Phenacetin can be prepared from p-acetamidophenol, which has a molar mass of 151.16 g/mol, and bromoethane, which has a molar mass of 108.97 g/mol. The density of bromoethane is 1.47 g/mL. One-to-one reaction of p-acetamidophenol with bromoethane to form phenacetin What is the yield in grams of phenacetin, which has a molar mass of 179.22 g/mol, possible when reacting 0.151 g of p-acetamidophenol with 0.12 mL of bromoethane

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.
