Asolid is to be comminuted as to increase its solubility by 10%, that is, s/s0 is to become 1.10. what must be the final particle size, assuming that the surface tension of the solid is 100 dynes/cm and the volume per mole is 50 cm3. the temperature is 27°c.

Stage in which a typical star has completely stopped fusion

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.

An unsaturated hydrocarbon is a hydrogen-carbon compound with a. a network solid structure b. single bonds c. single bonds in a branched-chain structure d. double or triple bonds
