Estimate the liquid diffusivity of the following solutes that are transferred through dilute solutions: a. oxygen in ethanol at 293 k; b. methanol in water at 283 k; c. water in methanol at 288 k; d. n-butanol in water at 288 k. compare this value with experimental value reported in appendix j.2

b) nuclear ive learned that in a pedtrodic table

the objects have the same charge is correct.

it is the minimum amount of material needed to sustain a fission reaction.

critical mass is the minimum amount of fissionable material that must be assembled for a sustained fission reaction to take place. although two to three neutrons are produced for every fission, not all of these neutrons are available for continuing the fission reaction. if the conditions are such that the neutrons are lost at a faster rate than they are formed by fission, the chain reaction will not be self-sustaining.   at the point where the chain reaction can become self-sustaining, this is referred to as critical mass.
