1 s-1), Dl, = 2 10-5 cm2 s-1, and H = 0.8 Matm-1, this expression results in a value of = ...

... The direction in which you write the chemical equation for an equilibrium is arbitrary, because equilibrium can be approached from either direction. The equilibrium constant expression for a reaction written in one direction is the reciprocal of the one for the reaction in the reverse direction. The ...

Synthesis of enantiopure alcohols (R)-1-Phenoxy-2-butanol ((R)-1) The butanoate of 1-phenoxy-2-butanol, 1a, (0.8691g, 3.68 mmole) was hydrolyzed by addition of CAL-B Novozym 435 (0.105 g) in phosphate buffer (0.1 M, 183.5 mL). The enantiopure alcohol (R)-1 was separated from the remaining butanoate ...
